 Geographic Coverage 

 This abstract provides general information about the
 geographic coverage of STF 1.  For detailed information about
 hierarchy and splits across higher levels of geography, see
 the section "File Structure and Geographic Coverage."

 File A of STF 1 provides summaries for the State or State
 equivalent, counties or county equivalents, minor civil
 divisions (MCD's) or census county divisions (CCD's), places
 or place segments within MCD/CCD's and remainders of
 MCD's/CCD's, census tracts or block numbering areas (BNA's),
 and block groups (BG's) or, for areas that are not
 block-numbered, enumeration districts. These summaries are
 provided in hierarchical sequence.  Summaries are also
 presented on File A for places and congressional districts.
 (1980 congressional district data presented in STF 1 is for
 districts delineated for the 96th Congress.)

 File B provides summaries in hierarchical sequence for States,
 standard metropolitan statistical areas (SMSA's), nonSMSA
 remainder of State, counties, minor civil divisions (MCD's)
 within counties (available for 20 specified States), places
 within MCD's within counties (20 specified States) or places
 within counties (remaining 30 States), census tracts or block
 numbering areas (BNA's), and blocks or, for nonblock-numbered
 areas, enumeration districts (ED's).  Data for SMSA's which
 cross State lines are shown only for that portion in the
 particular State file.  Summaries are also provided for
 partially block-numbered portions of all geographic levels.

 File C is also referred to as the National file.  It has
 summaries for the following geographic levels:  United States,
 census regions, census divisions, States, standard
 consolidated statistical areas (SCSA's) , standard
 metropolitan statistical areas (SMSA's), and urbanized areas
 (UA's).  SCSA's, SMSA's, and UA's which cross State lines also
 have a record for the SCSA, SMSA, or UA portion within each
 State.  Summaries are included for counties, places of 10,000
 or more population, MCD's of 10,000 or more population in
 eleven selected States, and congression districts.

 Puerto Rico and other outlying areas are excluded from File C.

 Technical Description

    FILE SIZE:

    Metropolitan Map Series/Vicinity  Map Series (MMS/VMS).  This
    map series provides coverage of densely settled areas of
    selected counties and county equivalents. These maps are
    referred to as the Metropolitan Map Series (MMS) when the maps
    cover SMSA areas and as the Vicinity Map Series (VMS) when the
    maps cover areas not in an SMSA.  For a more detailed
    discussion of the MMS/VMS, see "1980 Census Maps."

    County Maps.  The maps cover all counties and county
    equivalents except where the Metropolitan Map
    Series/Vicinity Map Series (MMS/VMS) sheets cover an
    entire county.  Most county maps are based on maps
    supplied by State transportation or highway departments
    on which the Bureau has superimposed boundaries and
    identifiers for most areas for which data are tabulated.
    For a more detailed discussion on county maps, see
    "1980 Census Maps."

    Place Maps. Place maps are used for places not shown on
    MMS/VMS where most of the development is contained within
    the corporate limits of a municipality or within
    boundaries established for a census designated place
    (CDP).  For a more detailed discussion on place maps,
    see "1980 Census Maps."

 STF 1 File Description

 General Information

   Summary Tape File 1 (STF 1) is one of a series of summary data
   available from the 1980 census.  The file corresponds to a
   composite of the 1970 First Count and Third Count files and is
   composed of three parts -- STF 1A, STF 1B, and STF 1C.  Files STF
   1A and STF 1B are tentatively scheduled for separate release on a
   State-by-State basis in 1981-82 STF 1C will be issued after all STF
   1A and STF 1B files have been released.

 File Structure Geoqraphic Coverage

   For each geographic area there will be a 3276-character census
   logical record.  The census logical record is divided into two
   1638- character record segments to conform with ASCII standards.
   Each segment is identified in positions 99-100.  The first 102
   characters on each record segment provide geographic identification
   (positions 1 through 102 and 1639 through 1740) The next 150
   characters (positions 103 through 252) on the first segment provide
   additional geographic information and the suppression flags.  The
   remaining 1386 characters on the first segment (positions 253
   through 1638) and the remaining 1 536 characters on the second
   segment (positions 1741 through 3276) provide the data for the 59
   tables on STF 1.  For a concise description of the geographic
   coverage of each file in STF 1, see Appendix A.

 File STF 1a

 General Information for File STF 1A.  

 This file contains summary level data which
 follow a geographic hierarchy.  In file A, block groups (BG's)
 or enumeration distrits (ED's) are nested within a tract,
 block numbering area (BNA), or tract/BNA segment which in turn
 is sequenced within a place, then within a minor civil
 division (MCD) or census county division (CCD) , place
 segment, remainder of MCD or remainder of CCD, and, within a
 county or count equivalent. Data summaries are presented at
 each level. When a level of geography is split across the next
 higher level,  only the portion within the higher level will
 be shown on the summary.  For example, if tract 0001 is split
 between place, 0005 and 0010, the summary for the portion in
 place, 0005 will appear in the hierarachy with the place 0005
 summaries while the portion in place 0010 will appear with
 the place 0010 summaries.

       Place 0005
            Tract 0001 (part)
            :  Block group 1
            :  Block group 2
            :
            Tract  n

       Place 0010
            Tract 0001 (part)
               Block group 3

 In addition, place and congressional district summaries are
 presented separately from the hierarchically organized
 summaries.  Each summary is identified by a summary level
 code in positions 10-11 of the record as well as at the
 beginning of each segment. Figure 1 outlines the specific
 geographic hierarchy in STF 1A. Each indentation indicates
 the next lower level of the geographic hierarachy. Following
 Figure 1 is a discussion of each summary level in the hierarchy.

 Geographic Hierarchy of STF 1A

 State or State equivalent

     County or county equivalent

          Minor civil division/census county division (MCD/CCD)

              Place or place segment within MCD/CCD or remainder
              of MCD/CCD

                   Census tract or block numbering area (BNA) or
                   untracted segment, within place, place segment or
                   remainder of MCD/CCD

                        Block group (BG) or BG segment or Enumeration
                        district (ED)

 Place

 Congressional district

 The State record (Summary Level 04) contains a summary for the
 State or State equivalent.

