 Introduction
 
 This index is designed to quickly identify the STF 1 tables needed.  Each
 table variable is listed alphabetically.  Both the type of entry being
 tabulated (universe), which is shown in italics, and the relevant table
 numbers appear under the variable heading.  If the entry variable is cross
 tabulated by another variable, the variable of cross tabulation is
 indicated beneath the universe preceded by the word "by."  The index
 entries for each variable are arranged alphabetically by universe, then by
 variable of cross tabulation, if any.  For example, if you are looking for
 a table tabulating age by sex by race for all persons, check the index
 under any of the three variables.  Checking under age, you find entries for
 three tables.  Two tables (P11 and P12) have a universe of persons while
 one table (P13) has a universe of persons of Hispanic origin.  Checking the
 P11 and P12 entries, you can see that age is cross tabulated by sex and
 race in table P12.

 American Indian and Alaska Native Area

 Alaska Native Regional Corporation

 Alaska Native Regional Corporations (ANRC's) are corporate entities
 established under the Alaska Native Claims Settlement Act of 1972, Public
 Law 92-203, as amended by Public Law 94-204, to conduct both business and
 nonprofit affairs of Alaska Natives. Alaska is divided into 12 ANRC's that
 cover the entire State, except for the Annette Islands Reserve. The
 boundaries of the 12 ANRC's were established by the Department of the
 Interior, in cooperation with Alaska Natives. Each ANRC was designed to
 include, as far as practicable, Alaska Natives with a common heritage and
 common interests. The ANRC boundaries for the 1990 census were identified
 by the Bureau of Land Management. A 13th region was established for Alaska
 Natives who are not permanent residents and who chose not to enroll in
 one of the 12 ANRC's; no census products are prepared for the 13th
 region. ANRC's were first identified for the 1980 census.

   Each ANRC is assigned a two-digit census code ranging from 07 through
 84. These census codes are assigned in alphabetical order of the
 ANRC's.


 Alaska Native Village Statistical Area

 Alaska Native villages (ANV's) constitute tribes, bands, clans, groups,
 villages, communities, or associations in Alaska that are recognized
 pursuant to the Alaska Native Claims Settlement Act of 1972, Public Law
 92-203. Because ANV's do not have legally designated boundaries, the Census
 Bureau has established Alaska Native village statistical areas (ANVSA's)
 for statistical purposes. For the 1990 census, the Census Bureau cooperated
 with officials of the nonprofit corporation within each participating
 Alaska Native Regional Corporation (ANRC), as well as other knowledgeable
 officials, to delineate boundaries that encompass the settled area
 associated with each ANV. ANVSA's are located within ANRC's and do not
 cross ANRC boundaries. ANVSA's for the 1990 census replace the ANV's that
 the Census Bureau recognized for the 1980 census.

   Each ANVSA is assigned a four-digit census code ranging from 6001
 through 8989. Each ANVSA also is assigned a five-digit FIPS code. Both
 the census and FIPS codes are assigned in alphabetical order of ANVSA's.

 American Indian Reservation and Trust Land

 American Indian Reservation--Federal American Indian reservations are areas
 with boundaries established by treaty, statute, and/or executive or court
 order, and recognized by the Federal Government as territory in which
 American Indian tribes have jurisdiction. State reservations are lands held
 in trust by State governments for the use and benefit of a given tribe.
 The reservations and their boundaries were identified for the 1990
 census by the Bureau of Indian Affairs (BIA), Department of Interior
 (for Federal reservations), and State governments (for State reservations).
 The names of American Indian reservations recognized by State governments,
 but not by the Federal Government, are followed by "(State)." Areas
 composed of reservation lands that are administered jointly and/or are
 claimed by two reservations, as identified by the BIA, are called "joint
 areas," and are treated as separate American Indian reservations for census
 purposes.

 Federal reservations may cross State boundaries, and Federal and State
 reservations may cross county, county subdivision, and place boundaries.
 For reservations that cross State boundaries, only the portion of the
 reservations in a given State are shown in the data products for that
 State; the entire reservations are shown in data products for the United
 States.

 Each American Indian reservation is assigned a four-digit census code
 ranging from 0001 through 4989. These census codes are assigned in
 alphabetical order of American Indian reservations nationwide, except
 that joint areas appear at the end of the code range. Each American
 Indian reservation also is assigned a five-digit FIPS code; because the
 FIPS codes are assigned in alphabetical sequence of American Indian
 reservations within each State, the FIPS code is different in each
 State for reservations in more than one State.

 Trust Land--Trust lands are property associated with a particular American
 Indian reservation or tribe, held in trust by the Federal Government. Trust
 lands may be held in trust either for a tribe (tribal trust land) or
 for an individual member of a tribe (individual trust land). Trust
 lands recognized for the 1990 census comprise all tribal trust lands
 and inhabited individual trust lands located outside of a reservation
 boundary. As with other American Indian areas, trust lands may be
 located in more than one State. Only the trust lands in a given State
 are shown in the data products for that State; all trust lands
 associated with a reservation or tribe are shown in data products for
 the United States. The Census Bureau first reported data for tribal
 trust lands for the 1980 census.

 Trust lands are assigned a four-digit census code and a five-digit FIPS
 code, the same as that for the reservation with which they are
 associated. Trust lands not associated with a reservation are presented
 by tribal name, interspersed alphabetically among the reservations.

 Tribal Designated Statistical Area (TDSA)

 Tribal designated statistical areas (TDSA's) are areas, delineated
 outside Oklahoma by federally- and State-
 recognized tribes without a land base or associated trust lands, to
 provide statistical areas for which the Census Bureau tabulates data.
 TDSA's represent areas generally containing the American Indian
 population over which federally-recognized tribes have jurisdiction and
 areas in which State tribes provide benefits and services to their
 members. The names of TDSA's delineated by State-recognized tribes are
 followed by "(State)." The Census Bureau did not recognize TDSA's
 before the 1990 census.

 Each TDSA is assigned a four-digit census code ranging from 9001
 through 9589. The census codes are assigned in alphabetical order of
 TDSA's nationwide. Each TDSA also is assigned a five-digit FIPS code in
 alphabetical order within State.

 Tribal Jurisdiction Statistical Area (TJSA)

 Tribal jurisdiction statistical areas (TJSA's) are areas,
 delineated by federally-recognized tribes in Oklahoma without a
 reservation, for which the Census Bureau tabulates data. TJSA's
 represent areas generally containing the American Indian population
 over which one or more tribal governments have jurisdiction; if tribal
 officials delineated adjacent TJSA's so that they include some
 duplicate territory, the overlap area is called a "joint use
 area," which is treated as a separate TJSA for census purposes.

 TJSA's replace the "Historic Areas of Oklahoma (excluding urbanized
 areas)" shown in 1980 census data products. The Historic Areas of
 Oklahoma comprised the territory located within reservations that had
 legally established boundaries from 1900 to 1907; these reservations
 were dissolved during the 2- to 3-year period preceding the statehood
 of Oklahoma in 1907. The Historic Areas of Oklahoma (excluding
 urbanized areas) were identified only for the 1980 census.

 Each TJSA is assigned a four-digit census code ranging from 5001
 through 5989. The census codes are assigned in alphabetical order of
 TJSA's, except that joint areas appear at the end of the code range.
 Each TJSA also is assigned a five-digit FIPS code in alphabetical order
 within Oklahoma.

 Area Measurement

 Area measurements provide the size, in square kilometers (also in square
 miles in printed reports), recorded for each geographic entity for which
 the Census Bureau tabulates data in general-purpose data products (except
 crews-of-vessels entities and ZIP Codes). (Square kilometers may be divided
 by 2.59 to convert an area measurement to square miles.) Area was
 calculated from the specific set of boundaries recorded for the entity in
 the Census Bureau's geographic data base (see "TIGER"). On machine-readable
 files, area measurements are shown to three decimal places; the decimal
 point is implied. In printed reports and listings, area measurements are
 shown to one decimal.

 The Census Bureau provides measurements for both land area and total
 water area for the 1990 census; the water figure includes inland,
 coastal, Great Lakes, and territorial water. (For the 1980 census, the
 Census Bureau provided area measurements for land and inland water.)
 The Census Bureau will provide measurements for the component types of
 water for the affected entities in a separate file. "Inland
 water" consists of any lake, reservoir, pond, or similar body of
 water that is recorded in the Census Bureau's geographic data base. It
 also includes any river, creek, canal, stream, or similar feature that
 is recorded in that data base as a two-dimensional feature (rather than as
 a single line). The portions of the oceans and related large embayments
 (such as the Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the
 Caribbean Sea that belong to the United States and its possessions are
 considered to be "coastal" and "territorial" waters; 
 the Great Lakes are treated as a separate water entity. Rivers and bays 
 that empty into these bodies of water are treated as "inland water" 
 from the point beyond which they are narrower than one nautical mile across.
 Identification of land and inland, coastal, and territorial waters is
 for statistical purposes, and does not necessarily reflect legal
 definitions thereof.

 By definition, census blocks do not include water within their
 boundaries; therefore, the water area of a block is always zero. Land
 area measurements may disagree with the information displayed on census
 maps and in the TIGER file because, for area measurement purposes,
 features identified as "intermittent water" and "glacier" are reported as
 land area. For this reason, it may not be possible to derive the land area
 for an entity by summing the land area of its component census blocks. In
 addition, the water area measurement reported for some geographic entities
 includes water that is not included in any lower-level geographic entity.
 Therefore, because water is contained only in a higher-level geographic
 entity, summing the water measurements for all the component lower-level
 geographic entities will not yield the water area of that higher-level
 entity. This occurs, for example, where water is associated with a county
 but is not within the legal boundary of any minor civil division, or the
 water is associated with a State but is not within the legal boundary of
 any county. Crews-of-vessels entities (see "Census Tract and Block
 Numbering Area" and "Block") do not encompass territory and therefore have
 no area measurements. ZIP Codes do not have specific boundaries, and
 therefore, also do not have area measurements.

 The accuracy of any area measurement figure is limited by the
 inaccuracy inherent in (1) the location and shape of the various
 boundary features in the data base, and (2) rounding affecting the last
 digit in all operations that compute and/or sum the area measurements.

 Block

 Census blocks are small areas bounded on all sides by visible features such
 as streets, roads, streams, and railroad tracks, and by invisible
 boundaries such as city, town, township, and county limits, property lines,
 and short, imaginary extensions of streets and roads.

 Tabulation blocks, used in census data products, are in most cases the
 same as collection blocks, used in the census enumeration. In some
 cases, collection blocks have been "split" into two or more parts
 required for data tabulations. Tabulation blocks do not cross the
 boundaries of counties, county subdivisions, places, census tracts or
 block numbering areas, American Indian and Alaska Native areas,
 congressional districts, voting districts, urban or rural areas, or
 urbanized areas. The 1990 census is the first for which the entire
 United States and its possessions are block-numbered.

 Blocks are numbered uniquely within each census tract or BNA. A block
 is identified by a three-digit number, sometimes with a single
 alphabetical suffix. Block numbers with suffixes generally represent
 collection blocks that were "split" in order to identify separate
 geographic entities that divide the original block. For example, when a
 city limit runs through data collection block 101, the data for the
 portion inside the city is tabulated in block 101A and the portion
 outside, in block 101B. A block number with the suffix "Z"
 represents a "crews-of-vessels" entity for which the Census
 Bureau tabulates data, but that does not represent a true geographic
 area; such a block is shown on census maps associated with an anchor
 symbol and a census tract or block numbering area with a .99 suffix.


 Block Group (BG)

 Geographic Block Group

 A geographic block group (BG) is a cluster of blocks having the same
 first digit of their three-digit identifying numbers within a census
 tract or block numbering area (BNA). For example, BG 3 within a census
 tract or BNA includes all blocks numbered between 301 and 397. In most
 cases, the numbering involves substantially fewer than 97 blocks.
 Geographic BG's never cross census tract or BNA boundaries, but may
 cross the boundaries of county subdivisions, places, American Indian
 and Alaska Native areas, urbanized areas, voting districts, and
 congressional districts. BG's generally contain between 250 and 550
 housing units, with the ideal size being 400 housing units.

 Tabulation Block Group
 In the data tabulations, a geographic BG may be split to present
 data for every unique combination of county subdivision, place,
 American Indian and Alaska Native area, urbanized area, voting
 district, urban/rural and congressional district shown in the data
 product; for example, if BG3 is partly in a city and partly outside the
 city, there will be separate tabulated records for each portion of BG3.
 BG's are used in tabulating decennial census data nationwide in the
 1990 census, in all block-numbered areas in the 1980 census, and in
 Tape Address Register (TAR) areas in the 1970 census. For purposes of
 data presentation, BG's are a substitute for the enumeration districts
 (ED's) used for reporting data in many parts of the United States for
 the 1970 and 1980 censuses, and in all areas for pre-1970 censuses.

 Boundary Changes

 The boundaries of some counties, county subdivisions, American
 Indian and Alaska Native areas, and many incorporated places, changed
 between those reported for the 1980 census and January 1, 1990.
 Boundary changes to legal entities result from:

 1.  Annexations to or detachments from legally established governmental
     units.

 2.  Mergers or consolidations of two or more governmental units.

 3.  Establishment of new governmental units.

 4.  Disincorporations or disorganizations of existing governmental
     units.

 5.  Changes in treaties and Executive Orders.

 The historical counts shown for counties, county subdivisions, and
 places are not updated for such changes, and thus reflect the
 population and housing units in the area as delineated at each census.
 Information on boundary changes reported between the 1980 and 1990
 censuses for counties, county subdivisions, and incorporated places is
 presented in the "User Notes" section of the technical documentation of
 Summary Tape Files 1 and 3, and in the 1990 CPH-2, Population and Housing
 Unit Counts printed reports. For information on boundary changes for such
 areas in the decade preceding other decennial censuses, see the Number of
 Inhabitants reports for each census. Boundary changes are not reported for
 some areas, such as census designated places and block groups.


 Census Region and Census Division

 Census Division

 Census divisions are groupings of States that are subdivisions of
 the four census regions. There are nine divisions, which the Census
 Bureau adopted in 1910 for the presentation of data. The regions,
 divisions, and their constituent States are:


 Northeast Region

 New England Division:

 Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut

 Middle Atlantic Division:

 New York, New Jersey, Pennsylvania

 Midwest Region

 East North Central Division:

 Ohio, Indiana, Illinois, Michigan, Wisconsin

 West North Central Division:

 Minnesota, Iowa, Missouri, North Dakota, South Dakota, Nebraska, Kansas


 South Region

 South Atlantic Division:

 Delaware, Maryland, District of Columbia, Virginia, West Virginia, North
 Carolina, South Carolina, Georgia, Florida

 East South Central Division:

 Kentucky, Tennessee, Alabama, Mississippi

 West South Central Division:

 Arkansas, Louisiana, Oklahoma, Texas

 West Region

 Mountain Division:

 Montana, Idaho, Wyoming, Colorado, New Mexico, Arizona, Utah, Nevada

 Pacific Division:

 Washington, Oregon, California, Alaska, Hawaii


 Census Region

 Census regions are groupings of States that subdivide the United
 States for the presentation of data. There are four regions--Northeast,
 Midwest, South, and West. Each of the four census regions is divided
 into two or more census divisions. Prior to 1984, the Midwest region
 was named the North Central region. From 1910, when census regions were
 established, through the 1940's, there were three regions--North, South,
 and West.


 Census Tract and Block Numbering Area

 Block Numbering Area (BNA)

 Block numbering areas (BNA's) are small statistical subdivisions of
 a county for grouping and numbering blocks in nonmetropolitan counties
 where local census statistical areas committees have not established
 census tracts. State agencies and the Census Bureau delineated BNA's
 for the 1990 census, using guidelines similar to those for the
 delineation of census tracts. BNA's do not cross county boundaries.

 BNA's are identified by a four-digit basic number and may have a
 two-digit suffix; for example, 9901.07. The decimal point separating
 the four-digit basic BNA number from the two-digit suffix is shown in
 printed reports, in microfiche, and on census maps; in machine-readable
 files, the decimal point is implied. Many BNA's do not have a suffix;
 in such cases, the suffix field is left blank in all data products. BNA
 numbers range from 9501 through 9989.99, and are unique within a county
 (numbers in the range of 0001 through 9499.99 denote a census tract).
 The suffix .99 identifies a BNA that was populated entirely by persons
 aboard one or more civilian or military ships. A "crews-of-vessels" BNA
 appears on census maps only as an anchor symbol with its BNA number (and
 block numbers on maps showing block numbers); the BNA relates to the ships
 associated with the onshore BNA's having the same four-digit basic number.
 Suffixes in the range .80 through .98 usually identify BNA's that either
 were revised or were created during the 1990 census data collection
 activities. Some of these revisions produced BNA's that have extremely
 small land area and ay have little or no population or housing. For data
 analysis, such a BNA can be summarized with an adjacent BNA.

 Census Tract

 Census tracts are small, relatively permanent statistical subdivisions of a
 county. Census tracts are delineated for all metropolitan areas (MA's) and
 other densely populated counties by local census statistical areas
 committees following Census Bureau guidelines (more than 3,000 census
 tracts have been established in 221 counties outside MA's). Six States
 (California, Connecticut, Delaware, Hawaii, New Jersey, and Rhode Island)
 and the District of Columbia are covered entirely by census tracts. Census
 tracts usually have between 2,500 and 8,000 persons and, when first
 delineated, are designed to be homogeneous with respect to population
 characteristics, economic status, and living conditions. Census tracts do
 not cross county boundaries. The spatial size of census tracts varies
 widely depending on the density of settlement. Census tract boundaries are
 delineated with the intention of being maintained over a long time so that
 statistical comparisons can be made from census to census. However,
 physical changes in street patterns caused by highway construction, new
 development, etc., may require occasional revisions; census tracts
 occasionally are split due to large population growth, or combined as a
 result of substantial population decline. Census tracts are referred to
 as "tracts" in all 1990 data products.

 Census tracts are identified by a four-digit basic number and may have
 a two-digit suffix; for example, 6059.02. The decimal point separating
 the four-digit basic tract number from the two-digit suffix is shown in
 printed reports, in microfiche, and on census maps; in machine-readable
 files, the decimal point is implied. Many census tracts do not have a
 suffix; in such cases, the suffix field is left blank in all data
 products. Leading zeros in a census tract number (for example, 002502)
 are shown only on machine-readable files.

 Census tract numbers range from 0001 through 9499.99 and are unique
 within a county (numbers in the range of 9501 through 9989.99 denote a
 block numbering area). The suffix .99 identifies a census tract that
 was populated entirely by persons aboard one or more civilian or
 military ships. A "crews-of-vessels" census tract appears on
 census maps only as an anchor symbol with its census tract number (and
 block numbers on maps showing block numbers). These census tracts
 relate to the ships associated with the on-shore census tract having
 the same four-digit basic number. Suffixes in the range .80 through .98
 usually identify census tracts that either were revised or were created
 during the 1990 census data collection activities. Some of these
 revisions may have resulted in census tracts that have extremely small
 land area and may have little or no population or housing. For data
 analysis, such a census tract can be summarized with an adjacent census
 tract.

 Congressional District

 Congressional districts (CD's) are the 435 areas from which persons
 are elected to the U.S. House of Representatives. After the
 apportionment of congressional seats among the States, based on census
 population counts, each State is responsible for establishing CD's for
 the purpose of electing representatives. Each CD is to be as equal in
 population to all other CD's in the State as practicable, based on the
 decennial census counts.

 The CD's that were in effect on January 1, 1990 were those of the 101st
 Congress. Data on the 101st Congress appear in an early 1990 census
 data product (Summary Tape File 1A). The CD's of the 101st Congress are
 the same as those in effect for the 102nd Congress. CD's of the 103rd
 Congress, reflecting redistricting based on the 1990 census, are
 summarized in later 1990 data products (STF's 1D and 3D, and 1990
 CPH-4, Population and Housing Characteristics for Congressional
 Districts of the 103rd Congress printed reports).

 County

 The primary political divisions of most States are termed "counties." In
 Louisiana, these divisions are known as "parishes." In Alaska, which has no
 counties, the county equivalents are the organized "boroughs" and the
 "census areas" that are delineated for statistical purposes by the State of
 Alaska and the Census Bureau. In four States (Maryland, Missouri, Nevada,
 and Virginia), there are one or more cities that are independent of any
 county organization and thus constitute primary divisions of their States.
 These cities are known as "independent cities" and are treated as
 equivalent to counties for statistical purposes. That part of Yellowstone
 National Park in Montana is treated as a county equivalent. The District of
 Columbia has no primary divisions, and the entire area is considered
 equivalent to a county for statistical purposes.

 Each county and county equivalent is assigned a three-digit FIPS code
 that is unique within State. These codes are assigned in alphabetical
 order of county or county equivalent within State, except for the
 independent cities, which follow the listing of counties.

 County Subdivision

 Description

 County subdivisions are the primary subdivisions of counties and their
 equivalents for the reporting of decennial census data. They include census
 county divisions, census subareas, minor civil divisions, and unorganized
 territories.

 Each county subdivision is assigned a three-digit census code in
 alphabetical order within county and a five-digit FIPS code in alphabetical
 order within State.

 Census County Division

 Census county divisions (CCD's) are subdivisions of a county that were
 delineated by the Census Bureau, in cooperation with State officials and
 local census statistical areas committees, for statistical purposes. CCD's
 were established in 21 States where there are no legally established minor
 civil divisions (MCD's), where the MCD's do not have governmental or
 administrative purposes, where the boundaries of the MCD's change
 frequently, and/or where the MCD's are not generally known to the public.
 CCD's have no legal functions, and are not governmental units.

 The boundaries of CCD's usually are delineated to follow visible
 features, and in most cases coincide with census tract or block
 numbering area boundaries. The name of each CCD is based on a place,
 county, or well-known local name that identifies its location. CCD's
 have been established in the following 21 States: Alabama, Arizona,
 California, Colorado, Delaware, Florida, Georgia, Hawaii, Idaho,
 Kentucky, Montana, Nevada, New Mexico, Oklahoma, Oregon, South
 Carolina, Tennessee, Texas, Utah, Washington, and Wyoming. For the 1980
 census, the county subdivisions recognized for Nevada were MCD's.

 Census Subarea (Alaska)

 Census subareas are statistical subdivisions of boroughs and census
 areas (county equivalents) in Alaska. Census subareas were delineated
 cooperatively by the State of Alaska and the Census Bureau. The census
 subareas, identified first in 1980, replaced the various types of
 subdivisions used in the 1970 census.

 Minor Civil Division

 Minor civil divisions (MCD's) are the primary political or
 administrative divisions of a county. MCD's represent many different
 kinds of legal entities with a wide variety of governmental and/or
 administrative functions. MCD's are variously designated as American
 Indian reservations, assessment districts, boroughs, election
 districts, gores, grants, magisterial districts, parish governing
 authority districts, plantations, precincts, purchases, supervisors'
 districts, towns, and townships. In some States, all or some
 incorporated places are not located in any MCD and thus serve as MCD's
 in their own right. In other States, incorporated places are
 subordinate to (part of) the MCD's in which they are located, or the
 pattern is mixed--some incorporated places are independent of MCD's and
 others are subordinate to one or more MCD's.

 The Census Bureau recognizes MCD's in the following 28 States:
 Arkansas, Connecticut, Illinois, Indiana, Iowa, Kansas, Louisiana,
 Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi,
 Missouri, Nebraska, New Hampshire, New Jersey, New York, North
 Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota,
 Vermont, Virginia, West Virginia, and Wisconsin. The District of
 Columbia has no primary divisions, and the entire area is considered
 equivalent to an MCD for statistical purposes.

 The MCD's in 12 selected States (Connecticut, Maine, Massachusetts,
 Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania,
 Rhode Island, Vermont, and Wisconsin) also serve as general-purpose
 local governments. The Census Bureau presents data for these MCD's in
 all data products in which it provides data for places.

 Unorganized Territory (unorg.)

 In nine States (Arkansas, Iowa, Kansas, Louisiana, Maine,
 Minnesota, North Carolina, North Dakota, and South Dakota), some
 counties contain territory that is not included in an MCD recognized by
 the Census Bureau. Each separate area of unorganized territory in these
 States is recognized as one or more separate county subdivisions for
 census purposes. Each unorganized territory is given a descriptive
 name, followed by the designation "unorg."
 Geographic Code

 Description

 Geographic codes are shown primarily on machine-
 readable data products, such as computer tape and compact disc-read only
 memory (CD-ROM), but also appear on other products such as microfiche;
 they also are shown on some census maps. Codes are identified as
 "census codes" only if there is also a Federal Information Processing
 Standards (FIPS) code for the same geographic entity. A code that is not
 identified as either "census" or "FIPS" is usually a census code for which
 there is no FIPS equivalent, or for which the Census Bureau does not use
 the FIPS code. The exceptions, which use only the FIPS code in census
 products, are county, congressional district, and metropolitan area (that
 is, metropolitan statistical area, consolidated metropolitan statistical
 area, and primary metropolitan statistical area).

 Census Code

 Census codes are assigned for a variety of geographic entities, including
 American Indian and Alaska Native area, census division, census region,
 county subdivision, place, State, urbanized area, and voting district. The
 structure, format, and meaning of census codes appear in the 1990 census
 Geographic Identification Code Scheme; in the data dictionary portion of
 the technical documentation for summary tape files, CD-ROM's, and
 microfiche.

 Federal Information Processing Standards (FIPS) Code

 Federal Information Processing Standards (FIPS) codes are assigned
 for a variety of geographic entities, including American Indian and
 Alaska Native area, congressional district, county, county subdivision,
 metropolitan area, place, and State. The structure, format, and meaning
 of FIPS codes used in the census are shown in the 1990 census
 Geographic Identification Code Scheme; in the data dictionary portion of
 the technical documentation for summary tape files, CD-ROM's, and
 microfiche.

 The objective of the FIPS codes is to improve the use of data resources
 of the Federal Government and avoid unnecessary duplication and
 incompatibilities in the collection, processing, and dissemination of
 data. More information about FIPS and FIPS code documentation is
 available from the National Technical Information Service, Springfield,
 VA 22161.

 United States Postal Service (USPS) Code

 United States Postal Service (USPS) codes for States are used in all
 1990 data products. The codes are two-character alphabetic abbreviations.
 These codes are the same as the FIPS two-character alphabetic
 abbreviations.


 Geographic Presentation

 Hierarchical Presentation

 A hierarchical geographic presentation shows the geographic entities
 in a superior/subordinate structure in census products. This structure
 is derived from the legal, administrative, or areal relationships of
 the entities. The hierarchical structure is depicted in report tables
 by means of indentation, and is explained for machine-readable media in
 the discussion of file structure in the geographic coverage portion of
 the abstract in the technical documentation. An example of hierarchical
 presentation is the "standard census geographic hierarchy":  block, within
 block group, within census tract or block numbering area, within place,
 within county subdivision, within county, within State, within division,
 within region, within the United States. Graphically, this is shown as:

  United States
    Region
      Division
       State
          County
            County subdivision
             Place (or part)
                Census tract/block numbering area (or part)
                 Block group (or part)
                    Block

 Inventory Presentation

 An inventory presentation of geographic entities is one in which all
 entities of the same type are shown in alphabetical or code sequence,
 without reference to their hierarchical relationships. Generally, an
 inventory presentation shows totals for entities that may be split in a
 hierarchical presentation, such as place, census tract/block numbering
 area, or block group. An example of a series of inventory presentations is:
 State, followed by all the counties in that State, followed by all the
 places in that State. Graphically, this is shown as:

      State

      County "A"
      County "B"
      County "C"

      Place  "X"
      Place  "Y"
      Place "Z"


 Historical Counts

 Historical counts for total population and total housing units are
 shown in the 1990 CPH-2, Population and Housing Unit Counts
 report series. As in past censuses, the general rule for presenting
 historical data for States, counties, county subdivisions, and places
 is to show historical counts only for single, continually existing
 entities. Stated another way, if an entity existed for both the current
 and preceding censuses, the tables show counts for the preceding
 censuses. Included in this category are entities of the same type
 (county, county subdivision, place) even if they had changed their
 names. Also included are entities that merged, but only if the new
 entity retained the name of one of the merged entities. The historical
 counts shown are for each entity as it was bounded at each census.

 In cases where an entity was formed since a preceding census, such as a
 newly incorporated place or a newly organized township, the symbol
 three dots "..." is shown for earlier censuses. The three-dot
 symbol also is shown for those parts of a place that have extended into
 an additional county or county subdivision through annexation or other
 revision of boundaries since the preceding census.

 In a few cases, changes in the boundaries of county subdivisions caused
 a place to be split into two or more parts, or to be split differently
 than in the preceding census. If historical counts for the parts of the
 place as currently split did not appear in a preceding census,
 "(NA)" is shown for the place in each county subdivision;
 however, the historical population and housing unit counts of the place
 appear in tables that show the entire place. For counties, county
 subdivisions, and places formed since January 1, 1980, 1980 census
 population and housing unit counts in the 1990 territory are reported
 in the geographic change notes included in the "User Notes" text
 section of 1990 CPH-2, Population and Housing Unit Counts,
 and in the technical documentation of Summary Tape Files 1 and 3.

 In some cases, population and housing unit counts for individual areas
 were revised since publication of the 1980 reports (indicated by the
 prefix "r"). In a number of tables of 1990 CPH-2,
 Population and Housing Unit Counts, 1980 counts are shown
 for aggregations of individual areas, such as the number, population,
 and housing unit counts of places in size groups, or urban and rural
 distributions. Revisions of population and housing unit counts for
 individual areas were not applied to the various aggregations.
 Therefore, it may not be possible to determine the individual areas in
 a given aggregation using the historical counts; conversely, the sum of
 the counts shown for individual areas may not agree with the
 aggregation.

 Internal Point

 An internal point is a set of geographic coordinates (latitude and
 longitude) that is located within a specified geographic entity. A
 single point is identified for each entity; for many entities, this
 point represents the approximate geographic center of that entity. If
 the shape of the entity caused this point to be located outside the
 boundaries of the entity, it is relocated from the center so that it is
 within the entity. If the internal point for a block falls in a water
 area, it is relocated to a land area within the block. On
 machine-readable products, internal points are shown to six decimal
 places; the decimal point is implied.


 Metropolitan Area

 Description

 The general concept of a metropolitan area (MA) is one of a large
 population nucleus, together with adjacent communities that have a high
 degree of economic and social integration with that nucleus. Some MA's
 are defined around two or more nuclei.

 The MA classification is a statistical standard, developed for use by
 Federal agencies in the production, analysis, and publication of data
 on MA's. The MA's are designated and defined by the Federal Office of
 Management and Budget, following a set of official published standards.
 These standards were developed by the interagency Federal Executive
 Committee on Metropolitan Areas, with the aim of producing definitions
 that are as consistent as possible for all MA's nationwide.

 Each MA must contain either a place with a minimum population of 50,000
 or a Census Bureau-defined urbanized area and a total MA population of
 at least 100,000 (75,000 in New England). An MA comprises one or more
 central counties. An MA also may include one or more outlying counties
 that have close economic and social relationships with the central
 county. An outlying county must have a specified level of commuting to
 the central counties and also must meet certain standards regarding
 metropolitan character, such as population density, urban population,
 and population growth. In New England, MA's are composed of cities and
 towns rather than whole counties.

 The territory, population, and housing units in MA's are referred to as
 "metropolitan." The metropolitan category is subdivided into
 "inside central city" and "outside central city." The territory,
 population, and housing units located outside MA's are referred to as
 "nonmetropolitan." The metropolitan and nonmetropolitan classification cuts
 across the other hierarchies; for example, there is generally both urban
 and rural territory within both metropolitan and nonmetropolitan areas.

 To meet the needs of various users, the standards provide for a
 flexible structure of metropolitan definitions that classify an MA
 either as a metropolitan statistical area (MSA), or as a consolidated
 metropolitan statistical area (CMSA) that is divided into primary
 metropolitan statistical areas (PMSA's). Documentation of the MA
 standards and how they are applied is available from the Secretary,
 Federal Executive Committee on Metropolitan Areas, Population Division,
 U.S. Bureau of the Census, Washington, DC 20233.

 Central City

 In each MSA and CMSA, the largest place and, in some cases, additional
 places are designated as "central cities" under the official standards. A
 few PMSA's do not have central cities. The largest central city and, in
 some cases, up to two additional central cities are included in the title
 of the MA; there also are central cities that are not included in an MA
 title. An MA central city does not include any part of that city that
 extends outside the MA boundary.

 Consolidated & Primary Metro. Statistical Area (CMSA and PMSA)

 If an area that qualifies as an MA has more than one million persons,
 primary metropolitan statistical areas (PMSA's) may be defined within it.
 PMSA's consist of a large urbanized county or cluster of counties that
 demonstrates very strong internal economic and social links, in addition to
 close ties to other portions of the larger area.  When PMSA's are
 established, the larger area of which they are component parts is
 designated a consolidated metropolitan statistical area (CMSA).

 Metropolitan Statistical Area (MSA)

 Metropolitan statistical areas (MSA's) are relatively freestanding
 MA's and are not closely associated with other MA's. These areas
 typically are surrounded by nonmetropolitan counties.

 Metropolitan Area Title and Code

 The title of an MSA contains the name of its largest central city,
 and up to two additional city names, provided that the additional
 places meet specified levels of population, employment, and commuting.
 Generally, a city with a population of 250,000 or more is in the title,
 regardless of other criteria.

 The title of a PMSA may contain up to three place names, as determined
 above, or up to three county names, sequenced in order of population. A
 CMSA title also may include up to three names, the first of which
 generally is the most populous central city in the area. The second
 name may be the first city or county name in the most populous
 remaining PMSA; the third name may be the first city or county name in
 the next most populous PMSA. A regional designation may be substituted
 for the second and/or third names in a CMSA title if such a designation
 is supported by local opinion and is deemed to be unambiguous and
 suitable by the Office of Management and Budget.

 The titles for all MA's also contain the name of each State in which
 the area is located. Each metropolitan area is assigned a four-digit
 FIPS code, in alphabetical order nationwide. If the fourth digit of the
 code is a "2," it identifies a CMSA. Additionally, there is a separate set
 of two-digit codes for CMSA's, also assigned alphabetically.

 Outlying Areas of the United States

 The Census Bureau treats the outlying areas as the statistical
 equivalents of States for the 1990 census. The outlying areas are
 American Samoa, Guam, the Northern Mariana Islands, Palau, Puerto Rico,
 and the Virgin Islands of the United States. Geographic definitions
 specific to each outlying area are shown in appendix A of the text in
 the data products for each area.


 Place

 Description

 Places, for the reporting of decennial census data, include census
 designated places and incorporated places. Each place is assigned a
 four-digit census code that is unique within State. Each place is also
 assigned a five-digit FIPS code that is unique within State. Both the
 census and FIPS codes are assigned based on alphabetical order within
 State. Consolidated cities (see below) are assigned a one-character
 alphabetical census code that is unique nationwide and a five-digit
 FIPS code that is unique within State.

 Census Designated Place (CDP)
 
 Census designated places (CDP's) are delineated for the decennial
 census as the statistical counterparts of incorporated places. CDP's
 comprise densely settled concentrations of population that are
 identifiable by name, but are not legally incorporated places. Their
 boundaries, which usually coincide with visible features or the
 boundary of an adjacent incorporated place, have no legal status, nor
 do these places have officials elected to serve traditional municipal
 functions. CDP boundaries may change with changes in the settlement
 pattern; a CDP with the same name as in previous censuses does not
 necessarily have the same boundaries.

 Beginning with the 1950 census, the Census Bureau, in cooperation with
 State agencies and local census statistical areas committees, has
 identified and delineated boundaries for CDP's. In the 1990 census, the
 name of each such place is followed by "CDP." In the 1980 census,
 "(CDP)" was used; in 1970, 1960, and 1950 censuses, these places
 were identified by "(U)," meaning "unincorporated place."

 To qualify as a CDP for the 1990 census, an unincorporated community
 must have met the following criteria:

 1.  In all States except Alaska and Hawaii, the Census Bureau uses
     three population size criteria to designate a CDP. These criteria are:

   a.  1,000 or more persons if outside the boundaries of an urbanized area
       (UA) delineated for the 1980 census or a subsequent special census.

   b.  2,500 or more persons if inside the boundaries of a UA delineated for
       the 1980 census or a subsequent special census.

   c.  250 or more persons if outside the boundaries of a UA delineated for
       the 1980 census or a subsequent special census, and within the
       official boundaries of an American Indian reservation recognized for
       the 1990 census.

 2.  In Alaska, 25 or more persons if outside a UA, and 2,500 or more
     persons if inside a UA delineated for the 1980 census or a subsequent
     special census.

 3.  In Hawaii, 300 or more persons, regardless of whether the community
     is inside or outside a UA.

 For the 1990 census, CDP's qualified on the basis of the population
 counts prepared for the 1990 Postcensus Local Review Program. Because
 these counts were subject to change, a few CDP's may have final
 population counts lower than the minimums shown above.

 Hawaii is the only State with no incorporated places recognized by the
 Bureau of the Census. All places shown for Hawaii in the data products
 are CDP's. By agreement with the State of Hawaii, the Census Bureau
 does not show data separately for the city of Honolulu, which is
 coextensive with Honolulu County.

 Consolidated City

 A consolidated government is a unit of local government for which
 the functions of an incorporated place and its county or minor civil
 division (MCD) have merged. The legal aspects of this action may result
 in both the primary incorporated place and the county or MCD continuing
 to exist as legal entities, even though the county or MCD performs few
 or no governmental functions and has few or no elected officials. Where
 this occurs, and where one or more other incorporated places in the
 county or MCD continue to function as separate governments, even though
 they have been included in the consolidated government, the primary
 incorporated place is referred to as a "consolidated city."

 The data presentation for consolidated cities varies depending upon the
 geographic presentation. In hierarchical presentations, consolidated
 cities are not shown. These presentations include the semi-independent
 places and the "consolidated city (remainder)." Where the
 consolidated city is coextensive with a county or county subdivision,
 the data shown for those areas in hierarchical presentations are
 equivalent to those for the consolidated government.

 For inventory geographic presentations, the consolidated city appears
 at the end of the listing of places. The data for the consolidated city
 include places that are part of the consolidated city. The "consolidated
 city (remainder)" is the portion of the consolidated government minus the
 semi-independent places, and is shown in alphabetical sequence with other
 places.

 In summary presentations by size of place, the consolidated city is not
 included. The places semi-independent of consolidated cities are
 categorized by their size, as is the "consolidated city (remainder)."

 Each consolidated city is assigned a one-character alphabetic census
 code. Each consolidated city also is assigned a five-digit FIPS code
 that is unique within State. The semi-independent places and the
 "consolidated city (remainder)" are assigned a four-digit census
 code and a five-digit FIPS place code that are unique within State.
 Both the census and FIPS codes are assigned based on alphabetical order
 within State.

 Incorporated Place

 Incorporated places recognized in 1990 census data products are
 those reported to the Census Bureau as legally in existence on January
 1, 1990 under the laws of their respective States as cities, boroughs,
 towns, and villages, with the following exceptions: the towns in the
 New England States, New York, and Wisconsin, and the boroughs in New
 York are recognized as minor civil divisions for census purposes; the
 boroughs in Alaska are county equivalents.

 Population or Housing Unit Density

 Population or housing unit density is computed by dividing the total
 population or housing units of a geographic unit (for example, United
 States, State, county, place) by its land area measured in square
 kilometers or square miles. Density is expressed as both "persons
 (or housing units) per square kilometer" and "persons (or housing
 units) per square mile" of land area in 1990 census printed reports.


 State

 States are the primary governmental divisions of the United States.
 The District of Columbia is treated as a statistical equivalent of a
 State for census purposes. The four census regions, nine census
 divisions, and their component States are shown under "CENSUS REGION
 AND CENSUS DIVISION" in this appendix.

 The Census Bureau treats the outlying areas as State equivalents for
 the 1990 census. The outlying areas are American Samoa, Guam, the
 Northern Mariana Islands, Palau, Puerto Rico, and the Virgin Islands of
 the United States. Geographic definitions specific to each outlying
 area are shown in appendix A in the data products for each area.

 Each State and equivalent is assigned a two-digit numeric Federal
 Information Processing Standards (FIPS) code in alphabetical order by
 State name, followed by the outlying area names. Each State and
 equivalent area also is assigned a two-digit census code. This code is
 assigned on the basis of the geographic sequence of each State within
 each census division; the first digit of the code is the code for the
 respective division. Puerto Rico, the Virgin Islands, and the outlying
 areas of the Pacific are assigned "0" as the division code. Each
 State and equivalent area also is assigned the two-letter FIPS/United
 States Postal Service (USPS) code.

 In 12 selected States (Connecticut, Maine, Massachusetts, Michigan,
 Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode
 Island, Vermont, and Wisconsin), the minor civil divisions also serve
 as general-purpose local governments. The Census Bureau presents data
 for these minor civil divisions in all data products in which it
 provides data for places.

 Tiger

 TIGER is an acronym for the new digital (computer-readable) geographic data
 base that automates the mapping and related geographic activities required
 to support the Census Bureau's census and survey programs. The Census
 Bureau developed the Topologically Integrated Geographic Encoding and
 Referencing (TIGER) System to automate the geographic support processes
 needed to meet the major geographic needs of the 1990 census: producing the
 cartographic products to support data collection and map publication,
 providing the geographic structure for tabulation and publication of the
 collected data, assigning residential and employer addresses to their
 geographic location and relating those locations to the Census Bureau's
 geographic units, and so forth. The content of the TIGER data base is made
 available to the public through a variety of "TIGER Extract" files that may
 be obtained from the Data User Services Division, U.S. Bureau of the
 Census, Washington, DC 20233.

 United States

 The United States comprises the 50 States and the District of
 Columbia. In addition, the Census Bureau treats the outlying areas as
 statistical equivalents of States for the 1990 census. The outlying
 areas include American Samoa, Guam, the Northern Mariana Islands,
 Palau, Puerto Rico, and the Virgin Islands of the United States.


 Urban and Rural

 Description

 The Census Bureau defines "urban" for the 1990 census as comprising all
 territory, population, and housing units in urbanized areas and in places
 of 2,500 or more persons outside urbanized areas.  More specifically,
 "urban" consists of territory, persons, and housing units in:

 1.  Places of 2,500 or more persons incorporated as cities, villages,
     boroughs (except in Alaska and New York), and towns (except in the six
     New England States, New York, and Wisconsin), but excluding the rural
     portions of "extended cities."

 2.  Census designated places of 2,500 or more persons.

 3.  Other territory, incorporated or unincorporated, included in urbanized
     areas.

 Territory, population, and housing units not classified as urban constitute
 "rural." In the 100-percent data products, "rural" is divided into "places
 of less than 2,500" and "not in places." The "not in places" category
 comprises "rural" outside incorporated and census designated places and the
 rural portions of extended cities. In many data products, the term "other
 rural" is used; "other rural" is a residual category specific to the
 classification of the rural in each data product.

 In the sample data products, rural population and housing units are
 subdivided into "rural farm" and "rural nonfarm." "Rural farm" comprises
 all rural households and housing units on farms (places from which $1,000
 or more of agricultural products were sold in 1989); "rural nonfarm"
 comprises the remaining rural.

 The urban and rural classification cuts across the other hierarchies;
 for example, there is generally both urban and rural territory within
 both metropolitan and nonmetropolitan areas.

 In censuses prior to 1950, "urban" comprised all territory,
 persons, and housing units in incorporated places of 2,500 or more
 persons, and in areas (usually minor civil divisions) classified as
 urban under special rules relating to population size and density. The
 definition of urban that restricted itself to incorporated places
 having 2,500 or more persons excluded many large, densely settled areas
 merely because they were not incorporated. Prior to the 1950 census,
 the Census Bureau attempted to avoid some of the more obvious omissions
 by classifying selected areas as "urban under special rules."
 Even with these rules, however, many large, closely built-up areas were
 excluded from the urban category.