 The county record (Summary Level 11) contains a summary for each
 county or county equivalent, including independent cities, within
 the State in FIPS code sequence.

 The minor civil division (MCD)/census county division (CCD) record
 (Summary Level 12) contains a summary for each MCD/CCD within the
 county in census code sequence.

 The place or remainder of MCD/CCD record (Summary Level 13)
 provides a summary for each place within an MCD/CCD in place code
 sequence. These may be places or, when places cross MCD/CCD
 boundaries, portions of places.  A remainder of MCD/CCD record will
 be generated only if there is a place in the MCD/CCD. This record
 will cover all areas outside of places and will have a pseudo place
 code of 9999.

 The combination of census tract/block numbering area (BNA) or
 untracted remainder of MCD/CCD (Summary Level 14), and block group
 (BG) (Summary Level 15) or enumeration district (ED) (Summary Level
 16) summaries will vary according to the situation. The four
 situations are as follows:

      Census tract or block numbering area (BNA)/block group (BG)
      1/ - When a census tract or BNA is entirely block numbered,
      a summary is shown for each tract/BNA or tract/BNA portion
      within MCD/CCD and place, place segment or remainder of
      MCD/CCD, and for each block group or block group segment
      within tract/BNA or tract/BNA portion.

      Census tract/ED 1/ - When the area is tracted but contains no
      blocks, a summary is shown for each tract or tract portion
      within MCD/CCD and place, place segment or remainder of
      MCD/CCD, and for each ED within tract.

      Not Tracted/ED - When an area is not tracted or not within a
      BNA, a summary is shown for each ED within the MCD/CCD and
      place, place segment, or remainder of MCD/CCD. A pseudo-tract
      code of 999999 will appear in the tract code field.

      Census tract/BG-ED 1/ - When a tract is partially block
      numbered, there will be a mixture of BG and ED summaries for
      the tract or the tract portion within MCD/CCD and place, place
      segment or remainder of MCD/CCD, BG summaries will precede
      those for ED's in this situation.

      The place total record (Summary Level 27) provides a summary
      for each place within the State. The place records are
      arranged by census place code.

 1/  When a tract, block numbering area, or block group crosses a
 place, MCD, or CCD boundary, there will be separate summaries for
 the portions within the high-level entities. Nototals for split
 tracts, BNA's, or block groups are provided.

 The Congressional district summary (Summary Level 33) contains
 summaries for each congressional district within the State arranged
 in numeric sequence.  These are the congressional districts
 designated for the 96th Congress.

 

 General Information for File STF 1B

 File STF 1B.  As with STF 1A, each logical-record segment of STF
 1B is identified by a summary level code in positions 10-11 of the
 record.  When the level of geography is split across the next
 higher level, only the portion within the higher level of geography
 will be shown.  (See example on STF 1A description above.)  The
 geographic hierarchy for STF 1B appears in Figure 2.

 * Blocked-portion record not shown when the geographic area
   being summarized is completely block-numbered.

 The State record (Summary Level 04) contains a summary for the
 State or State equivalent. It is followed by a record for the
 portion of the State which is block numbered, unless the entire
 State is block numbered. The block-numbered portion indicator is
 in character 21 of both record segments.

 The SMSA record (Summary Level 08) is a summary for each SMSA or
 portion of an SMSA within the State.  The records are in ascending
 FIPS SMSA code Sequence.  A remainder-of-State record summarizes
 the area outside of SMSA's within the State. This summary has a
 pseudo-SMSA code of 9999. A record is also provided for that
 portion of the SMSA or remainder-of-State which is block numbered.
 If the entire SMSA or SMSA part within a State is block numbered,
 the block-numbered portion record will not be presented.  The
 indicator for a block-numbered portion record is in character 21 of
 each record segment.

 The county record (Summary Level 17) is a summary for each county,
 county equivalent (including independent cities), and, in New
 England, portions of counties. These are arranged in FIPS county
 code sequence within SMSA; in New England, in census MCD code
 sequence, within county, within SMSA.  NonSMSA summaries will
 follow the nonSMSA remainder-of-State record.  There is also a
 record for the block-numbered portion of the county, county
 equivalent, or county part if the entire county is not
 block-numbered. The indicator for a block-numbered portion record
 is in character 21 of each record segment.

 The MCD summary (Summary Level 18) is provided for the following
 20 States:

  Connecticut   Massachusetts   New Hampshire   Pennsylvania
  Illinois      Michigan        New Jersey      Rhode Island
  Indiana       Minnesota       New York        South Dakota
  Kansas        Missouri        North Dakota    Vermont
  Maine         Nebraska        Ohio            Wisconsin

 The summary is not present in the remaining States. When present,
 these summaries appear in ascending MCD code sequence within the
 county.  There is also a summary for the block-numbered portion of
 the MCD for the 20 specified States. If the entire MCD is block
 numbered, the summary will not be present.  The indicator for a
 block-numbered portion record is in character 21 of each record
 segment.

 The place summary (Summary Level 19) provides a summary for each
 place segment within an MCD in the 20 States listed above.  In the
 remaining States, a summary is provided for each place or place
 segment within a county (Summary Level 23).  If place or place
 segment summaries are present for a given MCD or county, a summary
 is also presented for geographic areas outside the place reflecting
 either remainder-of-MCD or remainder-of-county, depending on the
 State being processed. These will have a pseudo-place code of 9999.
 These summaries are in ascending census place code sequence within
 the applicable area.  A summary is also provided for the block-
 numbered portion of the remainder-of-MCD andremainder-of-county area
 if the entire area is not block numbered.  The indicator for a
 block-numbered portion record is in character 21 of each record
 segment.