 To improve its measure of urban territory, population, and housing
 units, the Census Bureau adopted the concept of the urbanized area and
 delineated boundaries for unincorporated places (now, census designated
 places) for the 1950 census. Urban was defined as territory, persons,
 and housing units in urbanized areas and, outside urbanized areas, in
 all places, incorporated or unincorporated, that had 2,500 or more
 persons. With the following three exceptions, the 1950 census
 definition of urban has continued substantially unchanged. First, in
 the 1960 census (but not in the 1970, 1980, or 1990 censuses), certain
 towns in the New England States, townships in New Jersey and
 Pennsylvania, and Arlington County, Virginia, were designated as urban.
 However, most of these "special rule" areas would have been
 classified as urban anyway because they were included in an urbanized
 area or in an unincorporated place of 2,500 or more persons. Second,
 "extended cities" were identified for the 1970, 1980, and 1990
 censuses. Extended cities primarily affect the figures for urban and
 rural territory (area), but have very little effect on the urban and
 rural population and housing units at the national and State levels--
 although for some individual counties and urbanized areas, the effects
 have been more evident. Third, changes since the 1970 census in the
 criteria for defining urbanized areas have permitted these areas to be
 defined around smaller centers.

 Documentation of the urbanized area and extended city criteria is
 available from the Chief, Geography Division, U.S. Bureau of the
 Census, Washington, DC 20233.

 Extended City

 Since the 1960 census, there has been a trend in some States toward
 the extension of city boundaries to include territory that is
 essentially rural in character. The classification of all the
 population and living quarters of such places as urban would include in
 the urban designation territory, persons, and housing units whose
 environment is primarily rural. For the 1970, 1980, and 1990 censuses,
 the Census Bureau identified as rural such territory and its population
 and housing units for each extended city whose closely settled area was
 located in an urbanized area. For the 1990 census, this classification
 also has been applied to certain places outside urbanized areas.

 In summary presentations by size of place, the urban portion of an
 extended city is classified by the population of the entire place; the
 rural portion is included in "other rural."


 Urbanized Area

 Description

 The Census Bureau delineates urbanized areas (UA's) to provide a
 better separation of urban and rural territory, population, and housing
 in the vicinity of large places. A UA comprises one or more places
 ("central place") and the adjacent densely settled surrounding
 territory ("urban fringe") that together have a minimum of 50,000
 persons. The urban fringe generally consists of contiguous territory
 having a density of least 1,000 persons per square mile. The urban
 fringe also includes outlying territory of such density if it was
 connected to the core of the contiguous area by road and is within 1
 1/2 road miles of that core, or within 5 road miles of the core but
 separated by water or other undevelopable territory. Other territory
 with a population density of fewer than 1,000 people per square mile is
 included in the urban fringe if it eliminates an enclave or closes an
 indentation in the boundary of the urbanized area. The population
 density is determined by (1) outside of a place, one or more contiguous
 census blocks with a population density of at least 1,000 persons per
 square mile or (2) inclusion of a place containing census blocks that
 have at least 50 percent of the population of the place and a density
 of at least 1,000 persons per square mile. The complete criteria are
 available from the Chief, Geography Division, U.S. Bureau of the
 Census, Washington, DC 20233.

 Urbanized Area Central Place

 One or more central places function as the dominant centers of each
 UA. The identification of a UA central place permits the comparison of
 this dominant center with the remaining territory in the UA. There is
 no limit on the number of central places, and not all central places
 are necessarily included in the UA title. UA central places include:

 1.  Each place entirely (or partially, if the place is an extended
     city) within the UA that is a central city of a metropolitan area (MA).

 2.  If the UA does not contain an MA central city or is located outside
     of an MA, the central place(s) is determined by population size.

 Urbanized Area Title and Code

 The title of a UA identifies those places that are most important
 within the UA; it links the UA to the encompassing MA, where
 appropriate. If a single MA includes most of the UA, the title and code
 of the UA generally are the same as the title and code of the MA. If
 the UA is not mostly included in a single MA, if it does not include
 any place that is a central city of the encompassing MA, or if it is
 not located in an MA, the Census Bureau uses the population size of the
 included places, with a preference for incorporated places, to
 determine the UA title. The name of each State in which the UA is
 located also is in each UA title.

 The numeric code used to identify each UA is the same as the code for
 the mostly encompassing MA (including CMSA and PMSA). If MA title
 cities represent multiple UA's, or the UA title city does not
 correspond to the first name of an MA title, the Census Bureau assigns
 a code based on the alphabetical sequence of the UA title in
 relationship to the other UA and MA titles.

 Voting District (VTD)

 A voting district (VTD) is any of a variety of types of areas (for
 example, election districts, precincts, wards, legislative districts)
 established by State and local governments for purposes of elections.
 For census purposes, each State participating in Phase 2 of the 1990
 Census Redistricting Data Program outlined the boundaries of VTD's
 around groups of whole census blocks on census maps. The entities
 identified as VTD's are not necessarily those legally or currently
 established. Also, to meet the "whole block" criterion, a State
 may have had to adjust VTD boundaries to nearby block boundaries.
 Therefore, the VTD's shown on the 1990 census tapes, listings, and maps
 may not represent the actual VTD's in effect at the time of the census.
 In the 1980 census, VTD's were referred to as "election precincts."

 Each VTD is assigned a four-character alphanumeric code that is unique
 within each county. The code "ZZZZ" is assigned to nonparticipating areas;
 the Census Bureau reports data for areas coded "ZZZZ."

 Zip Code(R)

 ZIP Codes are administrative units established by the United States
 Postal Service (USPS) for the distribution of mail. ZIP Codes serve
 addresses for the most efficient delivery of mail, and therefore
 generally do not respect political or census statistical area
 boundaries. ZIP Codes usually do not have clearly identifiable
 boundaries, often serve a continually changing area, are changed
 periodically to meet postal requirements, and do not cover all the land
 area of the United States. ZIP Codes are identified by five-digit codes
 assigned by the USPS. The first three digits identify a major city or
 sectional distribution center, and the last two digits generally
 signify a specific post office's delivery area or point. For the 1990
 census, ZIP Code data are tabulated for the five-digit codes in STF 3B.

 On computer--readable files, area measurements are shown to six
 decimal places; the decimal point is implied.

 Population Characteristics

 Age

 The data on age were derived from answers to questionnaire item 5,
 which was asked of all persons. The age classification is based on the
 age of the person in completed years as of April 1, 1990. The age
 response in question 5a was normally used to represent a person's age.
 However, when the age response was unacceptable or unavailable, a
 person's age was derived from an acceptable year of birth response in
 question 5b.

 Data on age are used to determine the applicability of other questions
 for a person and to classify other characteristics in census tabulations.
 Age data are needed to interpret most social and economic characteristics
 used to plan and examine many programs and policies.  Therefore, age is
 tabulated by single years of age and by many different groupings, such as
 5-year age groups.

 Some tabulations are shown by the age of the householder. These data
 were derived from the age responses for each householder. (For more
 information on householder, see the discussion under "Household Type
 and Relationship.")

 Median Age--This measure divides the age distribution into two equal
 parts:  one-half of the cases falling below the median value and one-half
 above the value. Generally, median age is computed on the basis of more
 detailed age intervals than are shown in some census publications;
 thus, a median based on a less detailed distribution may differ
 slightly from a corresponding median for the same population based on a
 more detailed distribution. (For more information on medians, see the
 discussion under "Derived Measures.")

 Limitation of the Data--  Counts in 1970 and 1980 for persons 100 years old
 and over were substantially overstated. Improvements were made in the
 questionnaire design, in the allocation procedures, and to the respondent
 instruction guide to attempt to minimize this problem in 1990.

 Review of detailed 1990 information indicated that respondents tended
 to provide their age as of the date of completion of the questionnaire,
 not their age as of April 1, 1990. In addition, there may have been a
 tendency for respondents to round their age up if they were close to
 having a birthday. It is likely that approximately 10 percent of
 persons in most age groups are actually 1 year younger. For most single
 years of age, the misstatements are largely offsetting. The problem is
 most pronounced at age 0 because persons lost to age 1 may not have
 been fully offset by the inclusion of babies born after April 1, 1990
 and because there may have been more rounding up to age 1 to avoid
 reporting age as 0 years. (Age in completed months was not collected
 for infants under age 1.)

 The reporting of age 1 year older than age on April 1, 1990 is likely
 to have been greater in areas where the census data were collected
 later in 1990. The magnitude of this problem was much less in the three
 previous censuses where age was typically derived from respondent data
 on year of birth and quarter of birth. (For more information on the
 design of the age question, see the section below that discusses
 "Comparability.")

 Comparability--  Age data have been collected in every census. For the
 first time since 1950, the 1990 data are not available by quarter year of
 age. This change was made so that coded information could be obtained for
 both age and year of birth. In each census since 1940, the age of a person
 was assigned when it was not reported. In censuses before 1940, with
 the exception of 1880, persons of unknown age were shown as a separate
 category. Since 1960, assignment of unknown age has been performed by a
 general procedure described as "imputation." The specific
 procedures for imputing age have been different in each census. (For
 more information on imputation, see Appendix C, Accuracy of the Data.)

 Group Quarters

 All persons not living in households are classified by the Census
 Bureau as living in group quarters. Two general categories of persons
 in group quarters are recognized: (1) institutionalized persons and (2)
 other persons in group quarters (also referred to as
 "noninstitutional group quarters").

 Institutionalized Persons--Includes persons under formally authorized,
 supervised care or custody in institutions at the time of enumeration. Such
 persons are classified as "patients or inmates" of an institution
 regardless of the availability of nursing or medical care, the length of
 stay, or the number of persons in the institution. Generally,
 institutionalized persons are restricted to the institutional buildings and
 grounds (or must have passes or escorts to leave) and thus have limited
 interaction with the surrounding community. Also, they are generally under
 the care of trained staff who have responsibility for their safekeeping and
 supervision.

 Type of Institution--The type of institution was determined as part of
 census enumeration activities. For institutions which specialize in only
 one specific type of service, all patients or inmates were given the same
 classification.  For institutions which had multiple types of major
 services (usually general hospitals and Veterans' Administration
 hospitals), patients were classified according to selected types of wards.
 For example, in psychiatric wards of hospitals, patients were classified in
 "mental (psychiatric) hospitals"; in hospital wards for persons with
 chronic diseases, patients were classified in "hospitals for the
 chronically ill." Each patient or inmate was classified in only one type of
 institution. Institutions include the following types:

   Correctional Institutions--Includes prisons, federal
   detention centers, military stockades and jails, police lockups,
   halfway houses, local jails, and other confinement facilities,
   including work farms.

     Prisons--Where persons convicted of crimes serve their
     sentences. In some census products, the prisons are classified by two
     types of control:  (1) "Federal" (operated by the Bureau of Prisons of
     the Department of Justice) and (2) "State." Residents who are
     criminally insane were classified on the basis of where they resided at
     the time of enumeration:  (1) in institutions (or hospital wards)
     operated by departments of correction or similar agencies; or (2) in
     institutions operated by departments of mental health or similar
     agencies.

     Federal Detention Centers--Operated by the Immigration and
     Naturalization Service (INS) and the Bureau of Prisons. These
     facilities include detention centers used by the Park Police; Bureau of
     Indian Affairs Detention Centers; INS Centers, such as the INS Federal
     Alien Detention Facility; INS Processing Centers; and INS Contract
     Detention Centers used to detain aliens under exclusion or deportation
     proceedings, as well as those aliens who have not been placed into
     proceedings, such as custodial required departures; and INS Detention
     Centers operated within local jails, and State and Federal prisons.

     Military Stockades, Jails--Operated by military police and used to hold
     persons awaiting trial or convicted of violating military laws.

     Local Jails and Other Confinement Facilities--Includes facilities
     operated by counties and cities that primarily hold persons beyond
     arraignment, usually for more than 48 hours. Also included in this
     category are work farms used to hold persons awaiting trial or serving
     time on relatively short sentences and jails run by private businesses
     under contract for local governments (but not by State governments).

     Police Lockups--Temporary-holding facilities operated by county and
     city police that hold persons for 48 hours or less only if they have
     not been formally charged in court.

     Halfway Houses--Operated for correctional purposes and include
     probation and restitution centers, pre-release centers, and
     community-residential centers.

     Other Types of Correctional Institutions--Privately operated
     correctional facilities and correctional facilities specifically for
     alcohol/drug abuse.

   Nursing Homes--Comprises a heterogeneous group of places. The majority of
   patients are elderly, although persons who require nursing care because
   of chronic physical conditions may be found in these homes regardless of
   their age. Included in this category are skilled-nursing facilities,
   intermediate-care facilities, long-term care rooms in wards or buildings
   on the grounds of hospitals, or long-term care rooms/nursing wings in
   congregate housing facilities.  Also included are nursing, convalescent,
   and rest homes, such as soldiers', sailors', veterans', and fraternal or
   religious homes for the aged, with or without nursing care. In some
   census products, nursing homes are classified by type of ownership as
   "Federal," "State," "Private not-for-profit," and "Private for profit."

   Mental (Psychiatric) Hospitals--Includes hospitals or wards for the
   criminally insane not operated by a prison, and psychiatric wards of
   general hospitals and veterans' hospitals.  Patients receive supervised
   medical/nursing care from formally-trained staff. In some census
   products, mental hospitals are classified by type of ownership as
   "Federal," "State or local," "Private," and "Ownership not known."

   Hospitals for Chronically Ill--Includes hospitals for patients who
   require long-term care, including those in military hospitals and wards
   for the chronically ill located on military bases; or other hospitals or
   wards for the chronically ill, which include tuberculosis hospitals or
   wards, wards in general and Veterans' Administration hospitals for the
   chronically ill, neurological wards, hospices, wards for patients with
   Hansen's Disease (leprosy) and other incurable diseases, and other
   unspecified wards for the chronically ill. Patients who had no usual home
   elsewhere were enumerated as part of the institutional population in the
   wards of general and military hospitals. Most hospital patients are at
   the hospital temporarily and were enumerated at their usual place of
   residence. (For more information, see "Wards in General and Military
   Hospitals for Patients Who Have No Usual Home Elsewhere.")

   Schools, Hospitals, or Wards for the Mentally Retarded--Includes those
   institutions such as wards in hospitals for the mentally retarded, and
   intermediate-care facilities for the mentally retarded that provide
   supervised medical/nursing care from formally-trained staff. In some
   census products, this category is classified by type of ownership as
   "Federal," "State or local," "Private," and "Ownership not known."

   Schools, Hospitals, or Wards for the Physically Handicapped--Includes
   three types of institutions: institutions for the blind, those for the
   deaf, and orthopedic wards and institutions for the physically
   handicapped.  Institutions for persons with speech problems are
   classified with "institutions for the deaf." The category "orthopedic
   wards and institutions for the physically handicapped" includes those
   institutions providing relatively long-term care to accident victims, and
   to persons with polio, cerebral palsy, and muscular dystrophy. In some
   census products, this category is classified by type of ownership as
   "Public," "Private," and "Ownership not known."

   Hospitals, and Wards for Drug/Alcohol Abuse--Includes hospitals, and
   hospital wards in psychiatric and general hospitals.  These facilities
   are equipped medically and designed for the diagnosis and treatment of
   medical or psychiatric illnesses associated with alcohol or drug abuse.
   Patients receive supervised medical care from formally-trained staff.

   Wards in General and Military Hospitals for Patients Who Have No Usual
   Home Elsewhere--Includes maternity, neonatal, pediatric (including wards
   for boarder babies), military, and surgical wards of hospitals, and wards
   for infectious diseases.

   Juvenile Institutions--Includes homes, schools, and other institutions
   providing care for children (short- or long-term care). Juvenile
   institutions include the following types:

     Homes for Abused, Dependent, and Neglected Children--Includes
     orphanages and other institutions which provide long-term care (usually
     more than 30 days) for children. This category is classified in some
     census products by type of ownership as "Public" and "Private."

     Residential Treatment Centers--Includes those institutions which
     primarily serve children who, by clinical diagnosis, are moderately or
     seriously disturbed emotionally. Also, these institutions provide
     long-term treatment services, usually supervised or directed by a
     psychiatrist.

     Training Schools for Juvenile Delinquents--Includes residential
     training schools or homes, and industrial schools, camps, or farms for
     juvenile delinquents.

       Public Training Schools for Juvenile Delinquents--Usually operated by
       a State agency (for example, department of welfare, corrections, or a
       youth authority). Some are operated by county and city governments.
       These public training schools are specialized institutions serving
       delinquent children, generally between the ages of 10 and 17 years
       old, all of whom are committed by the courts.

       Private Training Schools--Operated under private auspices. Some of
       the children they serve are committed by the courts as delinquents.
       Others are referred by parents or social agencies because of
       delinquent behavior. One difference between private and public
       training schools is that, by their administrative policy, private
       schools have control over their selection and intake.

     Detention Centers--Includes institutions providing short-term care
     (usually 30 days or less) primarily for delinquent children pending
     disposition of their cases by a court. This category also covers
     diagnostic centers. In practice, such institutions may be caring for
     both delinquent and neglected children pending court disposition.

 Other Persons in Group Quarters (also referred to as "noninstitutional
 group quarters")--Includes all persons who live in group quarters other
 than institutions. Persons who live in the following living quarters are
 classified as "other persons in group quarters" when there are 10
 or more unrelated persons living in the unit; otherwise, these living
 quarters are classified as housing units.

   Rooming Houses--Includes persons residing in rooming and boarding houses
   and living in quarters with 10 or more unrelated persons.

   Group Homes--Includes "community-based homes" that provide care and
   supportive services. Such places include homes for the mentally ill,
   mentally retarded, and physically handicapped; drug/alcohol halfway
   houses; communes; and maternity homes for unwed mothers.

     Homes for the Mentally Ill--Includes community-based homes that provide
     care primarily for the mentally ill. In some data products, this
     category is classified by type of ownership as "Federal," "State,"
     "Private," and "Ownership not known." Homes which combine treatment of
     the physically handicapped with treatment of the mentally ill are
     counted as homes for the mentally ill.

     Homes for the Mentally Retarded--Includes community-based homes that
     provide care primarily for the mentally retarded. Homes which combine
     treatment of the physically handicapped with treatment of the mentally
     retarded are counted as homes for the mentally retarded.  This category
     is classified by type of ownership in some census products, as
     "Federal," "State," "Private," or "Ownership not known."

     Homes for the Physically Handicapped--Includes community-based homes
     for the blind, for the deaf, and other community-based homes for the
     physically handicapped. Persons with speech problems are classified
     with homes for the deaf. In some census products, this category is
     classified by type of ownership as "Public," "Private," or "Ownership
     not known."

     Homes or Halfway Houses for Drug/Alcohol Abuse--Includes persons with
     no usual home elsewhere in places that provide community-based care and
     supportive services to persons suffering from a drug/alcohol addiction
     and to recovering alcoholics and drug abusers. Places providing
     community-based care for drug and alcohol abusers include group homes,
     detoxification centers, quarterway houses (residential treatment
     facilities that work closely with accredited hospitals), halfway
     houses, and recovery homes for ambulatory, mentally competent
     recovering alcoholics and drug abusers who may be re-entering the work
     force.

     Maternity Homes for Unwed Mothers--Includes persons with no usual home
     elsewhere in places that provide domestic care for unwed mothers and
     their children. These homes may provide social services and post-natal
     care within the facility, or may make arrangements for women to receive
     such services in the community.  Nursing services are usually available
     in the facility.

     Other Group Homes--Includes persons with no usual home elsewhere in
     communes, foster care homes, and job corps centers with 10 or more
     unrelated persons. These types of places provide communal living
     quarters, generally for persons who have formed their own community in
     which they have common interests and often share or own property
     jointly.

   Religious Group Quarters--Includes, primarily, group quarters for nuns
   teaching in parochial schools and for priests living in rectories. It
   also includes other convents and monasteries, except those associated
   with a general hospital or an institution.

   College Quarters Off Campus--Includes privately-owned rooming and
   boarding houses off campus, if the place is reserved exclusively for
   occupancy by college students and if there are 10 or more unrelated
   persons. In census products, persons in this category are classified as
   living in a college dormitory.

 Persons residing in certain other types of living arrangements are
 classified as living in "noninstitutional group quarters"
 regardless of the number of people sharing the unit. These include
 persons residing in the following types of group quarters:

   College Dormitories--Includes college students in dormitories (provided
   the dormitory is restricted to students who do not have their families
   living with them), fraternity and sorority houses, and on-campus
   residential quarters used exclusively for those in religious orders who
   are attending college. Students in privately-owned rooming and boarding
   houses off campus are also included, if the place is reserved exclusively
   for occupancy by college-level students and if there are 10 or more
   unrelated persons.

   Military Quarters--Includes military personnel living in barracks and
   dormitories on base, transient quarters on base for temporary residents
   (both civilian and military), and military ships.  However, patients in
   military hospitals receiving treatment for chronic diseases or who have
   no usual home elsewhere, and persons being held in military stockades
   were included as part of the institutional population.

   Agriculture Workers' Dormitories--Includes persons in migratory farm
   workers' camps on farms, bunkhouses for ranch hands, and other
   dormitories on farms, such as those on "tree farms."

   Other Workers' Dormitories--Includes persons in logging camps,
   construction workers' camps, firehouse dormitories, job-training
   camps, energy enclaves (Alaska only), and nonfarm migratory workers'
   camps (for example, workers in mineral and mining camps).

   Emergency Shelters for Homeless Persons (with sleeping facilities) and
   Visible in Street Locations--Includes persons enumerated during the
   "Shelter-and-Street-Night" operation primarily on March 20-21, 1990.
   Enumerators were instructed not to ask if a person was "homeless." If a
   person was at one of the locations below on March 20/21, the person was
   counted as described below. (For more information on the
   "Shelter-and-Street-Night" operation, see Appendix D, Collection
   and Processing Procedures.) This category is divided into four
   classifications:

     Emergency Shelters for Homeless Persons (with sleeping
     facilities)--Includes persons who stayed overnight on March 20,
     1990, in permanent and temporary emergency housing, missions, hotels/
     motels, and flophouses charging $12 or less (excluding taxes) per
     night; Salvation Army shelters, hotels, and motels used
     entirely for homeless persons regardless of the nightly rate
     charged; rooms in hotels and motels used partially for the
     homeless; and similar places known to have persons who have no usual
     home elsewhere staying overnight. If not shown separately, shelters and
     group homes which provide temporary sleeping facilities for
     runaway, neglected, and homeless children are included in this category
     in data products.

     Shelters for Runaway, Neglected, and Homeless Children--Includes
     shelters/group homes which provide temporary sleeping facilities for
     juveniles.

     Visible in Street Locations--Includes street blocks and open public
     locations designated before census day by city and community officials
     as places where the homeless congregate at night.  All persons found at
     predesignated street sites from 2 a.m. to 4 a.m. and leaving abandoned
     or boarded-up buildings from 4 a.m. to 8 a.m. on March 21, 1990, were
     enumerated during "street" enumeration, except persons in uniform such
     as police and persons engaged in obvious money-making activities other
     than begging or panhandling. Enumerators were instructed not to ask if
     a person was "homeless."

     This cannot be considered a complete count of all persons living on the
     streets because those who were so well hidden that local people did not
     know where to find them were likely to have been missed as were persons
     moving about or in places not identified by local officials. It is also
     possible that persons with homes could have been included in the count
     of "visible in street locations" if they were present when the
     enumerator did the enumeration of a particular block.

     Predesignated street sites include street corners, parks, bridges,
     persons emerging from abandoned and boarded-up buildings, noncommercial
     campsites (tent cities), all-night movie theaters, all-night
     restaurants, emergency hospital waiting rooms, train stations,
     airports, bus depots, and subway stations.

     Shelters for Abused Women (Shelters Against Domestic Violence or Family
     Crisis Centers)--Includes community-based homes or shelters that
     provide domiciliary care for women who have sought shelter from family
     violence and who may have been physically abused.  Most shelters also
     provide care for children of abused women. These shelters may provide
     social services, meals, psychiatric treatment, and counseling. In some
     census products, "shelters for abused women" are included in the
     category "other noninstitutional group quarters."

   Dormitories for Nurses and Interns in General and Military Hospitals--
   Includes group quarters for nurses and other staff  members. It excludes
   patients.

   Crews of Maritime Vessels--Includes officers, crew members, and
   passengers of Maritime U.S. flag vessels. All ocean-going and Great Lakes
   ships are included.

   Staff Residents of Institutions--Includes staff residing in group
   quarters on institutional grounds who provide formally-authorized,
   supervised care or custody for the institutionalized population.

   Other Nonhousehold Living Situations--Includes persons enumerated with no
   usual home elsewhere during transient, or "T-Night" enumeration at
   YMCA's, YWCA's, youth hostels, commercial and government-run campgrounds,
   campgrounds at racetracks, fairs, and carnivals, and similar transient
   sites.

   Living Quarters for Victims of Natural Disasters--Includes living
   quarters for persons temporarily displaced by natural disasters.

 Limitation of the Data--Two types of errors can occur in the classification
 of "types of group quarters":

 1.  Misclassification of Group Quarters--During the 1990
     Special Place Prelist operation, the enumerator determined the type of
     group quarters associated with each special place in their assignment.
     The enumerator used the Alphabetical Group Quarters Code List and Index
     to the Alphabetical Group Quarters Code List to assign a two-digit code
     number followed by either an "I," for institutional, or an
     "N," for noninstitutional to each group quarters. In 1990,
     unacceptable group quarter codes were edited. (For more information on
     editing of unacceptable data, see Appendix C, Accuracy of the Data.)

 2.  No Classification (unknowns)--The imputation rate for type of
     institution was higher in 1980 (23.5 percent) than in 1970 (3.3
     percent). Improvements were made to the 1990 Alphabetical Group
     Quarters Code List; that is, the inclusion of more group quarters
     categories and an "Index to the Alphabetical Group Quarters Code
     List." (For more information on the allocation rates for Type of
     Institution, see the allocation rates in 1990 CP-1, General
     Population Characteristics.)

 In previous censuses, allocation rates for demographic characteristics
 (such as age, sex, race, and marital status) of the institutional
 population were similar to those for the total population. The allocation
 rates for sample characteristics such as school enrollment, highest grade
 completed, income, and veteran status for the institutional and
 noninstitutional group quarters population have been substantially higher
 than the population in households at least as far back as the 1960 census.
 The data, however, have historically presented a reasonable picture of the
 institutional and noninstitutional group quarters population.

 Shelter and Street Night (S-Night)--For the 1990 census "Shelter-and-
 Street-Night" operation, persons well-hidden, moving about, or in locations
 enumerators did not visit were likely to be missed. The number of people
 missed will never be known; thus, the 1990 census cannot be considered a
 definitive count of America's total homeless population. It does, however,
 give an idea of relative differences among areas of the country. Other
 components were counted as part of regular census procedures.

   The count of persons in shelters and visible on the street could have
 been affected by many factors. How much the factors affected the count
 can never be answered definitively, but some elements include:

 1.  How well enumerators were trained and how well they followed
     procedures.

 2.  How well the list of shelter and street locations given to the
     Census Bureau by the local government reflected the actual places that
     homeless persons stay at night.

 3.  Cities were encouraged to open temporary shelters for census night,
     and many did that and actively encouraged people to enter the shelters.
     Thus, people who may have been on the street otherwise were in shelters
     the night of March 20, so that the ratio of shelter-to-street
     population could be different than usual.

 4.  The weather, which was unusually cold in some parts of the country,
     could affect how likely people were to seek emergency shelter or to be
     more hidden than usual if they stayed outdoors.

 5.  The media occasionally interfered with the ability to do the count.

 6.  How homeless people perceived the census and whether they wanted to
     be counted or feared the census and hid from it.

 The Census Bureau conducted two assessments of Shelter and Street
 Night: (1) the quality of the lists of shelters used for the Shelter
 and Street Night operation; and (2) how well procedures were followed
 by census takers for the street count in parts of five cities (Chicago,
 Los Angeles, New York, New Orleans, and Phoenix). (Information about
 these two assessments is available from the Chief, Center for Survey
 Methods Research, Bureau of the Census, Washington, DC 20233.)

 Comparability--For the 1990 census, the definition of institutionalized
 persons was revised so that the definition of "care" only includes persons
 under organized medical or formally-authorized, supervised care or
 custody. As a result of this change to the institutional definition,
 maternity homes are classified as noninstitutional rather than
 institutional group quarters as in previous censuses. The following
 types of other group quarters are classified as institutional rather
 than noninstitutional group quarters: "halfway houses (operated for
 correctional purposes)" and "wards in general and military
 hospitals for patients who have no usual home elsewhere," which
 includes maternity, neonatal, pediatric, military, and surgical wards
 of hospitals, other-purpose wards of hospitals, and wards for infectious
 diseases. These changes should not significantly affect the comparability
 of data with earlier censuses because of the relatively small number of
 persons involved.

 As in 1980, 10 or more unrelated persons living together were
 classified as living in noninstitutional group quarters. In 1970, the
 criteria was six or more unrelated persons.

 Several changes also have occurred in the identification of specific
 types of group quarters. For the first time, the 1990 census identifies
 separately the following types of correctional institutions: persons in
 halfway houses (operated for correctional purposes), military stockades
 and jails, and police lockups. In 1990, tuberculosis hospitals or wards
 are included with hospitals for the chronically ill; in 1980, they were
 shown separately. For 1990, the noninstitutional group quarters
 category, "Group homes" is further classified as: group homes for
 drug/alcohol abuse; maternity homes (for unwed mothers), group homes
 for the mentally ill, group homes for the mentally retarded, and group
 homes for the physically handicapped. Persons living in communes,
 foster-care homes, and job corps centers are classified with "Other group
 homes" only if 10 or more unrelated persons share the unit; otherwise, they
 are classified as housing units.

 In 1990, workers' dormitories were classified as group quarters
 regardless of the number of persons sharing the dorm. In 1980, 10 or
 more unrelated persons had to share the dorm for it to be classified as
 a group quarters. In 1960, data on persons in military barracks were
 shown only for men. In subsequent censuses, they include both men and
 women.

 In 1990 census data products, the phrase "inmates of institutions" was
 changed to "institutionalized persons."  Also, persons living in
 noninstitutional group quarters were referred to as "other persons in group
 quarters," and the phrase "staff residents" was used for staff living in
 institutions.

 In 1990, there are additional institutional categories and noninstitutional
 group quarters categories compared with the 1980
 census. The institutional categories added include "hospitals and
 wards for drug/alcohol abuse" and "military hospitals for the
 chronically ill." The noninstitutional group quarters categories
 added include emergency shelters for homeless persons; shelters for
 runaway, neglected, and homeless children; shelters for abused women;
 and visible in street locations. Each of these noninstitutional group
 quarters categories was enumerated on March 20-21, 1990, during the
 "Shelter and Street Night" operation. (For more information on
 the "Shelter-and-Street-Night" operation, see Appendix D,
 Collection and Processing Procedures.)

 Hispanic Origin

 The data on Spanish/Hispanic origin were derived from answers to
 questionnaire item 7, which was asked of all persons. Persons of
 Hispanic origin are those who classified themselves in one of the
 specific Hispanic origin categories listed on the questionnaire--"Mexican,"
 "Puerto Rican," or "Cuban"--as well as those who indicated that they were
 of "other Spanish/Hispanic" origin. Persons of "Other
 Spanish/Hispanic" origin are those whose origins are from Spain, the
 Spanish-speaking countries of Central or South America, or the
 Dominican Republic, or they are persons of Hispanic origin identifying
 themselves generally as Spanish, Spanish-American, Hispanic, Hispano,
 Latino, and so on. Write-in responses to the "other
 Spanish/Hispanic" category were coded only for sample data.

 Origin can be viewed as the ancestry, nationality group, lineage, or
 country of birth of the person or the person's parents or ancestors
 before their arrival in the United States. Persons of Hispanic origin
 may be of any race.

 Some tabulations are shown by the Hispanic origin of the householder.
 In all cases where households, families, or occupied housing units are
 classified by Hispanic origin, the Hispanic origin of the householder
 is used. (See the discussion of householder under "Household Type
 and Relationship.")

 During direct interviews conducted by enumerators, if a person could
 not provide a single origin response, he or she was asked to select,
 based on self-identification, the group which best described his or her
 origin or descent. If a person could not provide a single group, the
 origin of the person's mother was used. If a single group could not be
 provided for the person's mother, the first origin reported by the
 person was used.

 If any household member failed to respond to the Spanish/Hispanic
 origin question, a response was assigned by the computer according to
 the reported entries of other household members by using specific rules
 of precedence of household relationship. In the processing of sample
 questionnaires, responses to other questions on the questionnaire, such
 as ancestry and place of birth, were used to assign an origin before
 any reference was made to the origin reported by other household
 members. If an origin was not entered for any household member, an
 origin was assigned from another household according to the race of the
 householder. This procedure is a variation of the general imputation
 process described in Appendix C, Accuracy of the Data.

 Comparability--There may be differences between the total Hispanic origin
 population based on 100-percent tabulations and sample tabulations. Such
 differences are the result of sampling variability, nonsampling error,
 and more extensive edit procedures for the Spanish/Hispanic origin
 item on the sample questionnaires. (For more information on sampling
 variability and nonsampling error, see Appendix C, Accuracy of the
 Data.)

 The 1990 data on Hispanic origin are generally comparable with those
 for the 1980 census. However, there are some differences in the format
 of the Hispanic origin question between the two censuses. For 1990, the
 word "descent" was deleted from the 1980 wording. In addition,
 the term "Mexican-Amer." used in 1980 was shortened further to
 "Mexican-Am." to reduce misreporting (of "American") in this category
 detected in the 1980 census. Finally, the 1990 question allowed those who
 reported as "other Spanish/Hispanic" to write in their specific Hispanic
 origin group.

 Misreporting in the "Mexican-Amer." category of the 1980 census
 item on Spanish/Hispanic origin may affect the comparability of 1980
 and 1990 census data for persons of Hispanic origin for certain areas
 of the country. An evaluation of the 1980 census item on
 Spanish/Hispanic origin indicated that there was misreporting in the
 Mexican origin category by White and Black persons in certain areas.
 The study results showed evidence that the misreporting occurred in the
 South (excluding Texas), the Northeast (excluding the New York City
 area), and a few States in the Midwest Region. Also, results based on
 available data suggest that the impact of possible misreporting of
 Mexican origin in the 1980 census was severe in those portions of the
 above-mentioned regions where the Hispanic origin population was
 generally sparse. However, national 1980 census data on the Mexican
 origin population or total Hispanic origin population at the national
 level was not seriously affected by the reporting problem. (For a more
 detailed discussion of the evaluation of the 1980 census
 Spanish/Hispanic origin item, see the 1980 census Supplementary
 Reports.)

 The 1990 and 1980 census data on the Hispanic population are not
 directly comparable with 1970 Spanish origin data because of a number
 of factors: (1) overall improvements in the 1980 and 1990 censuses, (2)
 better coverage of the population, (3) improved question designs, and
 (4) an effective public relations campaign by the Census Bureau with
 the assistance of national and community ethnic groups.

 Specific changes in question design between the 1980 and 1970 censuses
 included the placement of the category "No, not Spanish/Hispanic"
 as the first category in that question. (The corresponding category
 appeared last in the 1970 question.) Also, the 1970 category
 "Central or South American" was deleted because in 1970 some
 respondents misinterpreted the category; furthermore, the designations
 "Mexican-American" and "Chicano" were added to the Spanish/Hispanic origin
 question in 1980. In the 1970 census, the question on Spanish origin was
 asked of only a 5-percent sample of the population.


 Household Type and Relationship

 Household

 A household includes all the persons who occupy a housing unit. A
 housing unit is a house, an apartment, a mobile home, a group of rooms,
 or a single room that is occupied (or if vacant, is intended for
 occupancy) as separate living quarters. Separate living quarters are
 those in which the occupants live and eat separately from any other
 persons in the building and which have direct access from the outside
 of the building or through a common hall. The occupants may be a single
 family, one person living alone, two or more families living together,
 or any other group of related or unrelated persons who share living
 arrangements.

 In 100-percent tabulations, the count of households or householders
 always equals the count of occupied housing units. In sample
 tabulations, the numbers may differ as a result of the weighting
 process.

 Persons Per Household--A measure obtained by dividing the number of persons
 in households by the number of households (or householders). In cases where
 persons in households are cross-classified by race or Hispanic origin,
 persons in the household are classified by the race or Hispanic origin of
 the householder rather than the race or Hispanic origin of each individual.

 Relationship to Householder

 Householder--The data on relationship to householder were derived from
 answers to questionnaire item 2, which was asked of all persons in housing
 units.  One person in each household is designated as the householder. In
 most cases, this is the person, or one of the persons, in whose name the
 home is owned, being bought, or rented and who is listed in column 1 of
 the census questionnaire. If there is no such person in the household,
 any adult household member 15 years old and over could be designated as
 the householder.

 Households are classified by type according to the sex of the
 householder and the presence of relatives. Two types of householders
 are distinguished: a family householder and a nonfamily householder. A
 family householder is a householder living with one or more persons
 related to him or her by birth, marriage, or adoption. The householder
 and all persons in the household related to him or her are family
 members. A nonfamily householder is a householder living alone or with
 nonrelatives only.

 Spouse--Includes a person married to and living with a householder. This
 category includes persons in formal marriages, as well as persons in
 common-law marriages.

 The number of spouses is equal to the number of "married-couple
 families" or "married-couple households" in 100-percent
 tabulations. The number of spouses, however, is generally less than
 half of the number of "married persons with spouse present" in
 sample tabulations, since more than one married couple can live in a
 household, but only spouses of householders are specifically identified
 as "spouse." For sample tabulations, the number of "married
 persons with spouse present" includes married-couple subfamilies and
 married-couple families.

 Child--Includes a son or daughter by birth, a stepchild, or adopted child
 of the householder, regardless of the child's age or marital status. The
 category excludes sons-in-law, daughters-in-law, and foster children.

   Natural-Born or Adopted Son/Daughter--A son or daughter of the
   householder by birth, regardless of the age of the child. Also,
   this category includes sons or daughters of the householder by legal
   adoption, regardless of the age of the child. If the
   stepson/stepdaughter of the householder has been legally adopted by the
   householder, the child is still classified as a stepchild.

   Stepson/Stepdaughter--A son or daughter of the householder through
   marriage but not by birth, regardless of the age of the child. If the
   stepson/stepdaughter of the householder has been legally adopted by the
   householder, the child is still classified as a stepchild.

   Own Child--A never-married child under 18 years who is a son or daughter
   by birth, a stepchild, or an adopted child of the householder. In certain
   tabulations, own children are further classified as living with two
   parents or with one parent only. Own children of the householder living
   with two parents are by definition found only in married-couple families.

   In a subfamily, an "own child" is a never-married child under 18
   years of age who is a son, daughter, stepchild, or an adopted child of
   a mother in a mother-child subfamily, a father in a father-child
   subfamily, or either spouse in a married-couple subfamily.

 "Related children" in a family include own children and all other persons
 under 18 years of age in the household, regardless of marital status, who
 are related to the householder, except the spouse of the householder.
 Foster children are not included since they are not related to the
 householder.

 Other Relatives--In tabulations, includes any household member related to
 the householder by birth, marriage, or adoption, but not included
 specifically in another relationship category. In certain detailed
 tabulations, the following categories may be shown:

   Grandchild--The grandson or granddaughter of the householder.

   Brother/Sister--The brother or sister of the householder, including
   stepbrothers, stepsisters, and brothers and sisters by adoption.
   Brothers-in-law and sisters-in-law are included in the "Other relative"
   category on the questionnaire.

   Parent--The father or mother of the householder, including a stepparent
   or adoptive parent. Fathers-in-law and mothers-in-law are included in the
   "Other relative" category on the questionnaire.

   Other Relatives--Anyone not listed in a reported category above who is
   related to the householder by birth, marriage, or adoption (brother-in-
   law, grandparent, nephew, aunt, mother-in-law, daughter-in-law, cousin,
   and so forth).

 Nonrelatives--Includes any household member, including foster children not
 related to the householder by birth, marriage, or adoption. The following
 categories may be presented in more detailed tabulations:

   Roomer, Boarder, or Foster Child--Roomer, boarder, lodger, and foster
   children or foster adults of the householder.

   Housemate or Roommate--A person who is not related to the householder and
   who shares living quarters primarily in order to share expenses.

   Unmarried Partner--A person who is not related to the householder, who
   shares living quarters, and who has a close personal relationship with
   the householder.

   Other Nonrelatives--A person who is not related by birth, marriage, or
   adoption to the householder and who is not described by the categories
   given above.

 When relationship is not reported for an individual, it is imputed
 according to the responses for age, sex, and marital status for that
 person while maintaining consistency with responses for other
 individuals in the household. (For more information on imputation, see
 Appendix C, Accuracy of the Data.)

 Unrelated Individual

 An unrelated individual is: (1) a householder living alone or with
 nonrelatives only, (2) a household member who is not related to the
 householder, or (3) a person living in group quarters who is not an
 inmate of an institution.

 Family Type

 A family consists of a householder and one or more other persons
 living in the same household who are related to the householder by
 birth, marriage, or adoption. All persons in a household who are
 related to the householder are regarded as members of his or her
 family. A household can contain only one family for purposes of census
 tabulations. Not all households contain families since a household may
 comprise a group of unrelated persons or one person living alone.

 Families are classified by type as either a "married-
 couple family" or "other family" according to the sex of the
 householder and the presence of relatives. The data on family type are
 based on answers to questions on sex and relationship which were asked
 on a 100-percent basis.

   Married-Couple Family--A family in which the householder and his or her
   spouse are enumerated as members of the same household.

 Other Family:

   Male Householder, No Wife Present--A family with a male
   householder and no spouse of householder present.

   Female Householder, No Husband Present--A family with a
   female householder and no spouse of householder present.

 Persons Per Family--A measure obtained by dividing the number of persons in
 families by the total number of families (or family householders). In cases
 where the measure, "persons in family" or "persons per family" are
 cross-tabulated by race or Hispanic origin, the race or Hispanic origin
 refers to the householder rather than the race or Hispanic origin of
 each individual.

 Subfamily

 A subfamily is a married couple (husband and wife enumerated as
 members of the same household) with or without never-married children
 under 18 years old, or one parent with one or more never-married
 children under 18 years old, living in a household and related to, but
 not including, either the householder or the householder's spouse. The
 number of subfamilies is not included in the count of families, since
 subfamily members are counted as part of the householder's family.

 Subfamilies are defined during processing of sample data. In selected
 tabulations, subfamilies are further classified by type: married-couple
 subfamilies, with or without own children; mother-child subfamilies;
 and father-child subfamilies.

 Lone parents include people maintaining either one-
 parent families or one-parent subfamilies. Married couples include
 husbands and wives in both married-couple families and married-couple
 subfamilies.

 Unmarried-Partner Household

 An unmarried-partner household is a household other than a
 "married-couple household" that includes a householder and an
 "unmarried partner." An "unmarried partner" can be of the
 same sex or of the opposite sex of the householder. An "unmarried
 partner" in an "unmarried partner household" is an adult who
 is unrelated to the householder, but shares living quarters and has a
 close personal relationship with the householder.

 Unmarried-Couple Household

 An unmarried-couple household is composed of two unrelated adults of
 the opposite sex (one of whom is the householder) who share a housing
 unit with or without the presence of children under 15 years old.

 Foster Children

 Foster children are nonrelatives of the householder and are included
 in the category, "Roomer, boarder, or foster child" on the
 questionnaire. Foster children are identified as persons under 18 years
 old and living in households that have no nonrelatives 18 years old and
 over (who might be parents of the nonrelatives under 18).

 Stepfamily

 A stepfamily is a "married-couple family" with at least one
 stepchild of the householder present, where the householder is the
 husband.

 Comparability--The 1990 definition of a household is the same as that used
 in 1980.  The 1980 relationship category "Son/daughter" has been replaced
 by two categories, "Natural-born or adopted son/daughter" and
 "Stepson/stepdaughter." "Grandchild" has been added as a separate category.
 The 1980 nonrelative categories: "Roomer, boarder" and "Partner, roommate"
 have been replaced by the categories "Roomer, boarder, or foster child,"
 "Housemate, roommate," and "Unmarried partner." The 1980 nonrelative
 category "Paid employee" has been dropped.

 Marital Status

 The data on marital status were derived from answers to questionnaire item
 6, which was asked of all persons. The marital status classification refers
 to the status at the time of enumeration.  Data on marital status are
 tabulated only for persons 15 years old and over.