 The tract (BNA) summary (Summary Level 20 for 20 specified States,
 Summary Level 24 for the remaining States) is a summary for all of
 a tract or the portion of the tract within the place, place segment
 or remainder of MCD or county.  Areas which are not tracted have
 a pseudo-tract summary with a code of 999999.  A summary is also
 provided for the portion of the tract which is block numbered.
 This summary is not shown when the entire tract is block numbered.
 The indicator of a block-numbered portion record is in character
 21 of each record segment.  Where a tract (BNA) crosses a place or,
 in 20 specified States, MCD boundary, separate summaries pertain
 to each tract-part within the higher level entity.  There are no
 total records for split tracts or BNA's.

 The block summary (Summary Level 21 for 20 specified States,
 Summary Level 25 for the remaining States) provides data for each
 block within the tract.  When a block crosses a place or, in 20
 specified States, an MCD boundary, separate summaries are provided
 for each block part.

 The enumeration district (ED) summary (Summary Level 22 for 20
 specified States, Summary Level 26 for the remaining States) is
 generated if there are no blocks within an area or portion of an
 area.

 Suppression

 In order to maintain the confidentiality promised respondents and
 required by law, it is necessary for the Census Bureau to make sure
 that its public data, in print or on tape, do not disclose
 information about any individual. Therefore, the Bureau suppresses
 tabulations of characteristics of very small groups of people or
 housing units. On summary tapes, zeroes are entered in suppressed
 cells and flag fields which indicate suppression are shown on each
 record.  However, a zero in a cell does not automatically mean
 suppression. Only by checking the suppression flag can it be
 determined if the zero in a specific table is suppressed data or
 an actual count of zero.

 This discussion outlines the rules for suppression of 100-percent
 data, how its occurrence can be identified by the user, and how to
 handle it.

 No Suppression

 Several basic counts are never suppressed, even if there is a count
 of only one.  They are as follows:

                    Total population
                    Total housing units
                    Year-round housing units
                    Occupied units
                    Vacant year-round housing units
                    Count of persons and households in each
                       race or Spanish origin group

 Primary Suppression

 Suppression of Population Characteristics. Characteristics of
 persons other than race or Spanish origin (e.g., age, relationship)
 are shown only if there are 15 or more persons in the geographic
 area.  For example, on a record for an enumeration district with
 a population of 1 to 14 persons, population characteristics such
 as age and relationship are suppressed. Only counts for total
 population and the number of persons within specific race or
 Spanish origin groups are provided.

 However, when the geographic area being summarized has 15 or more
 persons, no suppression of population characteristics will occur--
 except possibly when tables are cross-classified by race or Spanish
 origin. The rules for this type of suppression are outlined below
 in Suppression of Tables Cross-Classified by Race or Spanish
 Origin. Please see Figure 5 below for a schematic of the
 suppression of population characteristics.

 Suppression of Year-round Housing Characteristics. Characteristics
 of year-round housing units which are not classified by occupancy
 status (e.g., number of rooms, plumbing facilities, etc.) are sup-
 pressed only when there are fewer than five year-round housing units
 in the geographic area being tabulated regardless of the

 Suppression of Family,Household,or Occupied Housing

 Suppression of Family, Household, or Occupied Housing
 Characteristics.  Characteristics of families, households, or
 occupied housing units are  shown if there are at least five
 occupied housing units within the  geographic area tabulated.

 Suppression of Owner or Renter Characteristics

 Suppression of Owner or Renter Characteristics.  Distributions
 of data for owners or renters are shown only when the number
 of owners is at least five and the number of renters is also
 at least five.

 Suppression of Tables Cross-Classified by Race/Spanish Origin

 Suppression of Tables Cross-Classified by Race or Spanish Origin.
 Population and housing characteristics cross-classified by race or
 Spanish origin are subject to an additional level of scrutiny. On
 this level the 15 person or five household criteria stated above
 are also applied to each race or Spanish origin category. For example,
 a table of race by age for geographic area which has 80 persons--40
 White, 20 Black, 14 American Indian, Eskimo and Aleut, and 6 Asian
 and Pacific Islanders shows data on age for Whites and Blacks.
 None of the data for these 2 groups are suppressed since they
 meet the criteria of having 15 persons of that race or Spanish
 origin group in the geographic area ("rule of 15"). Data for
 the other two race groups would not be shown.

 Individual cells of data for specific race or Spanish origin
 groups are never suppressed when there are 15 or more persons
 of that group in a geographic area unless required by
 complementary suppression (see below). For example, a table on
 age by race indicating 2 Blacks under 5 years, 10 Blacks 5 to 17
 years, 4 Blacks 18 to 64  years, and 4 blacks 65 years and over
 is presented since there are 15  or more total Blacks in the
 geographic area being tabulated.

 The population and housing suppression criteria are applied
 independently of one another.  For example, if there are 16
 Spanish origin persons but only four households with Spanish
 origin householders, the person characteristics will be shown
 but the family, household, and housing characteristics will
 be suppressed.

 Complementary Suppression

 In some cases complementary suppression is applied to prevent
 the derivation of suppressed data by subtraction.  For instance,
 when a table shows the number of persons in unit for all households
 and also for renters, there must be at least five owners and five
 renters for the renter data to be shown;otherwise the characteristics
 of the owners could be derived by subtracting renter data from data
 for all households.

 The following example illustrates complementary suppression as applied
 to a table of population characteristics cross-classified by race.

 EXAMPLE:  This is a hypothetical table of race by age.  The first
 column indicates the actual figures, while the second column
 indicates the data as they appear after applying both primary and
 complementary suppression.