 All persons were asked whether they were "now married," "widowed,"
 "divorced," "separated," or "never married." Couples who live together
 (unmarried persons, persons in common-law marriages) were allowed to report
 the marital status they considered the most appropriate.

 Never Married--Includes all persons who have never been married, including
 persons whose only marriage(s) was annulled.

 Ever Married--Includes persons married at the time of enumeration
 (including those separated), widowed, or divorced.

 Now Married, Except Separated--Includes persons whose current marriage has
 not ended through widowhood, divorce, or separation (regardless of previous
 marital history). The category may also include couples who live together
 or persons in common-law marriages if they consider this category the most
 appropriate. In certain tabulations, currently married persons are
 further classified as "spouse present" or "spouse absent."

 Separated--Includes persons legally separated or otherwise absent from
 their spouse because of marital discord. Included are persons who have been
 deserted or who have parted because they no longer want to live together
 but who have not obtained a divorce.

 Widowed--Includes widows and widowers who have not remarried.

 Divorced--Includes persons who are legally divorced and who have not
 remarried.

 In selected sample tabulations, data for married and separated persons are
 reorganized and combined with information on the presence of the spouse in
 the same household.

 Now Married--All persons whose current marriage has not ended by widowhood
 or divorce. This category includes persons defined above as "separated."

   Spouse Present--Married persons whose wife or husband was enumerated as a
   member of the same household, including those whose spouse may have been
   temporarily absent for such reasons as travel or hospitalization.

   Spouse Absent--Married persons whose wife or husband was not enumerated
   as a member of the same household. This category also includes all
   married persons living in group quarters.

   Separated--Defined above.

   Spouse Absent, Other--Married persons whose wife or husband was not
   enumerated as a member of the same household, excluding separated.
   Included is any person whose spouse was employed and living away from
   home or in an institution or absent in the Armed Forces.

 Differences between the number of currently married males and the number of
 currently married females occur because of reporting differences and
 because some husbands and wives have their usual residence in different
 areas. In sample tabulations, these differences can also occur because
 different weights are applied to the individual's data. Any differences
 between the number of "now married, spouse present" males and females are
 due solely to sample weighting. By definition, the numbers would be the
 same.

 When marital status was not reported, it was imputed according to the
 relationship to the householder and sex and age of the person. (For
 more information on imputation, see Appendix C, Accuracy of the Data.)

 Comparability--The 1990 marital status definitions are the same as those
 used in 1980 with the exception of the term "never married" which replaces
 the term "single" in tabulations. A general marital status question
 has been asked in every census since 1880.

 Race

 The data on race were derived from answers to questionnaire item 4, which
 was asked of all persons. The concept of race as used by the Census Bureau
 reflects self-identification; it does not denote any clear-cut scientific
 definition of biological stock. The data for race represent self-
 classification by people according to the race with which they most closely
 identify. Furthermore, it is recognized that the categories of the race
 item include both racial and national origin or socio-cultural groups.

 During direct interviews conducted by enumerators, if a person could
 not provide a single response to the race question, he or she was asked
 to select, based on self-identification, the group which best described
 his or her racial identity. If a person could not provide a single race
 response, the race of the mother was used. If a single race response
 could not be provided for the person's mother, the first race reported
 by the person was used. In all cases where occupied housing units,
 households, or families are classified by race, the race of the
 householder was used.

 The racial classification used by the Census Bureau generally adheres
 to the guidelines in Federal Statistical Directive No. 15, issued by
 the Office of Management and Budget, which provides standards on ethnic
 and racial categories for statistical reporting to be used by
 all Federal agencies. The racial categories used in the 1990 census
 data products are provided below.

 White--Includes persons who indicated their race as "White" or reported
 entries such as Canadian, German, Italian, Lebanese, Near Easterner,
 Arab, or Polish.

 Black--Includes persons who indicated their race as "Black or Negro" or
 reported entries such as African American, Afro-American, Black Puerto
 Rican, Jamaican, Nigerian, West Indian, or Haitian.

 American Indian, Eskimo, or Aleut--Includes persons who classified
 themselves as such in one of the specific race categories identified below.

   American Indian--Includes persons who indicated their race as "American
   Indian," entered the name of an Indian tribe, or reported such entries as
   Canadian Indian, French-American Indian, or Spanish-American Indian.

   American Indian Tribe--Persons who identified themselves as American
   Indian were asked to report their enrolled or principal tribe. Therefore,
   tribal data in tabulations reflect the written tribal entries reported on
   the questionnaires. Some of the entries (for example, Iroquois, Sioux,
   Colorado River, and Flathead) represent nations or reservations.

   The information on tribe is based on self-identification and therefore
   does not reflect any designation of Federally- or State-recognized
   tribe. Information on American Indian tribes is presented in summary
   tape files and special data products. The information is derived from
   the American Indian Detailed Tribal Classification List for the 1990
   census. The classification list represents all tribes, bands, and clans
   that had a specified number of American Indians reported on the census
   questionnaire.

   Eskimo--Includes persons who indicated their race as "Eskimo" or reported
   entries such as Arctic Slope, Inupiat, and Yupik.

   Aleut--Includes persons who indicated their race as "Aleut" or reported
   entries such as Alutiiq, Egegik, and Pribilovian.

 Asian or Pacific Islander--Includes persons who reported in one of the
 Asian or Pacific Islander groups listed on the questionnaire or who
 provided write-in responses such as Thai, Nepali, or Tongan. A more
 detailed listing of the groups comprising the Asian or Pacific Islander
 population is presented in table A below. In some data products,
 information is presented separately for the Asian population and the
 Pacific Islander population.

 Asian--Includes "Chinese," "Filipino," "Japanese," "Asian Indian,"
 "Korean," "Vietnamese," and "Other Asian." In some tables, "Other Asian"
 may not be shown separately, but is included in the total Asian population.


   Chinese--Includes persons who indicated their race as "Chinese" or who
   identified themselves as Cantonese, Tibetan, or Chinese American. In
   standard census reports, persons who reported as "Taiwanese" or
   "Formosan" are included here with Chinese.  In special reports on the
   Asian or Pacific Islander population, information on persons who
   identified themselves as Taiwanese are shown separately.

   Filipino--Includes persons who indicated their race as "Filipino" or
   reported entries such as Philipino, Philippine, or Filipino American.

   Japanese--Includes persons who indicated their race as "Japanese" and
   persons who identified themselves as Nipponese or Japanese American.

   Asian Indian--Includes persons who indicated their race as "Asian Indian"
   and persons who identified themselves as Bengalese, Bharat, Dravidian,
   East Indian, or Goanese.

   Korean--Includes persons who indicated their race as "Korean" and persons
   who identified themselves as Korean American.

   Vietnamese--Includes persons who indicated their race as "Vietnamese" and
   persons who identified themselves as Vietnamese American.

   Cambodian--Includes persons who provided a write-in response such as
   Cambodian or Cambodia.

   Hmong--Includes persons who provided a write-in response such as Hmong,
   Laohmong, or Mong.

   Laotian--Includes persons who provided a write-in response such as
   Laotian, Laos, or Lao.

   Thai--Includes persons who provided a write-in response such as Thai,
   Thailand, or Siamese.

   Other Asian--Includes persons who provided a write-in response of
   Bangladeshi, Burmese, Indonesian, Pakistani, Sri Lankan, Amerasian, or
   Eurasian. See table A for other groups comprising "Other Asian."

 Pacific Islander--Includes persons who indicated their race as "Pacific
 Islander" by classifying themselves into one of the following race
 categories or identifying themselves as one of the Pacific Islander
 cultural groups of Polynesian, Micronesian, or Melanesian.

   Hawaiian--Includes persons who indicated their race as "Hawaiian" as well
   as persons who identified themselves as Part Hawaiian or Native Hawaiian.

   Samoan--Includes persons who indicated their race as "Samoan" or persons
   who identified themselves as American Samoan or Western Samoan.

   Guamanian--Includes persons who indicated their race as "Guamanian" or
   persons who identified themselves as Chamorro or Guam.

   Other Pacific Islander--Includes persons who provided a write-in response
   of a Pacific Islander group such as Tahitian, Northern Mariana Islander,
   Palauan, Fijian, or a cultural group such as Polynesian, Micronesian, or
   Melanesian. See table A for other groups comprising "Other Pacific
   Islander."

 Other Race--Includes all other persons not included in the "White,"
 "Black," "American Indian, Eskimo, or Aleut," and the "Asian or Pacific
 Islander" race categories described above.  Persons reporting in the
 "Other race" category and providing write-in entries such as multiracial,
 multiethnic, mixed, interracial, Wesort, or a Spanish/Hispanic origin
 group (such as Mexican, Cuban, or Puerto Rican) are included here.

 Written entries to three categories on the race item-- "Indian
 (Amer.)," "Other Asian or Pacific Islander (API)," and "Other race"--were
 reviewed, edited, and coded by subject matter specialists. (For more
 information on the coding operation, see the section below that discusses
 "Comparability.")

 The written entries under "Indian (Amer.)" and "Other Asian or
 Pacific Islander (API)" were reviewed and coded during 100-percent
 processing of the 1990 census questionnaires. A substantial portion of
 the entries for the "Other race" category also were reviewed,
 edited, and coded during the 100-percent processing. The remaining
 entries under "Other race" underwent review and coding during
 sample processing. Most of the written entries reviewed during sample
 processing were those indicating Hispanic origin such as Mexican,
 Cuban, or Puerto Rican.

 If the race entry for a member of a household was missing on the
 questionnaire, race was assigned based upon the reported entries of
 race by other household members using specific rules of precedence of
 household relationship. For example, if race was missing for the
 daughter of the householder, then the race of her mother (as female
 householder or female spouse) would be assigned. If there was no female
 householder or spouse in the household, the daughter would be assigned
 her father's (male householder) race. If race was not reported for
 anyone in the household, the race of a householder in a previously
 processed household was assigned. This procedure is a variation of the
 general imputation procedures described in Appendix C, Accuracy of the
 Data.

 Limitation of the Data--In the 1980 census, a relatively high proportion
 (20 percent) of American Indians did not report any tribal entry in the
 race item.  Evaluation of the pre-census tests indicated that changes made
 for the 1990 race item should improve the reporting of tribes in the rural
 areas (especially on reservations) for the 1990 census. The results for
 urban areas were inconclusive. Also, the precensus tests indicated that
 there may be overreporting of the Cherokee tribe. An evaluation of 1980
 census data showed overreporting of Cherokee in urban areas or areas
 where the number of American Indians was sparse.

 In the 1990 census, respondents sometimes did not fill in a circle or
 filled the "Other race" circle and wrote in a response, such as
 Arab, Polish, or African American in the shared write-in box for
 "Other race" and "Other API" responses. During the automated coding
 process, these responses were edited and assigned to the appropriate racial
 designation. Also, some Hispanic origin persons did not fill in a circle,
 but provided entries such as Mexican or Puerto Rican. These persons were
 classified in the "Other race" category during the coding and editing
 process. Since sample processing included additional editing, there may be
 some minor differences between sample data and 100-percent data.

 Comparability--Differences between the 1990 census and earlier censuses
 affect the comparability of data for certain racial groups and American
 Indian tribes. The 1990 census was the first census to undertake, on a
 100-percent basis, an automated review, edit, and coding operation for
 written responses to the race item. The automated coding system used in
 the 1990 census greatly reduced the potential for error associated with
 a clerical review. Specialists with a thorough knowledge of the race
 subject matter reviewed, edited, coded, and resolved inconsistent or
 incomplete responses. In the 1980 census, there was only a limited
 clerical review of the race responses on the 100-percent forms with a
 full clerical review conducted only on the sample questionnaires.

 Another major difference between the 1990 and preceding censuses is the
 handling of the write-in responses for the Asian or Pacific Islander
 populations. In addition to the nine Asian or Pacific Islander
 categories shown on the questionnaire under the spanner "Asian or
 Pacific Islander (API)," the 1990 census race item provided a new
 residual category, "Other API," for Asian or Pacific Islander
 persons who did not report in one of the listed Asian or Pacific
 Islander groups. During the coding operation, write-in responses for
 "Other API" were reviewed, coded, and assigned to the appropriate
 classification. For example, in 1990, a write-in entry of Laotian,
 Thai, or Javanese is classified as "Other Asian," while a
 write-in entry of Tongan or Fijian is classified as "Other Pacific
 Islander."

 ---------------------------------------------------------------------------

 (1)In some data products, specific groups listed under "Other Asian" or
 "Other Pacific Islander" are shown separately. Groups not shown are
 tabulated as "All other Asian" or "All other Pacific Islander,"
 respectively.

 (2)Includes entries such as Asian American, Asian, Asiatic, Amerasian, and
 Eurasian.

 (3)Polynesian, Micronesian, and Melanesian are Pacific Islander cultural
 groups.

 In the 1980 census, the nine Asian or Pacific Islander groups were
 also listed separately. However, persons not belonging to these nine
 groups wrote in their specific racial group under the "Other"
 race category. Persons with a written entry such as Laotian, Thai, or
 Tongan, were tabulated and published as "Other race" in the
 100-percent processing operation in 1980, but were reclassified as
 "Other Asian and Pacific Islander" in 1980 sample tabulations. In
 1980 special reports on the Asian or Pacific Islander populations, data
 were shown separately for "Other Asian" and "Other Pacific
 Islander."

 The 1970 questionnaire did not have separate race categories for Asian
 Indian, Vietnamese, Samoan, and Guamanian. These persons indicated
 their race in the "Other" category and later, through the editing
 process, were assigned to a specific group. For example, in 1970, Asian
 Indians were reclassified as "White," while Vietnamese,
 Guamanians, and Samoans were included in the "Other" category.

 Another difference between the 1990 and preceding censuses is the
 approach taken when persons of Spanish/Hispanic origin did not report
 in a specific race category but reported as "Other race" or
 "Other." These persons commonly provided a write-in entry such as
 Mexican, Venezuelan, or Latino. In the 1990 and 1980 censuses, these
 entries remained in the "Other race" or "Other" category,
 respectively. In the 1970 census, most of these persons were included
 in the "White" category.


 Sex

 The data on sex were derived from answers to questionnaire item 3,
 which was asked of all persons. For most cases in which sex was not
 reported, it was determined by the appropriate entry from the person's
 given name and household relationship. Otherwise, sex was imputed
 according to the relationship to the householder and the age and
 marital status of the person. For more information on imputation, see
 Appendix C, Accuracy of the Data.

 Sex Ratio--A measure derived by dividing the total number of males by the
 total number of females and multiplying by 100.

 Comparability--A question on the sex of individuals has been asked of the
 total population in every census.


 Housing Characteristics

 Living Quarters

 Living quarters are classified as either housing units or group
 quarters. (For more information, see discussion of "Group
 Quarters" under Population Characteristics.) Usually, living
 quarters are in structures intended for residential use (for example, a
 one-family home, apartment house, hotel or motel, boarding house, or
 mobile home). Living quarters also may be in structures intended for
 nonresidential use (for example, the rooms in a warehouse where a guard
 lives), as well as in places such as tents, vans, shelters for the
 homeless, dormitories, barracks, and old railroad cars.

 Housing Units--A housing unit is a house, an apartment, a mobile home or
 trailer, a group of rooms or a single room occupied as separate living
 quarters or, if vacant, intended for occupancy as separate living quarters.
 Separate living quarters are those in which the occupants live and eat
 separately from any other persons in the building and which have direct
 access from outside the building or through a common hall.

 The occupants may be a single family, one person living alone, two or
 more families living together, or any other group of related or
 unrelated persons who share living arrangements. For vacant units, the
 criteria of separateness and direct access are applied to the intended
 occupants whenever possible. If that information cannot be obtained,
 the criteria are applied to the previous occupants.

 Both occupied and vacant housing units are included in the housing unit
 inventory, except that recreational vehicles, boats, caves, tents,
 railroad cars, and the like are included only if they are occupied as
 someone's usual place of residence. Vacant mobile homes are included
 provided they are intended for occupancy on the site where they stand.
 Vacant mobile homes on dealers' sales lots, at the factory, or in
 storage yards are excluded from the housing inventory.

 If the living quarters contain 9 or more persons unrelated to the
 householder or person in charge (a total of 10 unrelated persons), they
 are classified as group quarters. If the living quarters contain eight
 or fewer persons unrelated to the householder or person in charge, they
 are classified as housing units.

 Occupied Housing Units--A housing unit is classified as occupied if it is
 the usual place of residence of the person or group of persons living in it
 at the time of enumeration, or if the occupants are only temporarily
 absent; that is, away on vacation. If all the persons staying in the unit
 at the time of the census have their usual place of residence elsewhere,
 the unit is classified as vacant. A household includes all the persons who
 occupy a housing unit as their usual place of residence. By definition, the
 count of occupied housing units for 100-percent tabulations is the same
 as the count of households or householders.

 Vacant Housing Units--A housing unit is vacant if no one is living in it at
 the time of enumeration, unless its occupants are only temporarily absent.
 Units temporarily occupied at the time of enumeration entirely by persons
 who have a usual residence elsewhere are also classified as vacant. (For
 more information, see discussion under "Usual Home Elsewhere.")

 New units not yet occupied are classified as vacant housing units if
 construction has reached a point where all exterior windows and doors
 are installed and final usable floors are in place. Vacant units are
 excluded if they are open to the elements; that is, the roof, walls,
 windows, and/or doors no longer protect the interior from the elements,
 or if there is positive evidence (such as a sign on the house or in the
 block) that the unit is condemned or is to be demolished. Also excluded
 are quarters being used entirely for nonresidential purposes, such as a
 store or an office, or quarters used for the storage of business
 supplies or inventory, machinery, or agricultural products.

 Hotels, Motels, Rooming Houses, Etc.--Occupied rooms or suites of rooms in
 hotels, motels, and similar places are classified as housing units only
 when occupied by permanent residents; for example, persons who consider the
 hotel as their usual place of residence or have no usual place of residence
 elsewhere.  Vacant rooms or suites of rooms are classified as housing units
 only in those hotels, motels, and similar places in which 75 percent or
 more of the accommodations are occupied by permanent residents.

 If any of the occupants in a rooming or boarding house live and eat
 separately from others in the building and have direct access, their
 quarters are classified as separate housing units.

 Staff Living Quarters--The living quarters occupied by staff personnel
 within any group quarters are separate housing units if they satisfy the
 housing unit criteria of separateness and direct access; otherwise, they
 are considered group quarters.

 Comparability--The first Census of Housing in 1940 established the
 "dwelling unit" concept. Although the term became "housing unit" and the
 definition has been modified slightly in succeeding censuses, the 1990
 definition is essentially comparable to previous censuses. There was no
 change in the housing unit definition between 1980 and 1990.

 Acreage

 The data on acreage were obtained from questionnaire item H5a, which
 was asked at all occupied and vacant one-family houses and mobile
 homes. The land may consist of more than one tract or plot. These
 tracts or plots are usually adjoining; however, they may be separated
 by a road or creek, or another piece of land. This question is used to
 exclude owner-occupied and renter-occupied one-family houses and mobile
 homes with 10 or more acres from certain statistics on financial
 characteristics.

 Comparability--The question on acreage is the same in 1970 and 1980 and was
 asked for the first time of mobile home occupants in the 1990 census.

 Boarded-Up Status

 Boarded-up status was obtained from questionnaire item C2 and was
 determined for all vacant units. Boarded-up units have windows and
 doors covered by wood, metal, or masonry to protect the interior and to
 prevent entry into the building. A single-unit structure, a unit in a
 multi-unit structure, or an entire multi-unit structure may be
 boarded-up in this way. For certain census data products, boarded-up
 units are shown only for units in the "Other vacant" category. A
 unit classified as "Usual home elsewhere" can never be boarded
 up. (For more information, see the discussion under "Usual Home
 Elsewhere.")

 Comparability--This item was first asked in the 1980 census and was shown
 only for year-round vacant housing units. In 1990, data are shown for all
 vacant housing units.

 Business on Property

 The data for business on property were obtained from questionnaire
 item H5b, which was asked at all occupied and vacant one-family houses
 and mobile homes. This question is used to exclude owner-occupied
 one-family and mobile home units with business or medical offices from
 certain statistics on financial characteristics.

 A business must be easily recognizable from the outside. It will
 usually have a separate outside entrance and have the appearance of a
 business, such as a grocery store, restaurant, or barbershop. It may be
 either attached to the house or mobile home or be located elsewhere on
 the property. Those housing units in which a room is used for business
 or professional purposes and have no recognizable alterations to the
 outside are not considered as having a business. Medical
 offices are considered businesses for tabulation purposes.

 Comparability--Data on business on property have been collected since 1940.

 Contract Rent

 The data on contract rent (also referred to as "rent asked"
 for vacant units) were obtained from questionnaire item H7a, which was
 asked at all occupied housing units that were rented for cash rent and
 all vacant housing units that were for rent at the time of enumeration.


 Housing units that are renter occupied without payment of cash rent are
 shown separately as "No cash rent" in census data products. The
 unit may be owned by friends or relatives who live elsewhere and who
 allow occupancy without charge. Rent-free houses or apartments may be
 provided to compensate caretakers, ministers, tenant farmers,
 sharecroppers, or others.

 Contract rent is the monthly rent agreed to or contracted for,
 regardless of any furnishings, utilities, fees, meals, or services that
 may be included. For vacant units, it is the monthly rent asked for the
 rental unit at the time of enumeration.

 If the contract rent includes rent for a business unit or for living
 quarters occupied by another household, the respondent was instructed
 to report that part of the rent estimated to be for his or her unit
 only. Respondents were asked to report rent only for the housing unit
 enumerated and to exclude any rent paid for additional units or for
 business premises.

 If a renter pays rent to the owner of a condominium or cooperative, and
 the condominium fee or cooperative carrying charge is also paid by the
 renter to the owner, the respondent was instructed to include the fee
 or carrying charge.

 If a renter receives payments from lodgers or roomers who are listed as
 members of the household, the respondent was instructed to report the
 rent without deduction for any payments received from the lodgers or
 roomers. The respondent was instructed to report the rent agreed to or
 contracted for even if paid by someone else such as friends or
 relatives living elsewhere, or a church or welfare agency.

 In some tabulations, contract rent is presented for all renter-occupied
 housing units, as well as specified renter-occupied and specified
 vacant-for-rent units. Specified renter-occupied and specified
 vacant-for-rent units exclude one-family houses on 10 or more acres.
 (For more information on rent, see the discussion under "Gross
 Rent" in census products containing sample data.)