        65 years and over      0                 0

 Comparing the columns, the actual count (col. 1) indicates more
 than 15 persons for both Whites and American Indians, Eskimos, and
 Aleuts, less than 15 Blacks, and 0 for both Asian and Pacific
 Islanders and Other.  Since there are fewer than 15 Blacks, data
 for this group are suppressed.  However, since only one race group
 is suppressed, complementary suppression rules must be applied.
 Since it would be a simple matter to determine the number of Blacks
 by subtracting the sum of Whites and American Indians, Eskimos, and
 Aleuts from the total, it is necessary to suppress the data for
 American Indians, Eskimos, and Aleuts as well (complementary
 suppression).  Column 2 indicates the figures which would
 appear with an indication whether suppression is primary or
 complementary.  It should be noted that "other" is the first
 race category to which complementary suppression is applied
 if there are persons in that category.  This complementary
 suppression may not always be obvious because many tables do
 not present data about "other races" directly, but require
 them to be derived by subtraction.

 Examples of Suppression

 The following example shows four tables from the STF 1 Data
 Dictionary.  The first table (Table 7) will never be
 suppressed because it is a basic count.  The second table
 (Table 10) will only be suppressed if there are fewer than 15
 persons in the geographic area being summarized.  The third
 table (Table 19) will be suppressed if there are fewer than
 five occupied housing units in the tabulation area.  The
 fourth table (Table 12) will have portions suppressed for race
 groups with fewer than 15 members in the geographic area
 tabulated or if complementary suppression is applied.

 Programming with Suppression

 Suppressed data cells contain zeroes.  To distinguish between
 zeroes as suppression and zeroes as valid data, occurrences of
 suppression are identified by a series of flag fields in the
 geographic identification portion of each logical record.
 Programmers developing software should include procedures to check
 these fields for the presence of suppression and, if necessary, to
 flag the output of any cumulation which includes one or more
 suppressed fields.

 In reviewing the data dictionary, the programmer can determine
 which suppression flags indicate suppression for particular tables
 by checking either the table description or the flag description.
 An example of each is on the following page.

                      Example: The boxed illustration below is the
                               table description as it appears in
                               the data dictionary.  The other
                               portion illustrates the suppression
                               flag to which the table description
                               refers.

                          A 1 in this field indicates
                          suppression because there
                          are fewer than five housing
                          units in the renter-occupied

                          complementary suppression is

 Figure 7 which follows, lists each suppression flag, its location
 within the record, and the tables or cells within tables which are
 affected when suppression is applied. The suppression flag field
 which applies to each table or portion of a table is also identified
 in the table description in the data dictionary.The flags are located
 in the geographic identification section of each record segment in
 positions 205-225.

 Evaluating the Effect of Suppression

 In most cases, suppressed data values are small (fewer than5 or
 15) except where a large population is affected by complementary
 suppression.  Therefore, in certain noncritical applications,
 users may simplify programming operations by ignoring suppression
 and treating suppressed cells as zero cells.

 However, if the user is adding up blocks or enumeration districts
 to derive tables for user-defined areas, ignoring suppression can
 result in a downward bias in the totals.  The impact of that down-
 ward bias can be gauged by comparing sums associated with tables
 subject to suppression with nonsuppressed sums for the same
 aggregation of areas. For example, if age data for Blacks from
 table 12 are added together for a group of blocks, the impact of
 suppression can be gauged by adding the ages together to get a
 total, and comparing that number to the number of Blacks derived
 from summary table 7 for the same group of blocks (table 7 is not
 subject to suppression).

FOOTNOTES

 01  The count of households, in the complete-count tabulations by
    definition equals the number, of occupied housing units.  For
    this documentation the term "Household" is used unless the
    matrix is stratified by a housing item such as tenure,
    plumbing facilities, etc., in which case, the term `Occupied
    housing unit' is used.

 02  Vacant seasonal/ migratory units are excluded frown all
     other tabulation matrices.

 03  For data tabulated on a 100-percent basis includes all persons
     in the category "Other." For data tabulated from the sample,
     excluded those persons who have write-in entry of an Asian and
     Pacific Islander group in the "Other" category.

 04  "Asian and Pacific Islander," in the 100-percent tabulations,
     includes "Japanese," "Chinese," "Filipino," "Korean," "Asian
     Indian," "Vietnamese," "Hawaiian," "Guamanian," and "Somoa,"
     "Asian and Pacific Islander," in sample tabulations, includes
     the groups listed above and those persons who have a write-in
     entry of an Asian or Pacific Islander group in the "Other" category.

 05  Relatives include householder, spouse, and the questionnaire
     categories: "Son/daughter," "Brother/sister," "Father/mother,"
     and "Other relative." Tabulations of "Other relatives" include
     all categories not shown separately in the matrix.

 06  "Nonrelatives" include the questionnaire catagories: "Roomer,
     boarder," "Partner, roommate," "Paid employee," and "Other
     nonrelative." Tabulations of "Nonrelatives" include all
     categories not shown separately in the matrix.

 07  Tabulations of "Persons in household" based on 100-percent
     data by definition are the same as tabulations of "Persons
     in unit."  The phrase "Persons in household" is used unless
     the matrix is stratified by a housing item such as tenure,
     plumbing facilities, etc., in which case, the phrase "Persons
     in unit" is use Tabulations of "Persons in household" and
     Persons in unit" based on sample data are not necessarily
     the same because of differences in the procedures used to
     inflate sample population and housing data.

 08  A "Child of householder" includes any son, daughter stepchild,
     or adopted child of the householder.  An "Own child of house-
     holder" is a never-married child under 18 years of age who
     is a son, daughter, stepchild, or adopted child of the
     householder. "Related children" include not only own children
     but also all other family members, regardless of marital status,
     who are under 18 years old, except the householder or spouse.
     Foster children are included in the "Nonrelative" category.

 09  Vacant housing units include the questionnaire categories:
     "For rent," "For sale only," "Rented or sold, not occupied,"
     "Held for occasional use," and "Other vacant." Tabulations of
     "other vacants" include all categories not shown separately
     in the matrix.

 10  This aggregate, along with the relevant count, will permit the
     computation of a mean. For example, the aggregate value for
     specified owner-occupied noncondominiumunits will yield the mean
     value when divided by the count of specified owner-occupied
     noncondominium units, and theaggregate rooms for occupied and
     vacant year-round units divided by the count of occupied and vacant
     year-round units yields mean rooms. (See footnote 14 prior to
     computing mean value or price asked).

 11  Value and price asked are tabulated separately for noncondominium
     and condominium units.

     The noncondominium value distribution is restricted tocertain kinds
     of "owner-occupied" units; the noncondominium price asked distribu-
     tion is restricted to certain kinds of "vacant-for-sale-only" units.
     The following are excluded from the tabulations on value and price
     asked for noncondominium units:

       a.  Units at an address with two or more units
       b.  Units on 10 or more acres
       c.  Units with a commercial establishment or medical
             office on the property
       d.  Mobile homes or trailers

     The condominium value distribution is tabulatedfor all "owner-
     occupied" condominium units; the condominium price asked distribu-
     tion is tabulated for all "vacant-for-sale-only" condominium units.

 12  Contract rent is tabulated for all "renter-occupied" units
     except one-family houses on a property of 10 or more
     acres.  Rent asked is tabulated for all "vacant-for-rent"
     units except one-family houses on a property of 10 or more
     acres. Units tabulated in the "No Cash Rent" category are
     all occupied housing units reported as "No Cash Rent"except
     one-family houses on 10 or more acres.

 13  Lacking complete plumbing (facilities) for exclusive use
     includes:  Complete plumbing (facilities) but also used by
     another household, some but not all plumbing facilities,
     or no plumbing facilities.

 14  Multiply the aggregate value and price asked by $250 to obtain
     the true value or price asked. The tabulation was scaled by a
     factor of $250 for tally purposes.

 15  Allocations of marital status for persons under 15 years old
     are not allocated in "Persons with one or more items allocated.

 16  "Year-round housing units with one or more housing items
     allocated" includes allocations of "Units at address,"
     "Access," "Plumbing facilities," "Rooms," "Tenure", "Condominium
     Status," "Acreage of property," "Commercial establishment or
     medical office," "Value" or "Price asked," "Contract rent" or
     Rent asked," "Vacancy indicator," "Vacancy status," "Boarded up
     status," and  "Duration of vacancy."


HOW TO USE THE DATA DICTIONARY

 General Information

 The data dictionary contains complete information regarding geographic codes,
 table information, and a detailed table layout.The following is an outline of
 information provided in both the geographic and table identification portions
 of the file.

 Geographic Identification

 The first line of each geographic identification variable gives the name,
 size/scale, begin position, relative begin position, and the variable label.
 Following those items, on subsequent lines, are any applicable notes and
 value codes.  Each of these items is defined below.

    1.Name.  This is an arbitrarily assigned 8-character identifier.  It may
      be a mnemonic such as "STATE" or "EDNUMBER", or a sequential identifier
      such as "TAB1", "TAB2", etc.

    2.Size/Scale.  The size of a data item is given in characters. The scale
      of a data item is given in powers of 10.  Implied decimals or
      multipliers (in powers of ten only) are indicated by a "-" or a "+"
      followed by a number.  For example, 123.45 would appear on the data
      tape as 12345, and the size/scale value would be 5/-2.  A number
      recorded in thousands(12,345,000 for example)would appear on the data
      tape as 12345 and the size/scale value would be 5/+3.  Scale factors
      which are not a power of ten are identified in the notes following the
      description and in the footnotes.

    3.Begin.  This is the location in the data record of the first character
      of the data item.

    4.Relative Begin.  This value indicates the beginning location of a data
      item within the segment files with segmented records.  For example, STF
      1 has a census logical record length of 3276 characters which is
      segmented into two segments of 1638 characters each.  The data item
      beginnng in position 1639 of the census logical record would have a
      relative begin value of 1.

    5.Date Type.  The data type indicates whether the data item is
      alphanumeric (A) or numeric (N).

    6.Description.  Following the Data Type is a description of the data
      item.  This heading is not labeled on the data dictionary.  This
      section also provides any relevant notes or footnote references.  In
      addition, any value codes necessary for the data item are listed and
      labeled here.

 Table Identification

 The documentation of tables begins with the name, size/scale, begin position,
 relative begin position for the table, data type, and the number of cells.
 This information is followed by the table title,applicable suppression flags,
 universe definition, applicable footnotes, stratifier identification, and a
 listing of the cells.  These items are defined below.

 number, which identifies
 the data item as a table
 for CENSPAC.  The "TABLE
 A15" is generated by the
 CENSPAC Documentor
 program.

                       This item identifies the location
                       in the data record, relative to
                       the beginning of the current
                       segment, of the first cell in the
                       table.

 Table Title.  The title of the table identifies the stratifiers used in the
 table, and in parentheses following each stratifier the number of categories
 for that stratifier.  For example, this title indicates that there are two
 categories of tenure and five categories of race of householder identified in
 the table.

 Suppression Flags.  This section of the table documentation identifies by
 name any applicable suppression flags and the cells to which they apply.

 Universe.  The universe identifies the unit of observation for the table.
 For example, the cells in this table are counts of occupied housing units.
 Footnotes.  This section identifies any footnotes, listed at the end of the
 data dictionary, which apply to the table.

 Stratifiers.  This section lists the stratifiers used in the table, in the
 order that they appear on the data tape.  For example, this table begins with
 the first category of tenure cross classified by the five categories of race
 of householder.  This is followed by the second category of tenure cross
 classified by the five categories of race of householder.

STF1 Data Dictionary Footnotes

 01  The count of households in the complete-count tabulations by definition
     equals the number of occupied housing units. For this documentation the
     term "Household" is used unless the matrix is stratified by a housing
     item such as tenure, plumbing facilities, etc., in which case, the term
     "Occupied housing unit" is used.

 02  Vacant seasonal/migratory units are excluded from all other tabulation
     matrices.

 03  For data tabulated on a 100-percent basis, includes all persons in the
     category "Other."  For data tabulated from the sample, excludes those
     persons who have a write-in entry of an Asian and Pacific Islander
     group in the "Other" category.