 Median and Quartile Contract Rent--The median divides the rent distribution
 into two equal parts.  Quartiles divide the rent distribution into four
 equal parts. In computing median and quartile contract rent, units reported
 as "No cash rent" are excluded. Median and quartile rent calculations are
 rounded to the nearest dollar. (For more information on medians and
 quartiles, see the discussion under "Derived Measures.")

 Aggregate Contract Rent--To calculate aggregate contract rent, the amount
 assigned for the category "less than $80" is $50. The amount assigned to
 the category "$1,000 or more" is $1,250. (For more information on
 aggregates and means, see the discussion under "Derived Measures.")

 Comparability--Data on this item have been collected since 1940. For 1990,
 quartiles were added because the range of rents and values in the United
 States has increased in recent years. Upper and lower quartiles can be used
 to note large rent and value differences among various geographic areas.

 Duration of Vacancy

 The data for duration of vacancy (also referred to as "months
 vacant") were obtained from questionnaire item D, which was
 completed by census enumerators. The statistics on duration of vacancy
 refer to the length of time (in months and years) between the date the
 last occupants moved from the unit and the time of enumeration. The
 data, therefore, do not provide a direct measure of the total length of
 time units remain vacant.

 For newly constructed units which have never been occupied, the
 duration of vacancy is counted from the date construction was
 completed. For recently converted or merged units, the time is reported
 from the date conversion or merger was completed. Units occupied by an
 entire household with a usual home elsewhere are assigned to the
 "Less than 1 month" interval.

 Comparability--Similar data have been collected since 1960. In 1970 and
 1980, these data were shown only for year-round housing units. In 1990,
 these data are shown for all housing units.

 Meals Included in Rent

 The data on meals included in the rent were obtained from
 questionnaire item H7b, which was asked of all occupied housing units
 that were rented for cash and all vacant housing units that were for
 rent at the time of enumeration.

 The statistics on meals included in rent are presented for specified
 renter-occupied and specified vacant-for-
 rent units. Specified renter-occupied and specified vacant-
 for-rent units exclude one-family houses on 10 or more acres. (For more
 information, see the discussion under "Contract Rent.")

 Comparability--This is a new item in 1990. It is intended to measure
 "congregate" housing which is generally considered to be housing
 units where the rent includes meals and other services, such as
 transportation to shopping and recreation.

 Persons in Unit

 This item is based on the 100-percent count of persons in occupied
 housing units. All persons occupying the housing unit are counted,
 including the householder, occupants related to the householder, and
 lodgers, roomers, boarders, and so forth.

 The data on "persons in unit" show the number of housing units
 occupied by the specified number of persons. The phrase "persons in
 unit" is used for housing tabulations, "persons in households"
 for population items. Figures for "persons in unit" match those
 for "persons in household" for 100-percent data products. In
 sample products, they may differ because of the weighting process.

 Median Persons in Unit--In computing median persons in unit, a whole number
 is used as the midpoint of an interval; thus, a unit with 4 persons is
 treated as an interval ranging from 3.5 to 4.5 persons. Median persons is
 rounded to the nearest hundredth. (For more information on medians, see the
 discussion under "Derived Measures.")

 Persons in Occupied Housing Units--This is the total population minus those
 persons living in group quarters. "Persons per occupied housing unit" is
 computed by dividing the population living in housing units by the number
 of occupied housing units.

 Persons Per Room

 "Persons per room" is obtained by dividing the number of
 persons in each occupied housing unit by the number of rooms in the
 unit. Persons per room is rounded to the nearest hundredth. The figures
 shown refer, therefore, to the number of occupied housing units having
 the specified ratio of persons per room.

 Mean Persons Per Room--This is computed by dividing persons in housing
 units by the aggregate number of rooms. This is intended to provide a
 measure of utilization.  A higher mean may indicate a greater degree of
 utilization or crowding; a low mean may indicate under-utilization.
 (For more information on means, see the discussion under "Derived
 Measures.")

 Rooms

 The data on rooms were obtained from questionnaire item H3, which
 was asked at both occupied and vacant housing units. The statistics on
 rooms are in terms of the number of housing units with a specified
 number of rooms. The intent of this question is to count the number of
 whole rooms used for living purposes.

 For each unit, rooms include living rooms, dining rooms, kitchens,
 bedrooms, finished recreation rooms, enclosed porches suitable for
 year-round use, and lodger's rooms. Excluded are strip or pullman
 kitchens, bathrooms, open porches, balconies, halls or foyers,
 half-rooms, utility rooms, unfinished attics or basements, or other
 unfinished space used for storage. A partially divided room is a
 separate room only if there is a partition from floor to ceiling, but
 not if the partition consists solely of shelves or cabinets.

 Median Rooms--This measure divides the room distribution into two equal
 parts, one-half of the cases falling below the median number of rooms and
 one-half above the median. In computing median rooms, the whole number
 is used as the midpoint of the interval; thus, the category "3
 rooms" is treated as an interval ranging from 2.5 to 3.5 rooms.
 Median rooms is rounded to the nearest tenth. (For more information on
 medians, see the discussion under "Derived Measures.")

 Aggregate Rooms--To calculate aggregate rooms, an arbitrary value of "10"
 is assigned to rooms for units falling within the terminal category, "9
 or more." (For more information on aggregates and means, see the
 discussion under "Derived Measures.")

 Comparability--Data on rooms have been collected since 1940. In 1970 and
 1980, these data were shown only for year-round housing units. In 1990,
 these data are shown for all housing units.

 Tenure

 The data for tenure were obtained from questionnaire item H4, which
 was asked at all occupied housing units. All occupied housing units are
 classified as either owner occupied or renter occupied.

 Owner Occupied--A housing unit is owner occupied if the owner or co-owner
 lives in the unit even if it is mortgaged or not fully paid for. The owner
 or co-owner must live in the unit and usually is the person listed in
 column 1 of the questionnaire. The unit is "Owned by you or someone
 in this household with a mortgage or loan" if it is being purchased
 with a mortgage or some other debt arrangement such as a deed of trust,
 trust deed, contract to purchase, land contract, or purchase agreement.
 The unit is also considered owned with a mortgage if it is built on
 leased land and there is a mortgage on the unit.

 A housing unit is "Owned by you or someone in this household free
 and clear (without a mortgage)" if there is no mortgage or other
 similar debt on the house, apartment, or mobile home including units
 built on leased land if the unit is owned outright without a mortgage.
 Although owner-occupied housing units are divided between mortgaged and
 owned free and clear on the questionnaire, census data products
 containing 100-percent data show only total owner-occupied counts. More
 extensive mortgage information was collected on the long-form
 questionnaire and are shown in census products containing sample data.

 Renter Occupied--All occupied housing units which are not owner occupied,
 whether they are rented for cash rent or occupied without payment of cash
 rent, are classified as renter occupied. "No cash rent" units are
 separately identified in the rent tabulations. Such units are generally
 provided free by friends or relatives or in exchange for services such
 as a resident manager, caretaker, minister, or tenant farmer. Housing
 units on military bases also are classified in the "No cash rent"
 category.

 "Rented for cash rent" includes units in continuing care,
 sometimes called life care arrangements. These arrangements usually
 involve a contract between one or more individuals and a health
 services provider guaranteeing the individual shelter, usually a house
 or apartment, and services, such as meals or transportation to shopping
 or recreation.

 Comparability--Data on tenure have been collected since 1890. In 1970, the
 question on tenure also included a category for condominium and cooperative
 ownership. In 1980, condominium units and cooperatives were dropped
 from the tenure item, and since 1980, only condominium units are
 identified in a separate question.

 For 1990, the response categories were expanded to allow the respondent
 to report whether the unit was owned with a mortgage or free and clear
 (without a mortgage). The distinction between units owned with a
 mortgage and units owned free and clear was added in 1990 to improve
 the count of owner-occupied units. Research after the 1980 census
 indicated some respondents did not consider their units owned if they
 had a mortgage.

 Units in Structure

 The data on units in structure (also referred to as "type of
 structure") were obtained from questionnaire item H2, which was
 asked at all housing units. A structure is a separate building that
 either has open spaces on all sides or is separated from other
 structures by dividing walls that extend from ground to roof. In
 determining the number of units in a structure, all housing units, both
 occupied and vacant, are counted. Stores or office space are excluded.

 The statistics are presented for the number of housing units in
 structures of specified type and size, not for the number of
 residential buildings.

 1-Unit, Detached--This is a 1-unit structure detached from any other
 structure, that is, with open space on all four sides. Such structures are
 considered detached even if they have an adjoining shed or garage. A one-
 family house which contains a business is considered detached as long as
 the building has open space on all four sides. Mobile homes or trailers to
 which one or more permanent rooms have been added or built are also
 included.

 1-Unit, Attached--This is a 1-unit structure which has one or more walls
 extending from ground to roof separating it from adjoining structures. In
 row houses (sometimes called townhouses), double houses, or houses attached
 to nonresidential structures, each house is a separate, attached structure
 of the dividing or common wall goes from ground to roof.

 2 or More Units--These are units in structures containing 2 or more housing
 units, further categorized as units in structures with 2, 3 or 4, 5 to 9,
 10 to 19, 20 to 49, and 50 or more units.

 Mobile Home or Trailer--Both occupied and vacant mobile homes to which no
 permanent rooms have been added are counted in this category. Mobile homes
 or trailers used only for business purposes or for extra sleeping space and
 mobile homes or trailers for sale on a dealer's lot, at the factory, or in
 storage are not counted in the housing inventory.

 Other--This category is for any living quarters occupied as a housing unit
 that does not fit the previous categories. Examples that fit this
 category are houseboats, railroad cars, campers, and vans.

 Comparability--Data on units in structure have been collected since 1940
 and on mobile homes and trailers since 1950. In 1970 and 1980, these data
 were shown only for year-round housing units. In 1990, these data are shown
 for all housing units. In 1980, the data were collected on a sample basis.
 The category, "Boat, tent, van, etc." was replaced in 1990 by the
 category, "Other." In some areas, the proportion of units
 classified as "Other" is far larger than the number of units that
 were classified as "Boat, tent, van, etc." in 1980.

 Usual Home Elsewhere

 The data for usual home elsewhere were obtained from questionnaire
 item B, which was completed by census employees. A housing unit
 temporarily occupied at the time of enumeration entirely by persons
 with a usual residence elsewhere is classified as vacant. The occupants
 are classified as having a "Usual home elsewhere" and are counted
 at the address of their usual place of residence. Typical examples are
 people in a vacation home, persons renting living quarters temporarily
 for work, and migrant workers.

 Limitation of the Data--Evidence from previous censuses suggests that in
 some areas enumerators marked units as "vacant--usual home elsewhere" when
 they should have marked "vacant--regular."

 Comparability--Data for usual home elsewhere were tabulated for the first
 time in 1980.

 Vacancy Status

 The data on vacancy status were obtained from questionnaire item C1,
 which was completed by census enumerators. Vacancy status and other
 characteristics of vacant units were determined by enumerators
 obtaining information from landlords, owners, neighbors, rental agents,
 and others. Vacant units are subdivided according to their housing
 market classification as follows:

   For Rent--These are vacant units offered "for
   rent" and vacant units offered either "for rent or for sale."

   For Sale Only--These are vacant units being offered
   "for sale only," including units in cooperatives and condominium
   projects if the individual units are offered "for sale only."

   Rented or Sold, Not Occupied--If any money rent has
   been paid or agreed upon but the new renter has not moved in as of the
   date of enumeration, or if the unit has recently been sold but the new
   owner has not yet moved in, the vacant unit is classified as "rented
   or sold, not occupied."

   For Seasonal, Recreational, or Occasional Use--These
   are vacant units used or intended for use only in certain seasons or
   for weekend or other occasional use throughout the year. Seasonal units
   include those used for summer or winter sports or recreation, such as
   beach cottages and hunting cabins. Seasonal units may also include
   quarters for such workers as herders and loggers.

   For Migrant Workers--These include vacant units
   intended for occupancy by migratory workers employed in farm work
   during the crop season. (Work in a cannery, a freezer plant, or a feed
   processing plant is not farm work.)

   Other Vacant--If a vacant unit does not fall into any
   of the classifications specified above, it is classified as "other
   vacant." For example, this category includes units held for
   occupancy by a caretaker or janitor, and units held for personal
   reasons of the owner.

 Homeowner Vacancy Rate--This is the percentage relationship between the
 number of vacant units for sale and the total homeowner inventory. It is
 computed by dividing the number of vacant units for sale only by the sum of
 the owner-occupied units and the number of vacant units that are for sale
 only.

 Rental Vacancy Rate--This is the percentage relationship of the number of
 vacant units for rent to the total rental inventory. It is computed by
 dividing the number of vacant units for rent by the sum of the renter-
 occupied units and the number of vacant units for rent.

 Comparability--Data on vacancy status have been collected since 1940. For
 1990, the category, "seasonal/recreational/occasional use" combined vacant
 units classified in 1980 as "seasonal or migratory" and "held
 for occasional use." Also, in 1970 and 1980, housing characteristics
 were generally presented only for year-round units. In 1990, housing
 characteristics are shown for all housing units.

 Value

 The data on value (also referred to as "price asked" for
 vacant units) were obtained from questionnaire item H6, which was asked
 at occupied housing units that were owned, being bought, or vacant for
 sale at the time of enumeration. Value is the respondent's estimate of
 how much the property (house and lot, mobile home and lot, or
 condominium unit) would sell for if it were for sale. If the house or
 mobile home is owned or being bought, but the land on which it sits is
 not, the respondent was asked to estimate the combined value of the
 house or mobile home and the land. For vacant units, value is the price
 asked for the property.

 Value is tabulated separately for all owner-occupied and
 vacant-for-sale-only housing units, owner-occupied and vacant-for-sale
 mobile homes or trailers, and specified owner-occupied and specified
 vacant-for-sale-only housing units. Specified owner-occupied and
 specified vacant-for-sale-only housing units include only one-
 family houses on less than 10 acres without a business or medical office
 on the property. The data for "specified" units exclude mobile
 homes, houses with a business or medical office, houses on 10 or more
 acres, and housing units in multi-unit buildings.

 Median and Quartile Value--The median divides the value distribution into
 two equal parts.  Quartiles divide the value distribution into four equal
 parts. These measures are rounded to the nearest hundred dollars. (For more
 information on medians and quartiles, see the discussion under
 "Derived Measures.")

 Aggregate Value--To calculate aggregate value, the amount assigned for the
 category "Less than $10,000" is $9,000. The amount assigned to the
 category "$500,000 or more" is $600,000. Mean value is rounded to
 the nearest whole dollar. (For more information on aggregates and
 means, see the discussion under "Derived Measures.")

 Comparability--In 1980, value was asked only at owner-occupied or vacant-
 for-sale one-family houses on less than 10 acres with
 no business or medical office on the property and at all owner-occupied
 or vacant-for-sale condominium housing units. Mobile homes were
 excluded. Value data were presented for specified owner-occupied
 housing units, specified vacant-for-sale-only housing units, and
 owner-occupied condominium housing units.

 In 1990, the question was asked at all owner-occupied or
 vacant-for-sale-only housing units with no exclusions. Data presented
 for specified owner-occupied and specified vacant-for-sale-only housing
 units will include one-family condominium houses but not condominiums in
 multi-unit structures since condominium units are now identified only in
 long-form questionnaires.

 For 1990, quartiles have been added because the range of values and
 rents in the United States has increased in recent years. Upper and
 lower quartiles can be used to note large value and rent differences
 among various geographic areas.

 Derived Measures

 General Information

 Census data products include various derived measures such as
 medians, means, and percentages, as well as certain rates and ratios.
 Derived measures which round to less than 0.1 are not shown but
 indicated as zero. In printed reports, zero is indicated by showing a
 dash (-).

 Interpolation

 Interpolation is frequently used in calculating medians or quartiles
 based on interval data and in approximating standard errors from
 tables. Linear interpolation is used to estimate values of a function
 between two known values. "Pareto interpolation" is an
 alternative to linear interpolation. It is used by the Census Bureau in
 calculating median income within intervals wider than $2,500. In Pareto
 interpolation, the logarithm of the median is derived by interpolating
 between the logarithms of the upper and lower income limits of the
 median category.

 Mean

 This measure represents an arithmetic average of a set of values. It
 is derived by dividing the sum of a group of numerical items (or
 aggregate) by the total number of items. Aggregates are used in
 computing mean values. For example, mean family income is obtained by
 dividing the aggregate of all income reported by persons in families by
 the total number of families. (Additional information on means and
 aggregates is included in the separate explanations of many population
 and housing subjects.)

 Median

 This measure represents the middle value in a distribution. The
 median divides the total frequency into two equal parts: one-half of
 the cases fall below the median and one-half of the cases exceed the
 median. The median is computed on the basis of the distribution as
 tabulated, which is sometimes more detailed than the distribution shown
 in specific census publications and other data products.

 In reports, if the median falls within the upper interval of an
 open-ended distribution, the median is shown as the initial value of
 the interval followed by a plus sign (+), or if within the lower
 interval, the median is shown as the upper value of the category
 followed by a minus sign (-). For summary tape files, if the median
 falls within the upper or lower interval, it is set to a specified
 value. (Additional information on medians is included in the separate
 explanations of many population and housing subjects.)

 Percentages, Rates, and Ratios

 These measures are frequently presented in census
 products and are used to compare two numbers or two sets of
 measurements. These comparisons are made in two ways: (1) subtraction
 which provides an absolute measure of the difference between two items
 and (2) the quotient of two numbers which provides a relative measure
 of difference.

 Quartile

 This measure divides a distribution into four equal parts. The first
 quartile (or lower quartile) is the value that defines the upper limit
 of the lowest one-quarter of the cases. The second quartile is the
 median. The third quartile (or upper quartile) defines the lower limit
 of the upper one-quarter of the cases in the distribution. The
 difference between the upper and lower quartiles is called the
 interquartile range. This interquartile range is less affected by wide
 variations than is the mean. Quartiles are presented for certain
 financial characteristics such as housing value and rent.

 Confidentiality of the Data

 To maintain confidentiality required by law (Title 13, United States
 Code), the Bureau of the Census applies a confidentiality edit to
 assure published data do not disclose information about specific
 individuals, households, and housing units. The result is that a small
 amount of uncertainty is introduced into some of the census
 characteristics to prevent identification of specific individuals,
 households, or housing units. The edit is controlled so that the counts
 of total persons, totals by race and American Indian tribe, Hispanic
 origin, and age 18 years and over are not affected by the
 confidentiality edit and are published as collected. In addition, total
 counts for housing units by tenure are not affected by this edit.

 The confidentiality edit is conducted by selecting a sample of census
 households from the 100-percent data internal census files and
 interchanging its data with other households that have identical
 characteristics on a set of selected key variables but are in different
 geographic locations within the same State. To provide more protection
 for "small areas," a higher sampling rate was used for these
 areas. The net result of this procedure is that the data user's ability
 to obtain census data, particularly for small areas and subpopulation
 groups, has been significantly enhanced.

 Editing of Unacceptable Data

 The objective of the processing operation is to produce a set of
 data that describes the population as accurately and clearly as
 possible. To meet this objective, questionnaires were edited during
 field data collection operations for consistency, completeness, and
 acceptability. Questionnaires were also reviewed by census clerks for
 omissions, certain inconsistencies, and population coverage. For
 example, write-in entries such as "Don't know" or "NA" were
 considered unacceptable. For some district offices, the initial edit
 was automated; however, for the majority of the district offices, it
 was performed by clerks. As a result of this operation, a telephone or
 personal visit follow-up was made to obtain missing information.
 Potential coverage errors were included in the follow-up, as well as a
 sample of questionnaires with omissions or inconsistencies.

 Subsequent to field operations, remaining incomplete or inconsistent
 information on the questionnaires was assigned using imputation
 procedures during the final automated edit of the collected data.
 Allocations, or computer assignments of acceptable codes in place of
 unacceptable entries or blanks, are needed most often when an entry for
 a given item is lacking or when the information reported for a person
 or housing unit on that item is inconsistent with other information for
 that same person or housing unit. As in previous censuses, the general
 procedure for changing unacceptable entries was to assign an entry for
 a person or housing unit that was consistent with entries for persons
 or housing units with similar characteristics. The assignment of
 acceptable codes in place of blanks or unacceptable entries enhances
 the usefulness of the data.

 Another way in which corrections were made during the computer editing
 process was through substitution; that is, the assignment of a full set
 of characteristics for a person or housing unit. When there was an
 indication that a housing unit was occupied, but the questionnaire
 contained no information for the people within the household, or the
 occupants were not listed on the questionnaire, a previously accepted
 household was selected as a substitute, and the full set of
 characteristics for the substitute was duplicated. The assignment of
 the full set of housing characteristics occurred when there was no
 housing information available. If the housing unit was determined to be
 occupied, the housing characteristics were assigned from a previously
 processed occupied unit. If the housing unit was vacant, the housing
 characteristics were assigned from a previously processed vacant unit.

 Sources of Error

 In any large-scale statistical operation, such as the 1990 decennial
 census, human- and machine-related errors occur. These errors are
 commonly referred to as nonsampling errors. Such errors include not
 enumerating every household or every person in the population, not
 obtaining all required information from the respondents, obtaining
 incorrect or inconsistent information, and recording information
 incorrectly. In addition, errors can occur during the field review of
 the enumerators' work, during clerical handling of the census
 questionnaires, or during the electronic processing of the
 questionnaires.

 To reduce various types of nonsampling errors, a number of techniques
 were implemented during the planning, development of the mailing
 address list, data collection, and data processing activities. Quality
 assurance methods were used throughout the data collection and
 processing phases of the census to improve the quality of the data. A
 reinterview program was designed to minimize the errors in the data
 collection phase for enumerator-filled questionnaires.

 Several coverage improvement programs were implemented during the
 development of the census address list and census enumeration and
 processing to minimize undercoverage of the population and housing
 units. These programs were developed based on experience from the 1980
 decennial census and results from the 1990 decennial census testing
 cycle. In developing and updating the census address list, the Census
 Bureau used a variety of specialized procedures in different parts of
 the country.