 04  "Asian and Pacific Islander," in the 100-percent tabulations, includes
     "Japanese," "Chinese," "Filipino," "Korean," "Asian Indian,"
     "Vietnamese," "Hawaiian," "Guamanian," and "Samoan." "Asian and Pacific
     Islander," in sample tabulations, includes the groups listed above and
     those persons who have a write-in entry of an Asian or Pacific Islander
     group in the "Other" category.

 05  Relatives include householder,spouse, and the questionnaire categories:
    "Son/daughter," "Brother/sister," "Father/mother," and "Other relative."
     Tabulations of "Other relatives" include all categories not shown
     separately in the matrix.

 06  "Nonrelatives" include the questionnaire categories: "Roomer, boarder,"
     "Partner, roommate," "Paid employee," and "Other nonrelative."
     Tabulations of "Nonrelatives" include all categories not shown
     separately in the matrix.

 07  Tabulations of "Persons in household" based on 100-percent data by
     definition are the same as tabulations of "Persons in unit." The phrase
     "Persons in household" is used unless the matrix is stratified by a
     housing item such as tenure, plumbing facilities, etc., in which case,
     the phrase "Persons in unit" is used.  Tabulations of "Persons in
     household" and "Persons in unit" based on sample data are not
     necessarily the same because of differences in the procedures used to
     inflate sample population and housing data.

 08  A "Child of householder" includes any son, daughter, stepchild, or
     adopted child of the householder.  An "Own child of householder" is a
     never-married child under 18 years of age who is a son, daughter,
     stepchild, or adopted child of the householder.  "Related children"
     include not only own children but also all other family members,
     regardless of marital status, who are under 18 years old, except the
     householder or spouse.  Foster children are included in the
     "Nonrelative" category.

 09  Vacant housing units include the questionnaire categories:  "For rent,"
     "For sale only," "Rented or sold, not occupied," "Held for occasional
     use," and "Other vacant."  Tabulations of "Other vacants" include all
     categories not shown separately in the matrix.

 10  This aggregate, along with the relevant count, will permit the
     computation of a mean.  For example, the aggregate value for specified
     owner-occupied noncondominium units will yield the mean value when
     divided by the count of specified owner-occupied noncondominium units,
     & the aggregate rooms for occupied and vacant year-round units divided
     by the count of occupied and vacant year-round units yields mean rooms.
     (See footnote 14 prior to computing mean value or price asked.)

 11  Value and price asked are tabulated separately for noncondominium and
     condominium units.
     The noncondominium value distribution is restricted to certain kinds of
     "owner-occupied" units; the noncondominium price asked distribution is
     restricted to certain kinds of "vacant-for-sale only" units.  The
     following are excluded from the tabulations on value and price asked
     for noncondominium units:
          a.  Units at an address with two or more units
          b.  Units on 10 or more acres
          c.  Units with a commercial establishment or medical office on the
              property
          d.  Mobile homes or trailers
     The condominium value distribution is tabulated for all "owner-
     occupied" condominium units; the condominium price asked distribution
     is tabulated for all "vacant-for-sale only" condominium units.

 12  Contract rent is tabulated for all "renter-occupied" units except
     one-family houses on a property of 10 or more acres.  Rent asked is
     tabulated for all "vacant-for-rent" units except one-family houses on a
     property of 10 or more acres.  Units tabulated in the "No Cash Rent"
     category are all occupied housing units reported as "No Cash Rent"
     except one-family houses on 10 or more acres.

 13  Lacking complete plumbing (facilities) for exclusive use includes:
     Complete plumbing (facilities) but also used by another household, some
     but not all plumbing facilities, or no plumbing facilities.

 14  Multiply the aggregate value and price asked by $250 to obtain the true
     value or price asked. The tabulation was scaled by a factor of $250 for
     tally purposes.

 15  Allocation of marital status for persons under 15 years old are not
     included in "Persons with one or more items allocated."

 16  "Year-round housing units with one or more housing items allocated"
     includes allocations of "Units at address," "Access," "Plumbing
     facilities," "Rooms," "Tenure," "Condominium status," "Acreage of
     property," "Commercial establishment or medical office," "Value" or
     "Price asked," "Contract rent" or "Rent asked," "Vacancy indicator,"
     "Vacancy status," "Boarded up status," and "Duration of vacancy."
OVERVIEW - 1980 CENSUS SUMMARY TAPE PROGRAM

 General Information

 Computer-readable data from the 1980 census include both  summary
 data  and  microdata.   Summary  data  include Summary Tape Files
 (STF's) 1 to 5, which are generally comparable to the First Count
 through Sixth Count files from the 1970  census.   In addition to
 the files in the STF series, other summary data to be released by
 the Bureau include a P.L. 94-171 Population Counts file  for  use
 in  reapportionment/redistricting  (released  in  February/March,
 1981),  various  subject  report  files,  and  the  Master   Area
 Reference  File  which  provides  geographic items from STF 1 and
 selected  population  and  housing items.   All  of  these  files
 contain  data  summarized  to  various   levels   of   geography.
 Microdata  files,  on  the  other  hand,  contain disclosure-free
 household  and person records from the census.  These  files  are
 similar to the 1970 Public Use Sample files and will be available
 some time after the release of STF 4.

 Content and Geographic Coverage of summary Tape Files

 Summary Tape  Files vary by summary level of geography, detail of
 information, and hether they include 100-percent or sample data.
 STF's 1 and 2 provide  data  based on the set of census questions
 asked  of  all  persons  and  housing   units.   These  data  are
 100-percent  data. STF's 3, 4, and 5 are based  on  sample  data.
 These data are  estimates  based  on the responses of a sample of
 the  population  and  housing units and  contain  more  extensive
 housing and population  information.  In  1980, the sampling rate
 was 1 in 2 in governmental units with less than 2,500 inhabitants
 and   1   in  6  elsewhere.   Overall  the  sampling   rate   was
 approximately  1  in  5.   The Bureau's 1977 population estimates
 were used to determine the sampling rate for a given area.

 The geographic detail of STF 1 is the maximum possible detail
 available from the census:   data for individual blocks in block-
 numbered   areas   and   for   enumeration    districts   outside
 block-numbered areas.  The lowest level of geography  provided by
 STF  2  is  census  tract,  or minor civil division/census county
 division (MCD/CCD) and places  of  1,000  or  more inhabitants in
 nontracted areas.  The lowest level for STF 3 is  the block group
 or enumeration district, while the smallest geographic  unit  for
 STF  4  is  census  tract  or MCD/CCD and places of 2,500 or more
 inhabitants in nontracted areas.  STF 5's lowest geographic level
 is the standard metropolitan  statistical  area  (SMSA),  central
 city(ies), places of 50,000 or more inhabitants, and counties  of
 50,000  or  more  inhabitants.   Figure  8  on the following page
 details the geographic levels in each Summary Tape File.

 For comparison purposes, STF 1 is similar in subject matter and
 geographic detail to the First and Third Count  files  for  1970.
 STF's  2  and  4  are  roughly  comparable to the 1970 Second and
 Fourth Counts, respectively.  STF  3  is  comparable  to the 1970
 Fifth Count, while STF 5 corresponds to the 1970 Sixth Count.  To
 summarize,  STF  1  contains  more  detailed  geography  but less
 subject matter detail than STF 2.

 4/  STF 3B, which was planned to provide 5-digit ZIP Code tabulations,
     has been cancelled.  However, private groups are currently discuss-
     ing the  possibility of their funding Census Bureau tabulation of
     these data. The geographic structure of such a file will be decided
     at a later date.

 Similarly,  STF  3  contains  more detailed  geography  but  less
 subject matter detail than STF 4.  STF's 1 and 2 contain complete
 count  data,  while  STF's  3  and 4  contain  sample  estimates.
 Finally, STF 5 contains sample estimates  aggregated  to a higher
 level of geography than the other files, but which are  presented
 in the most subject matter detail.
 1980 Census Maps

 Users  may  need certain types of maps for the geographic area(s)
 they are extracting  from  the  file(s).  To determine which maps
 best  define  the  geographic  area(s),  compare  the  geographic
 coverage of each file (see Appendix  A)  with  the description of
 each type of 1980 census map(see below).

 The maps used in conjunction with the above summary tape files
 consist of five basic types:  county maps, place maps, place-and-
 vicinity maps, American Indian reservation maps, and Metropolitan
 Map  Series  (MMS)  or  Vicinity  Map  Series  (VMS).    Ordering
 information  for  these  maps  may  be  obtained  from  Data User
 Services  Division,  Customer  Services  (Maps),  Bureau  of  the
 Census, Washington, D.C.  20233.

 All five map types have several characteristics in common:

     --To improve legibility, most 1980 maps are at a larger scale
          than were the comparable 1970 maps.

     --Symbols  used for the various boundaries are consistent for
          all five types of maps.

     --Names, identifying  numbers, and boundaries are shown where
          appropriate on all maps for counties, minor civil
          divisions (MCD's) or census county divisions (CCD's),
          places, American Indian reservations and Alaska Native
          villages, census tracts or block numbering areas (BNA's)
          where present, enumeration districts (ED's) (in those
          areas which are not block numbered), and blocks.

     --All maps show metric, feet, and mile scales.

     --All maps containing  block-numbered areas will be available
          from the U.S. Government Printing Office.

 The following paragraphs present a brief description of each type
 of  map.  The inclusion of the  maps  with  various  1980  census
 products reflect the Bureau's plans as of July 1981.

 County Maps.  County maps are the backbone of the Bureau's map
 coverage.  Theoretically, with a complete set of these maps the
 overall picture of the census geographic framework for the entire
 United  States  and  its  possessions is shown.  Most maps in the
 county series are at a scale  of 1 inch: 1 mile.  Most county maps
 are created by superimposing boundaries  for most areas for which
 data are tabulated on base maps supplied by  State transportation
 or highway departments. There are approximately 5,500 county map sheets
 for 1980.  The following geographic area boundaries  are  defined  on
 county  maps  where  appropriate:   State,  county,  minor  civil
 divisions  (MCD's)  or  census  county divisions (CCD 5), places,
 American Indian reservations, census  tracts  or  block numbering
 areas  (BNA's),  and  enumeration  districts  (ED's) or  numbered
 blocks.  In addition, the location of Alaska Native  villages are
 indicated.

 Place  Maps.   For places not covered on MMS or VMS sheets  where
 most of the development  is contained within the corporate limits
 of a municipality or within  the  boundaries  established  for  a
 census  designated place (CDP) , the Bureau uses place maps.  The
 scale of  the place maps varies from place to place.  As with the
 county maps,  most  are  created  by superimposing boundaries for
 most areas for which data are tabulated  on base maps supplied by
 local or State governments. On the county  map,  shading is added
 to  indicate the area covered by the place map; i.e.,  the  place
 map is  regarded  as an inset to the county map.  There are about
 12,300 place map sheets for 1980.  The geographic area boundaries
 defined on place maps are the same as for county maps.

 Place-and-Vicinity  Maps.   For  places not covered on MMS or VMS
 sheets which have areas of fairly  dense  development outside the
 corporate  limits  of  a municipality or outside  the  boundaries
 established for a CDP, the  Bureau  uses place-and-vicinity maps.
 Also  included in this category are maps  of  places  which  have
 parcels  of land that are not part of the city but are completely
 surrounded by the city and where two or more places appear on the
 same map sheet.   In  all other respects, place-and-vicinity maps
 have the same characteristics  as  place maps.  As with the place
 maps, all area covered by the place-and-vicinity map is shaded on
 the county map and the place-and-vicinity map is considered to be
 an   inset   to   the   county  map.   There  are   about   3,300
 place-and-vicinity map sheets  for  1980.   The  geographic  area
 boundaries  defined on place-and-vicinity maps are the same as those
 specified for county maps.