   - For larger urban areas, the Census Bureau purchased and coded
     address lists, had the United States Postal Service (USPS) review and
     update this list, and conducted a dependent canvass and update
     operation. Prior to mailout, local officials were given the opportunity
     to examine block counts of address listings (local review) and identify
     possible errors, and the USPS conducted a final review.

   - For small cities and suburban and selected rural parts of the
     country, the Census Bureau created the address list through a listing
     operation that occurred in 1988 and 1989. For the addresses listed in
     1988, the USPS reviewed and updated this list, and the Census Bureau
     reconciled USPS corrections through a field check; prior to mailout,
     the USPS conducted a final review of these addresses, and local
     officials participated in reviewing block counts of address listings.

 Coverage improvement programs continued during and after mailout.
 The Census Bureau (rather than the USPS) delivered census
 questionnaires in the rural and seasonal housing areas listed in 1989
 and in inner-city public housing developments. Computer and clerical
 edits and telephone and personal visit followups contributed to
 improved coverage.

 If the 1990 census is not subject to count adjustment, the population
 counts shown in 100-percent data products will be tabulated from the
 entries for persons on all questionnaires. These counts will not be
 subject to sampling error. If count adjustment is done, a discussion of
 the count adjustment methodology and the appropriate methods for
 calculating sampling errors of adjusted counts can be found in appendix
 H. (Housing unit counts will not be subject to count adjustment.)

 Enumeration and Residence Rules

 Description

 In accordance with census practice dating back to the first United
 States census in 1790, each person was to be enumerated as an
 inhabitant of his or her "usual residence" in the 1990 census.
 Usual residence is the place where the person lives and sleeps most of
 the time or considers to be his or her usual residence. This place is
 not necessarily the same as the person's legal residence or voting
 residence. In the vast majority of cases, however, the use of these
 different bases of classification would produce substantially the same
 statistics, although there might be appreciable differences for a few
 areas.

 The implementation of this practice has resulted in the establishment
 of rules for certain categories of persons whose usual place of
 residence is not immediately apparent. Furthermore, this practice means
 that persons were not always counted as residents of the place where
 they happened to be staying on Census Day (April 1, 1990).

 Enumeration Rules

 Each person whose usual residence was in the United States was to be
 included in the census, without regard to the person's legal status or
 citizenship. In a departure from earlier censuses, foreign diplomatic
 personnel participated voluntarily in the census, regardless of their
 residence on or off the premises of an embassy. As in previous
 censuses, persons in the United States specifically excluded from the
 census were foreign travelers who had not established a residence.

 Americans with a usual residence outside the United States were not
 enumerated in the 1990 census. United States military and Federal
 civilian employees, and their dependents overseas, are included in the
 population counts for States for purposes of Congressional
 apportionment, but are excluded from all other tabulations for States
 and their subdivisions. The counts of United States military and
 Federal civilian employees, and their dependents, were obtained from
 administrative records maintained by Federal departments and agencies.
 Other Americans living overseas, such as employees of international
 agencies and private businesses and students, were not enumerated, nor
 were their counts obtained from administrative sources. On the other
 hand, Americans temporarily overseas were to be enumerated at their
 usual residence in the United States.

 Residence Rules

 Each person included in the census was to be counted at his or her
 usual residence--the place where he or she lives and sleeps most of the
 time or the place where the person considers to be his or her usual
 home. If a person had no usual residence, the person was to be counted
 where he or she was staying on April 1, 1990.

 Persons temporarily away from their usual residence, whether in the
 United States or overseas, on a vacation or on a business trip, were
 counted at their usual residence. Persons who occupied more than one
 residence during the year were counted at the one they considered to be
 their usual residence. Persons who moved on or near Census Day were
 counted at the place they considered to be their usual residence.

 Persons in the Armed Forces--Members of the Armed Forces were counted as
 residents of the area in which the installation was located, either on the
 installation or in the surrounding community. Family members of Armed
 Forces personnel were counted where they were living on Census Day (for
 example, with the Armed Forces person or at another location).

 Each Navy ship not deployed to the 6th or 7th Fleet was attributed to
 the municipality that the Department of the Navy designated as its
 homeport. If the homeport included more than one municipality, ships
 berthed there on Census Day were assigned by the Bureau of the Census
 to the municipality in which the land immediately adjacent to the dock
 or pier was actually located. Ships attributed to the homeport, but not
 physically present and not deployed to the 6th or 7th Fleet, were
 assigned to the municipality named on the Department of the Navy's
 homeport list. These rules also apply to Coast Guard vessels.

 Personnel assigned to each Navy and Coast Guard ship were given the
 opportunity to report a residence off the ship. Those who did report an
 off-ship residence in the communities surrounding the homeport were
 counted there; those who did not were counted as residents of the ship.
 Personnel on Navy ships deployed to the 6th or 7th Fleet on Census Day
 were considered to be part of the overseas population.

 Persons on Maritime Ships--Persons aboard maritime ships who reported an
 off-ship residence were counted at that residence. Those who did not were
 counted as residents of the ship, and were attributed as follows:

 1.  The port where the ship was docked on Census Day, if that port was
     in the United States or its possessions.

 2.  The port of departure if the ship was at sea, provided the port was
     in the United States or its possessions.

 3.  The port of destination in the United States or its possessions, if
     the port of departure of a ship at sea was a foreign port.

 4.  The overseas population if the ship was docked at a foreign port or
     at sea between foreign ports. (These persons were not included in the
     overseas population for apportionment purposes.)

 Persons Away at School--College students were counted as residents of the
 area in which they were living while attending college, as they have been
 since the 1950 census. Children in boarding schools below the college level
 were counted at their parental home.

 Persons in Institutions--Persons under formally authorized, supervised care
 or custody, such as in Federal or State prisons; local jails; Federal
 detention centers; juvenile institutions; nursing, convalescent, and rest
 homes for the aged and dependent; or homes, schools, hospitals, or wards
 for the physically handicapped, mentally retarded, or mentally ill, were
 counted at these places.

 Persons Away From Their Usual Residence on Census Day--Migrant agricultural
 workers who did not report a usual residence elsewhere were counted as
 residents of the place where they were on Census Day. Persons in worker
 camps who did not report a usual residence elsewhere were counted as
 residents of the camp where they were on Census Day.

 In some parts of the country, natural disasters displaced significant
 numbers of households from their usual place of residence. If these
 persons reported a destroyed or damaged residence as their usual
 residence, they were counted at that location.

 Persons away from their usual residence were counted by means of
 interviews with other members of their families, resident managers, or
 neighbors.

 Data Collection Procedures

 Description

 The 1990 census was conducted primarily through self-enumeration.
 The questionnaire packet included general information about the 1990
 census and an instruction guide explaining how to complete the
 questionnaire. Spanish-language questionnaires and instruction guides
 were available on request. Instruction guides also were available in 32
 other languages.

 Enumeration of Housing Units

 Each housing unit in the country received one of two versions of the
 census questionnaire:

 1.  A short-form questionnaire that contained a limited number of basic
     population and housing questions; these questions were asked of all
     persons and housing units and are often referred to as 100-
     percent questions.

 2.  A long-form questionnaire that contained the 100-percent items and a
     number of additional questions; a sampling procedure was used to
     determine those housing units that were to receive the long-form
     questionnaire.

 Three sampling rates were employed. For slightly more than one-half
 of the country, one in every six housing units (about 17 percent)
 received the long-form or sample questionnaire. In functioning local
 governmental units (counties and incorporated places, and in some parts
 of the country, towns and townships) estimated to have fewer than 2,500
 inhabitants, every other housing unit (50 percent) received the sample
 questionnaire in order to enhance the reliability of the sample data
 for these small areas. For census tracts and block numbering areas
 having more than 2,000 housing units in the Census Bureau's address
 files, one in every eight housing units (about 13 percent) received a
 sample questionnaire, providing reliable statistics for these areas
 while permitting the Census Bureau to stay within a limit of 17.7
 million sample questionnaires, or a one-in-six sample, nationwide.

 The mail-out/mail-back procedure was used mainly in cities, suburban
 areas, towns, and rural areas where mailing addresses consisted of a
 house number and street name. In these areas, the Census Bureau
 developed mailing lists that included about 88.4 million
 addresses. The questionnaires were delivered through the mail and
 respondents were to return them by mail. Census questionnaires were
 delivered 1 week before Census Day (April 1, 1990)

 The update/leave/mail-back method was used mainly in densely populated
 rural areas where it was difficult to develop mailing lists because
 mailing addresses did not use house number and street name.
 The Census Bureau compiled lists of housing units in advance of the
 census. Enumerators delivered the questionnaires, asked respondents to
 return them by mail, and added housing units not on the mailing lists.
 This method was used mainly in the South and Midwest, and also included
 some high-rise, low-income urban areas. A variation of this method was used
 in urban areas having large numbers of boarded-up buildings. About 11
 million housing units were enumerated using this method.

 The list/enumerate method (formerly called conventional or door-to-door
 enumeration) was used mainly in very remote and sparsely-settled areas.
 The United States Postal Service delivered unaddressed short-form
 questionnaires before Census Day. Starting a week before Census Day,
 enumerators canvassed these areas, checked that all housing units
 received a questionnaire, created a list of all housing units,
 completed long-form questionnaires, and picked up the completed
 short-form questionnaires. This method was used mainly in the West and
 Northeast to enumerate an estimated 6.5 million housing units.

 Followup

 Nonresponse Followup--In areas where respondents were to mail back their
 questionnaires, an enumerator visited each address from which a
 questionnaire was not received.

 Coverage and Edit-Failure Followup--In the mail-back areas, some households
 returned a questionnaire that did not meet specific quality standards
 because of incomplete or inconsistent information, or the respondent had
 indicated difficulty in deciding who was to be listed on the questionnaire.
 These households were contacted by telephone or by personal visit to obtain
 the missing information or to clarify who was to be enumerated in the
 household. In areas where an enumerator picked up the questionnaires, the
 enumerator checked the respondent-filled questionnaire for completeness and
 consistency.

 Special Enumeration Procedures

 Special procedures and questionnaires were used for the enumeration
 of persons in group quarters, such as college dormitories, nursing
 homes, prisons, military barracks, and ships. The questionnaires
 (Individual Census Reports, Military Census Reports, and Shipboard
 Census Reports) included the 100-percent population questions but did
 not include any housing questions. In all group quarters, all persons
 were asked the basic population questions; in most group quarters,
 additional questions were asked of a sample (one-in-six) of persons.

 Shelter and Street Night (S-Night)

 The Census Bureau collected data for various components of the
 homeless population at different stages in the 1990 census. "Shelter
 and Street Night" (S-Night) was a special census operation to count
 the population in four types of locations where homeless people are
 found. On the evening of March 20, 1990, and during the early morning
 hours of March 21, 1990, enumerators counted persons in pre-identified
 locations:

 1.  Emergency shelters for the homeless population (public and private;
     permanent and temporary).

 2.  Shelters with temporary lodging for runaway youths.

 3.  Shelters for abused women and their children.

 4.  Open locations in streets or other places not intended for habitation.


 Emergency shelters include all hotels and motels costing $12 or less
 (excluding taxes) per night regardless of whether persons living there
 considered themselves to be homeless, hotels and motels (regardless of
 cost) used entirely to shelter homeless persons, and pre-identified
 rooms in hotels and motels used for homeless persons and families.
 Enumeration in shelters usually occurred from 6 p.m. to midnight;
 street enumeration, from 2 a.m. to 4 a.m.; abandoned and boarded-up
 buildings from 4 a.m. to 8 a.m.; and shelters for abused women, from 6
 p.m. on March 20 to noon on March 21.

 Other components, which some consider as part of the homeless
 population, were enumerated as part of regular census operations. These
 include persons doubled up with other families, as well as persons with
 no other usual home living in transient sites, such as commercial
 campgrounds, maternity homes for unwed mothers, and drug/alcohol abuse
 detoxification centers. In institutions, such as local jails and mental
 hospitals, the Census Bureau does not know who has a usual home
 elsewhere; therefore, even though some are literally homeless, these
 persons cannot be identified separately as a component of the homeless
 population.

 There is no generally agreed-upon definition of "the homeless,"
 and there are limitations in the census count that prevent obtaining a
 total count of the homeless population under any definition. As such,
 the Census Bureau does not have a definition and will not provide a
 total count of "the homeless." Rather, the Census Bureau will
 provide counts and characteristics of persons found at the time of the
 census in selected types of living arrangements. These
 selected components can be used as building blocks to construct a count
 of homeless persons appropriate to particular purposes as long as the
 data limitations are taken into account.

 In preparation for "Shelter-and-Street-Night" enumeration, the
 regional census centers (RCC's) mailed a certified letter (Form D-33
 (L)) to the highest elected official of each active functioning
 government of the United States (more than 39,000) requesting them to
 identify:

 1.  All shelters with sleeping facilities (permanent and temporary,
     such as church basements, armories, public buildings, and so forth,
     that could be open on March 20).

 2.  Hotels and motels used to house homeless persons and families.

 3.  A list of outdoor locations where homeless persons tend to be at
     night.

 4.  Places such as bus or train stations, subway stations, airports,
     hospital emergency rooms, and so forth, where homeless persons seek
     shelter at night.

 5.  The specific addresses of abandoned or boarded-up buildings where
     homeless persons were thought to stay at night.

 The letter from the RCC's to the governmental units emphasized the
 importance of listing night-time congregating sites. The list of
 shelters was expanded using information from administrative records and
 informed local sources. The street sites were limited to the list
 provided by the jurisdictions. All governmental units were eligible for
 "Shelter and Street Night." For cities with 50,000 or more
 persons, the Census Bureau took additional steps to update the list of
 shelter and street locations if the local jurisdiction did not respond
 to the certified letter. Smaller cities and rural areas participated if
 the local jurisdiction provided the Census Bureau a list of shelters or
 open public places to visit or if shelters were identified through our
 inventory development, local knowledge update, or during the Special
 Place Prelist operation.

 The Census Bureau encouraged persons familiar with homeless persons and
 the homeless themselves to apply as enumerators. This recruiting effort
 was particularly successful in larger cities.

 For shelters, both long- and short-form Individual Census Reports
 (ICR's) were distributed. For street enumeration, only short-form
 ICR's were used. Persons in shelters and at street locations were
 asked the basic population questions. Additional questions about social
 and economic characteristics were asked of a sample of persons in
 shelters only.

 Enumerators were instructed not to ask who was homeless;
 rather, they were told to count all persons (including children)
 staying overnight at the shelters, and everyone they saw on the street
 except the police, other persons in uniform, and persons engaged in
 employment or obvious money-making activities other than begging and
 panhandling.

 At both shelter and street sites, persons found sleeping were not
 awakened to answer questions. Rather, the enumerator answered the sex
 and race questions by observation and estimated the person's age to the
 best of his or her ability. In shelters, administrative records and
 information from the shelter operator were used, when available, for
 persons who were already asleep.

 Less than 1 percent of shelters refused to participate in the census
 count at first. By the end of the census period, most of those
 eventually cooperated and the number of refusals had been reduced to a
 few. For the final refusals, head counts and population characteristics
 were obtained by enumerators standing outside such shelters and
 counting people as they left in the morning.

 The "street" count was restricted to persons who were visible
 when the enumerator came to the open, public locations that had been
 identified by local jurisdictions. Homeless persons who were well
 hidden, moving about, or in locations other than those identified by
 the local governments were likely missed. The number missed will never
 be known and there is no basis to make an estimate of the number missed
 from census data. The count of persons in open, public places was
 affected by many factors, including the extra efforts made to encourage
 people to go to shelters for "Shelter and Street Night," the
 weather (which was unusually cold in many parts of the country), the
 presence of the media, and distrust of the census. Expectations of the
 number of homeless persons on the street cannot be based on the number
 seen during the day because the night-time situation is normally very
 different as more homeless persons are in shelters or very well hidden.


 For both "Shelter-and-Street-Night" locations, the Census Bureau
 assumed that the usual home of those enumerated was in the block where
 they were found (shelter or street).

 The "Shelter-and-Street-Night" operation replaced and expanded
 the 1980 Mission Night (M-Night) and Casual Count operations. These two
 operations were aimed at counting the population who reported having no
 usual residence. M-Night was conducted a week after Census Day, in
 April 1980. Enumerators visited hotels, motels, and similar places
 costing $4 or less each night; missions, flophouses, local jails and
 similar places at which the average length of stay was 30 days or less;
 and nonshelter locations, such as bus depots, train stations, and all
 night movie theaters. Questions were asked of everyone, regardless of
 age. Enumerators conducted M-Night up to midnight on April 8, 1980, and
 returned the next morning to collect any forms completed after
 midnight.

 The Casual Count operation was conducted in May 1980 at additional
 nonshelter locations, such as street corners, pool halls, welfare and
 employment offices. This operation lasted for approximately 2 weeks.
 Casual Count was conducted during the day only in selected large
 central cities. Only persons who appeared to be at least 15 years of
 age were asked if they had been previously enumerated. Casual Count was
 actually a coverage-improvement operation. It was not specifically an
 operation to count homeless persons living in the streets. Persons were
 excluded if they said they had a usual home outside the city because it
 was not cost effective to check through individual questionnaires in
 another city to try to find the person.

 Processing Procedures

 Respondents returned many census questionnaires by mail to 1 of over
 344 census district offices or to one of six processing offices. In
 these offices, the questionnaires were "checked in" and edited
 for completeness and consistency of the responses. After this initial
 processing had been performed, all questionnaires were sent to the
 processing offices.

 In the processing offices, the household questionnaires were
 microfilmed and processed by the Film Optical Sensing Device for Input
 to Computers (FOSDIC). For most items on the questionnaire, the
 information supplied by the respondent was indicated by filling circles
 in predesignated positions. FOSDIC electronically "read" these
 filled circles from the microfilm copy of the questionnaire and
 transferred the information to computer tape. The computer tape did not
 include individual names, addresses, or handwritten responses.

 The data processing was performed in several stages. All questionnaires
 were microfilmed, "read" by FOSDIC, and transferred to computer
 disk. Selected written entries in the race question on both the short
 and long forms were keyed from the microfilm and coded using the data
 base developed from the 1980 census and subsequent content and
 operational tests. Keying of other written entries on the long forms
 occurred in the seven processing offices.

 The information (for example, income dollar amounts or homeowner
 shelter costs) on these keyed files was merged with the FOSDIC data or
 processed further through one of three automated coding programs. The
 codes for industry, occupation, place-of-birth, migration,
 place-of-work, ancestry, language, relationship, race, and Hispanic
 origin were merged with the FOSDIC data for editing, weighting, and
 tabulating operations at Census Bureau headquarters. All responses to
 the questions on Individual Census Reports (ICR's), Military Census
 Reports (MCR's), and Shipboard Census Reports (SCR's) were keyed, not
 processed by microfilm or FOSDIC.

 The 1990 census data products, being released during 1991-93, are
 available in a variety of new and traditional media. The Census Bureau
 has increased the product options available to data users in an effort
 to meet a variety of requirements and maximize the usefulness of the
 data. For example, laser discs, called CD-ROM (compact disc--read-only
 memory), are a new data delivery medium.

 The Census Bureau also has expanded services and sources of assistance
 available to data users. For example, the State Data Center Program has
 been expanded to include over 1,400 organizations to provide data and
 services to the public.

 This appendix provides a detailed introduction to the 1990 census data
 products and related materials, such as maps and reference
 publications. It concludes by describing sources of assistance and
 other Census Bureau data available to the public.


 Data Products

 Description

 Printed reports and computer tape files traditionally are the most
 widely used products. The Census Bureau also offers data on microfiche,
 on CD-ROM laser discs, and through its online service,
 CENDATA(TM). These various products are described below. For
 information about prices and how to order, write or call Customer
 Services. (See the "Sources of Assistance" section for the
 address and phone number.)

 The data products present statistics about the subjects covered in the
 1990 census questionnaires. These subjects are listed in figure 3, page
 F-8. As the figure shows, there are 100-percent subjects (those
 covered in questions asked of everyone or about every housing unit) and
 sample subjects (those covered in questions asked at about one out of
 every six housing units). Generally, a data product presents either
 100-percent data prepared by tabulating the responses to the 100-
 percent questions from all questionnaires, or sample data prepared by
 tabulating only the responses to the 100-percent and sample questions
 from the "long-form" questionnaires. Two report series, 1990 CPH-3 and
 1990 CPH-4 (see figure 4, page F-9), present both 100-percent and sample
 data.

 Printed Reports

 Printed reports are the most convenient and readily available source
 of data for most census users. The Census Bureau releases the reports
 in several series (see figure 4) that are grouped under three broad
 titles: 1990 Census of Population and Housing (1990 CPH),
 1990 Census of Population (1990 CP), and 1990 Census
 of Housing (1990 CH). There also are reports, not reflected in
 figure 4, for the outlying areas of the Pacific. The reports are sold
 by the Superintendent of Documents, U.S. Government Printing Office.
 (See the "Sources of Assistance" section for the address and
 phone number.)

 In several series, there are separate reports for each State. The
 geographic coverage of the State reports is listed in figure 4. The
 United States summaries for these report series contain, for the most
 part, data for the United States, regions, divisions, States,
 metropolitan areas (MA's), urbanized areas (UA's), counties, American
 Indian and Alaska Native areas, places with 10,000 or more persons, and
 other large substate areas (for example, county subdivisions, such as
 towns and townships, with 10,000 or more persons in selected States).

 Report series that present data for small areas, such as census tracts,
 contain limited subject-matter detail (for example, counts of people by
 age ranges--under 5 years, 5 to 9 years, etc.--rather than by single
 years). Report series that include greater amounts of subject-matter
 detail include less geographic detail.
 
 Computer Tape Files

 The Census Bureau provides more data on tape and other
 machine-readable products than in printed reports. These products are
 sold by the Census Bureau's Customer Services. There are several
 general types of data files released on computer tape (available on
 both reels and cartridges). They are introduced below, and more
 information is presented in figures 5 and 6, pages F-12 through F-14.


 Public Law 94-171 Data--This data file presents the counts designed and
 formatted for use in legislative re-districting. These counts also are
 available on CD-ROM and paper listings. Excerpts are available on
 CENDATA(TM). The counts, for areas as small as blocks, census tracts, and
 voting districts, include totals for population, race groups, persons of
 Hispanic origin, population 18 years and over, and housing units. (See
 figure 6.)

 Summary Tape Files (STF's)-- These computer tape files provide statistics
 with greater subject-matter detail than printed reports. They also present
 statistics for some types of areas, such as block groups and blocks, that
 are not included in the reports. (See figure 5.)

   Here are some important features of STF's:

   -  Each STF presents a particular set of data tables for specific types
      of geographic areas.

   -  Each STF has three or more file types (indicated by a letter suffix
      attached to the STF number) that differ in the geographic levels
      reported, but contain the same data detail.

   -  STF's 1 and 2 contain 100-percent data, and STF's 3 and 4 offer
      sample data.

   -  STF's 1 and 3 report on smaller areas and offer less data detail
      than STF's 2 and 4.

   -  STF's 1 through 4 offer greater data detail than the 1980 STF's 1
      through 4.

 Subject Summary Tape Files (SSTF's)--These files are the source of the
 subject reports and provide greater subject-matter detail than the STF's.
 They present data for the United States, regions, and divisions, and, in
 some cases, also for States, counties, and large cities. (See figure 6.)

 Public Use Microdata Sample (PUMS) Files--These computer tape files (see
 figure 6) contain data from samples of long-form housing-unit records
 ("microdata") for large geographic areas. Each sample housing-unit record
 includes essentially all the 1990 census data collected about each person
 in a sample household and the characteristics of the housing unit.
 Information that could be used to identify an individual or a housing unit
 is not included in the file.

 Microdata files enable users to prepare customized tabulations and
 cross-tabulations of most items on the census questionnaire. There are
 two PUMS files:

   -  A file presenting a 5-percent sample of housing units in which each
      household record includes codes to let the user know in what area,
      such as a group of counties, a single county, or a place, the
      household is located. Each area identified must have a population of
      at least 100,000 and boundaries that do not cross State lines.

   -  A file presenting a 1-percent sample of housing units. Its household
      records include codes associating them with MA's and other large
      areas, the boundaries of which may cross State lines. (For the 1980
      census, there were two files with 1-percent samples. The 1-percent
      sample showing data for selected urbanized areas and other large areas
      will not be produced for the 1990 census.)

 Other Special Computer Tape Files--Other files include the Census/Equal
 Employment Opportunity (EEO) Special File and the County-to-County
 Migration File. (See figure 6.) The Census Bureau may prepare additional
 special files.

 Microfiche

 Block statistics are available on microfiche as they were for the
 1980 census. The microfiche present, in table format, a subset of the
 tabulations for census blocks found in STF 1B (see figure 5). In the
 1990 census, for the first time, the entire land area of the Nation and
 its possessions was block-numbered. This increased the number of blocks
 for which the Census Bureau provides data from 2.5 million in 1980 to 7
 million for 1990. The cost and storage of block data of this magnitude
 would be prohibitive if the data were published in printed reports.

 STF's 1A and 3A are available on microfiche, as well. As noted in
 figure 5, they provide data for a variety of geographic areas. Also,
 all printed reports are offered on microfiche from Customer Services
 soon after they are published.

 Compact Disc--Read-Only Memory (CD-ROM)

 For the 1990 census, the Public Law (P.L.) 94-171 file; an extract
 of STF 1B that presents selected statistics for blocks; and STF's 1A,
 1C, 3A, 3B, and 3C are also available on CD-ROM. (One 4 3/4-inch
 CD-ROM, a type of optical or laser disc, can hold the contents of
 approximately 1,600 flexible diskettes, or three or four high-density
 computer tapes.)

 Online Information Systems

 The Census Bureau began CENDATA(TM), its online information service, in
 1984. CENDATA(TM) is accessible through two information vendors, CompuServe
 and DIALOG. A number of Census Bureau reports, in whole or in part, are
 offered online. For the 1990 census, CENDATA(TM) provides up-to-date
 information about the availability of data products and carries selections
 of State, county, MA, and place data from the P.L. 94-171 tape file and
 STF's 1 and 3.

 Custom Data Products
 
 These products are for users who require unique tabulations that are
 not included in standard products; for example, information for locally
 defined geographic areas. Users also can order special microdata files.

 The cost of preparing custom products must be paid by the users who
 request them. Any data that the Census Bureau provides in these
 products are subject to the same standards applied to other data to
 ensure that confidential individual information is not revealed.

 User-Defined Areas Program (UDAP) Tabulations-- UDAP can
 provide a set of predefined data tables for locally defined areas that
 do not correspond to standard 1990 census geographic areas. Users
 identify the geographic areas of interest to them by delineating
 boundaries around groupings of census blocks on 1990 census County
 Block Maps or by electronically submitting the geographic components of
 their area of interest. (A contact for more information is given in the
 "Sources of Assistance" section.)

 Special Tabulations--The Census Bureau can prepare special data tabulations
 for any specific geographic or subject-matter area. Users should rely on
 standard reports, tapes, microfiche, or user-defined area tabulations
 whenever possible, since special tabulations tend to be substantially more
 expensive and take time to arrange and produce. (Contacts for more
 information are given in the "Sources of Assistance" section.)


 Geographic Products

 Maps
 
 Census Bureau maps are necessary for virtually all uses of
 small-area 1990 census data. They are needed to locate the specific
 geographic areas for which the census provides data and to study the
 spatial relationship of the data for analytic purposes. The Census
 Bureau prepares a variety of 1990 census maps. Among the most useful
 are these four series:

 County Block Maps--These maps show census blocks and
 their numbers; boundaries for statistical and governmental entities,
 such as census tracts and places; and physical features. The P.L.
 94-171 version of these maps also shows voting district boundaries in
 those States that furnished them. The maps are prepared on
 electrostatic plotters by county (or equivalent entity) with one or
 more map sheets each, depending on the size and shape of the area and
 the density of the block pattern. An average county requires 20 map
 sheets. The maps may be purchased from Customer Services.

 County Subdivision Outline Maps--Maps in this State-
 based series present the boundaries of the counties, county
 subdivisions, places, American Indian and Alaska Native areas
 (including off-reservation trust lands), tribal designated statistical
 areas, and tribal jurisdiction statistical areas. Electrostatic-plotter
 copies are available for purchase from Customer Services. Also, they
 appear on multiple page-size sheets in the State reports of these
 series: 1990 CPH-1, 1990 CPH-2, 1990 CPH-5, 1990 CP-1, 1990 CP-2, 1990
 CH-1, and 1990 CH-2.

 Census Tract/Block Numbering Area (BNA) Outline Maps--Maps in this county-
 based series depict census tract or BNA boundaries and numbers, and the
 features underlying the boundaries.  They also show governmental units in
 relation to the census tracts/BNA's. Customer Services sells electrostatic-
 plotter copies, and the Superintendent of Documents sells printed copies.

 Voting District Outline Maps--Maps in this county-based series depict
 voting district boundaries (for those counties for which States furnished
 boundary information) and the features underlying the boundaries. They also
 show governmental unit boundaries in relation to the voting districts. They
 are prepared on electrostatic plotters and sold by Customer Services.

 Geographic Publications

 The Geographic Identification Code Scheme report in the
 1990 CPH-R series shows the 1990 census geographic area codes and
 Federal information processing standards (FIPS) codes, as appropriate,
 for States, metropolitan areas, counties, county subdivisions, places,
 American Indian and Alaska Native areas, and other entities, along with
 some descriptive information about the codes. The code scheme also is
 offered on computer tape.

 Machine-Readable Geographic Files

 All 1990 census summary tape files include 1990 census geographic
 area codes, FIPS codes, certain area names, land and inland water area
 in square kilometers, geographic coordinates for an internal point for
 each entity, and other geographic information.

 The Census Bureau developed an automated geographic data base, known as
 the TIGER (Topologically Integrated Geographic Encoding and
 Referencing) System, to produce the geographic products for the 1990
 census. TIGER provides coordinate-based digital map information for the
 entire United States, Puerto Rico, the U.S. Virgin Islands, and the
 Pacific territories over which the United States has jurisdiction.

 The TIGER System has significantly improved the utility of 1990 census
 maps and geographic reference products. Extract files generated from
 the TIGER System permit users, with appropriate software, to perform
 such tasks as linking the statistical data in the P.L. 94-171 file or
 the STF's and displaying selected characteristics on maps or a video
 display screen at different scales and with whatever boundaries they
 select for any geographic area of the country. For example, a map for a
 particular county could show the distribution of the voting age
 population by city block.

 The first extract of selected geographic and cartographic information
 intended for computer applications, such as plotting maps and building
 geographic information systems, is called the TIGER/Line(TM)
 files. TIGER/Line(TM) files contain attributes for the
 segments of each boundary and feature (for example, roads, railroads,
 and rivers), including 1990 census geographic codes for adjacent areas,
 latitude/longitude coordinates of segment end points and the curvature
 of segments, the name and type of the feature, and the relevant census
 feature class code identifying the feature segment by category.
 TIGER/Line(TM) files also furnish address ranges and
 associated ZIP Codes for each side of street segments in major urban
 areas; provide the names of landmarks, such as lakes and golf courses;
 and include other information.

 TIGER/Line(TM) files and other TIGER System extracts, such as
 TIGER/Boundary(TM) and TIGER/DataBase(TM), are released on computer tape
 and, in some cases, CD-ROM. For information on TIGER extract files, contact
 Customer Services.

 Other Sources of Products and Services

 State Data Centers--The Census Bureau furnishes data
 products, training in data access and use, technical assistance, and
 consultation to all States, the District of Columbia, Guam, Puerto
 Rico, and the U.S. Virgin Islands. State Data Centers, in turn, offer
 publications for reference, printouts from computer tape, specially
 prepared reports, maps, and other products and assistance to data
 users. For a list of the State Data Centers, see the Census
 Catalog and Guide or contact Customer Services. The list also
 notes organizations in States participating in the Census Bureau's

 Depository Libraries--There are 1,400 libraries that
 receive (from the Government Printing Office) Federal publications that
 they think their patrons will need. Often some of these publications
 are Census Bureau reports. The Census Bureau provides free reports to
 an additional 120 census depository libraries. Also, many libraries
 purchase census reports and maps for their areas. The Census
 Catalog and Guide includes a list of all depository libraries.


 Other Census Bureau Resources

 General Information

 The Census Bureau has more to offer than just the results of the
 census of population and housing. Through other censuses, surveys, and
 estimates programs, it compiles and issues (in reports, computer tape,
 and other media) data on subjects as diverse as appliance sales,
 neighborhood conditions, and exports to other countries. Here are
 examples of the information published about--

   -  People:  Age, race, sex, income, poverty, child care,
      child support, fertility, noncash benefits, education, commuting
      habits, pension coverage, unemployment, ancestry.

   -  Business and industry:  Number of employees, total
      payroll, sales and receipts, products manufactured or sold.

   -  Housing and construction:  Value of new construction,
      numbers of owners and renters, property value or rent paid, housing
      starts, fuels used, mortgage costs.

   -  Farms:  Number, acreage, livestock, crop sales.

   -  Governments:  Revenues and expenditures, taxes, employment, pension
      funds.

   -  Foreign trade:  Exports and imports, origin and destination, units
      shipped.

   -  Other nations:  Population, birth rates, death rates, literacy,
      fertility.

 The other censuses, such as agriculture, retail trade, manufactures,
 and governments, are collected for years ending in "2" and
 "7." Surveys and estimates programs generate results as often as
 every month.

 Many of the monthly "economic indicators" that measure how the
 Nation is doing come directly or indirectly from the Census Bureau.
 Examples: employment and unemployment; housing starts; wholesale and
 retail trade; manufacturers' shipments, inventories, and orders;
 export and import trade; and sales of single-
 family homes.

 The other statistical activities of the Census Bureau are described
 below. Data users will find more information about them and
 descriptions of their data products in the annual Census Catalog
 and Guide. Also, special guides and brochures are prepared for
 most of them. Contact the Census Bureau's Customer Services for more
 information.

 Current Demographic and Housing Programs

 Two types of current programs complement the 10-year census:
 population estimates and surveys. The total population of the United
 States is estimated monthly; the population of States, counties, and
 metropolitan areas is estimated annually; and the population of places
 and other governmental units is estimated every 2 years. Projections of
 future population are made at the national and State levels.

 The Census Bureau's many household surveys update population and
 housing characteristics at the national level and sometimes for States
 and metropolitan areas, as well. These surveys also obtain many
 characteristics not included in the 10-year census. The Current
 Population Survey is taken monthly; the American Housing Survey
 national sample is taken biennially; the American Housing Survey
 metropolitan sample is taken in 44 areas, 11 per year in a 4-year
 cycle; most other surveys are annual or less frequent.

 Economic Censuses and Surveys

 The economic censuses provide statistics about business
 establishments once every 5 years, covering years ending in "2"
 and "7." The 1987 Economic Censuses include the censuses of
 retail trade, wholesale trade, service industries, transportation,
 manufactures, mineral industries, and construction industries. Also
 included are related programs, such as statistics on minority- and
 women-owned businesses, enterprise statistics, and censuses of economic
 activity in Puerto Rico and some of the outlying areas under U.S.
 jurisdiction.

 Several key statistics are tabulated for all industries covered in the
 censuses. They are number of establishments, number of employees,
 payroll, and measure of output (sales or receipts, and value of
 shipments or of work done). Other items vary from sector to sector.

 The Census Bureau also has programs that provide current statistics on
 such measures as total sales of particular kinds of businesses or
 production of particular products. These programs include monthly,
 quarterly, and annual surveys, the results of which appear in
 publication series such as Current Business Reports and
 Current Industrial Reports. The County Business Patterns
 program offers annual statistics based on data compiled primarily from
 administrative records.

 Agriculture Census and Surveys

 The agriculture census is conducted concurrently with the economic
 censuses. It is the only source of uniform agriculture data at the
 county level. It provides data on such subjects as the number and size
 of farms; land use and ownership; livestock, poultry, and crops; and
 value of products sold.

 Results of three surveys--the 1988 Farm and Ranch Irrigation Survey,
 1988 Census of Horticulture Specialties, and 1988 Agricultural
 Economics and Land Ownership Survey--are published in conjunction with
 the 1987 Census of Agriculture. Also, the Census Bureau regularly
 issues reports from a survey on cotton ginnings.

 Governments Census and Surveys

 The census of governments, also for years ending in "2" and
 "7," covers all types of governments: Federal, State, county,
 municipal (place), township (county subdivision), school district, and
 special district. It provides data on such subjects as number of public
 employees, payrolls, revenue, and expenditures.

 Annual and quarterly surveys cover the same principal subjects but
 generate data only for States and the largest local governments.

 Foreign Trade Statistics

 Monthly U.S. merchandise trade data compiled by the Census Bureau
 summarize export and import transactions and are based on the official
 documents filed by shippers and receivers. These figures reflect the
 flow of merchandise but not intangibles like services and financial
 commitments. The trade figures trace commodity movements out of and
 into the U.S. Customs jurisdiction, which includes Puerto Rico and the
 U.S. Virgin Islands as well as the 50 States and the District of
 Columbia. Data are published separately on trade between the United
 States and Puerto Rico, the U.S. Virgin Islands, and other U.S.
 possessions.

 Other Statistical Activities

 The Census Bureau also offers international data. It maintains an
 international data base which is available to the public on computer
 tape and is used to produce the biennial World Population
 Profile report. It prepares studies dealing with the demographic
 and economic characteristics of other countries and world regions.

 Statistical compendia are another important data product. These
 publications (sometimes also offered in machine-readable form) draw
 data from many sources and reorganize them for convenient use. The most
 widely used compendia are the annual Statistical Abstract of the
 United States, the County and City Data Book (published
 every 5 years), and the State and Metropolitan Area Data Book
 (published approximately every 4 years).

 Introduction

 There are three map series that relate to the geographic entities for which
 the Census Bureau provides statistics in the STF 1 data tapes.  The Census
 Bureau will reproduce copies of these maps on electrostatic plotters in
 response to orders received by Customer Services, Data User Services
 Division, Bureau of the Census, Washington, DC 20233 (301-763-4100).


 Map Descriptions

 County Block Maps

 County Block Maps--These maps depict each county and statistically equiva-
 lent area on one or more map sheets at various scales, depending on the
 county's areal size and the density of the block pattern.  (Most counties
 include multiple map sheets, including inset maps for densely settled
 areas.)  The maps display block numbers and feature identifiers as well as
 the boundaries, names, and codes for the legal and statistical entities in
 the county.  Each county includes an index map sheet that shows the
 locations of the map sheets comprising the county set.

 Census Tract/Block Numbering Area Outline Maps

 Census Tract/Block Numbering Area Outline Maps--These county-based maps
 depict the boundaries and codes of census tracts or block numbering areas,
 the features and feature names underlying the boundaries, and the
 boundaries and names of counties, county sub-divisions, places, and
 American Indian/Alaska Native areas.  Map scales vary to minimize the
 number of sheets.  The maps may include one or more insets for densely
 settled areas.  (The Census Bureau also intends to produce printed versions
 of these maps, for sale by the Government Printing Office (GPO), starting
 in 1992.)

 County Subdivision Outline Maps

 County Subdivision Outline Maps--These State-based maps depict the
 boundaries and names of all counties and statistically equivalent areas,
 county subdivisions, places, and American Indian/Alaska Native areas.  (The
 Census Bureau also will publish sectionalized versions of these maps in
 most 1990 census reports for each State.)

 This appendix provides the record layout for the machine-readable data
 dictionary file that accompanies each data tape.  This data dictionary was
 developed as a ``generic'' dictionary that, with some programming, could be
 converted for use with specific software packages.

 Equipment

 The two  basic pieces of equipment needed to use CD-ROM's are a
 microcomputer and a CD-ROM drive.  A printer is very useful but not
 essential.  Your microcomputer should be equipped with at least 640K random
 access memory (RAM).  While a hard disk is not required on your
 microcomputer, it is very useful.


 Software

 General Information

 Software is needed for accessing the CD-ROM as well as for accessing the
 data.

 MS-DOS 3.1 or higher is needed as your operating system if you have a CD-
 ROM reader.  You will also need DOS file manager software such as
 Microsoft's CD-ROM Extensions.  CD-ROM extensions is a collection of
 programs that enables the microcomputer to communicate with the attached
 CD-ROM drives.  You must have version 2.0 or higher of the Microsoft Exten-
 sions.

 If you already have a CD-ROM drive, you may not know whether it is equipped
 with file manager software like the CD-ROM extensions.  To find out, try
 signing on to your CD-ROM drive just as though it is a magnetic disk drive,
 and perform simple file management tasks, like listing the directory.  (For
 example, from the DOS prompt, type the command DIR and the letter used to
 designate the CD-ROM drive followed by a colon +e.g., C>DIR L:+ and press
 enter.)  If you get an error message, it may mean that you need to obtain
 and install CD-ROM extensions.

 CD-ROM Extensions

 Although all versions of CD-ROM extensions work basically the same way,
 installation procedures may vary slightly from one supplier to another.
 Many versions contain a program that will automatically install the
 software for you, after you have answered a few questions about the type of
 equipment that you plan to use.  Be sure to follow the instructions for
 installing CD-ROM Extensions that are provided with the software.

 The first step, if you are installing extensions without the aid of an
 automatic set-up program, is usually installing the device driver program
 and MSCDEX.EXE on your bootable disk.  For computers containing a hard
 drive, this usually means drive C.  The name of the device driver program
 varies from one version of extensions to another; one common practice of
 software developers is to name it after the brand of CD-ROM drive that it
 supports, e.g., HITACHI.SYS.  The device driver program and MSCDEX are
 frequently set up in separate subdirectories; however, this practice is not
 universal.

 The next step is to add a line to the CONFIG.SYS file to identify the
 device driver program.  This line typically looks something like this:

               DEVICE=\path\driver name/D:\driver alias/N:#
               For example:  device=\dev\hitachi.sys/D:MSCD001/n:1

 The driver name (e.g., hitachi.sys) and the driver alias should be provided
 by the set-up program or in the instructions that accompany the floppy disk
 containing the extensions software.  The symbol # at the end of the line
 should be replaced with the number of CD-ROM drives (up to 4) that will be
 hooked up to the microcomputer.

 The third step is to add a line to the AUTOEXEC.BAT file for running
 MSCDEX.EXE and assigning a letter to your CD-ROM drive.  Depending on your
 system configuration you may opt to set up one or more batch files to
 accomplish the same purpose.  If you add a line to the AUTOEXEC.BAT file,
 it will probably look something like this:

                   \path\MSCDEX.EXE/D:driver alias/M:8/L:L
                   For example:  \BIN\mscdex.exe/d:mscd001/m:12/L:L

 The driver alias, which is really the name that your system will use to
 identify the device driver, should be the same one that is named in your
 CONFIG.SYS file.

 The number following M: is the number of memory buffers allocated (usually
 8, but sometimes more).  The last letter, following the L:; designates the
 letter assigned to the CD-ROM drive.

 Though the final step is simple, it's also easy to overlook.  You must
 reboot the system in order to activate the changes that you've made to your
 CONFIG.SYS and AUTOEXEC.BAT.

 Once properly installed, the device behaves much like a read-only floppy
 diskette drive, and simple MS-DOS commands such as DIR are possible.  If
 the computer reports that the CD-ROM is "not High Sierra," you must first
 upgrade your Microsoft CD-ROM Extensions software to version 2.0 or later.

 Data Retrieval Software

 This CD-ROM contains data retrieval software.  This software was developed
 and tested on a COMPAQ Deskpro 286 with 640K RAM operating under MS-DOS
 3.31.  The software was compiled with Clipper (Summer '87).  There are no
 special display requirements.  Please note that the retrieval software will
 only run on IBM-compatibles operating under MS-DOS.

 To execute, type GO at the DOS prompt and ENTER.

           Example:  L:\>go

 The data on the CD-ROM are in dBase III+(TM) format.  Data in dBase
 III+(TM) format are recognized by many software packages including dBase
 IV(TM), Foxbase(TM), Clipper(TM), Supercalc V(TM), Quattro Pro(TM), and VP-
 Planner(TM).

 Users of other types of systems, such as the Apple Macintosh, have access
 to the files through support for ISO 9660 CD-ROMs.

 Converting to ASCII Files

 Users without database management software who wish to convert the files to
 ASCII can follow the code found in the README file on the CD-ROM.