 Indian Reservation  Maps.   The  Census Bureau developed separate
 maps  for  18 American Indian reservations  which  could  not  be
 depicted adequately  on  county maps; these maps are very similar
 in format of county maps.   There  are  approximately 75 American
 Indian reservation maps and these maps are  special insets to the
 county  maps.  The geographic area boundaries  defined  on  these
 maps are the same as those specified for the county maps.

 Metropolitan  Map  Series/Vicinity  Map Series (MMS/VMS). For the
 nation's major built-up areas, the Bureau  has  developed its own
 maps to provide uniform coverage of the densely settled  portions
 of  the  counties  involved.   These  maps are referred to as the
 Metropolitan Map Series (MMS) when the  maps  cover SMSA counties
 and  as the Vicinity Map Series (VMS) when the maps  cover  areas
 which  are not in an SMSA.  (In a few instances, these map sheets
 entirely  cover  a  county,  in which case no separate county map
 exists.)  The  predominant  scale  for  the  MMS  and  VMS  is  1
 inch:1,600 feet.In selected areas with very dense development,some
 sheets are at 1 inch:800 feet;conversely, some sparsely settled areas
 are mapped at 1 inch:3,200 feet.The MMS and VMS are considered to be
 insets to the county maps.The areas covered by MMS and VMS are shaded
 on county maps. There are about 10,400 MMS and VMS sheets  for 1980.
 The geographic area boundaries defined on the MMS are the same as
 those  specified  for  county  maps,  but  also include urbanized
 areas.

 In addition to the five types of maps described  above, there are
 a number of "outline" maps (maps that do not show  any data, only
 the  areas  to  which data can be related) that are prepared  and
 published as part  of  the various printed report series.  As was
 the case with the maps previously described, the maps included in
 the printed reports share  common  characteristics.   Both metric
 and mile scales are shown.  Map scale and content are similar  to
 1970  except  where  noted  below; however, presentation has been
 improved  to  make the maps more  readable  and  consistent  from
 series to series.

 The County Subdivision  Map  Series  consists of at least one map
 page  for each State showing the names  and  boundaries  for  the
 State,  each  component county, the minor civil divisions (MCD's)
 or  census  county   divisions  (CCD's),  and  all  places,  both
 incorporated and census  designated.   For most States, the scale
 of  the maps requires that they be presented  in  sections.   For
 1980,  the  boundaries  (not  just  the locations) of places with
 fewer than 2,500 inhabitants are shown  for  the  first time.  In
 addition, the name(s) of adjoining State(s) are shown  along with
 a  mark to indicate where the State boundaries intersect.   These
 maps  are  based  on  the  State base maps of the U.S. Geological
 Survey (USGS) National Mapping Program.  Single-sheet versions of
 the county subdivision map series are published at the USGS scale
 of 1:500,000 (1 inch equals  about 8 miles) for all States except
 Alaska and the outlying areas, and may be fitted together to form
 multi-State maps.  These maps  appear  in  PC80-1-A.   For  those
 States  in  which  American  Indian reservations or Alaska Native
 villages are located, a special version of the county subdivision
 map showing these entities appears in PC80-1-B and HC80-1-A.

 The Urbanized Area Outline Map Series consists of one or more map
 sheets for each urbanized area  (UA)  defined on the basis of the
 1980  census results.  The names and boundaries  of  all  States,
 counties,  MCD/CCD's,  and places in the area are shown, plus the
 extent of territory defined  as "urbanized." These maps appear in
 PC80-1-A.  In 1980, the report  for each State containing part of
 a multi-State UA will include the map for the entire UA.

 The State SCSA/SMSA Map Series shows county names and boundaries,
 ames and locations of all places  with a population of 25,000 or
 more or designated as the central city of an SMSA, and names and
 boundaries of standard consolidated  statistical  areas (SCSA's),
 and  standard  metropolitan  statistical  areas (SMSA's)  in  the
 State.   For  1980,  the  name  of the capital of  the  State  is
 underlined.  These maps appear in PC80-1-A, B, C, D; HC80-1-A, B;
 and HC80-2.

 Map sets will be printed for all block-numbered areas, grouped by
 SMSA and nonSMSA balance-of-State.

 In addition to printed copies of the county, place, place-and-
 vicinity,  and  Metropolitan  Map  Series/Vicinity   Map   Series
 (MMS/VMS)  sheets  having block-numbered areas, there will be  an
 index map depicting the extent of the block-numbered area for the
 SMSA and State.  The SMSA Index to Block Numbered Areas Maps will
 show the extent of the SMSA; county, MCD/CCD, and place names and
 boundaries; and the extent of block-numbered area within the SMSA
 shown by means of shading.   The  State  Index  to Block-Numbered
 Areas  Maps  were  prepared  by superimposing the extent  of  all
 block-numbered-areas in the State  over  the  county  subdivision
 map.  This index map will also show the boundaries of the SMSA(s)
 in  the  State so that the reader can determine whether the  data
 for any block-numbered  area  in the State are available with the
 SMSA tabulations or the balance-of-State tabulations.

 The Census Tract Outline Map Series  covers each of the areas for
 which tracts have been defined in 1980.  These maps show the
 boundaries and code identification numbers  for  each  tract; the
 names   of  streets  or  other  features  used  as  census  tract
 boundaries; and the names and boundaries for counties, MCD/CCD's,
 and all places  (not  just those over 25,000 as in 1970).  Street
 detail within the tracts is not shown.  Separate insets of larger
 scale  than the base maps  are  included  for  densely  developed
 areas; however,  fewer insets are used than in 1970.  Scale varies
 from map to map.   For  1980,  tract outline maps are planned for
 tracted counties outside SMSA's.

TECHNICAL INFORMATION (STF1)

 Nonsampling errors

 Since 1980 population counts shown  in  this  file were tabulated
 from the entries for persons on all questionnaires,  these counts
 are not subject to sampling error, In any large-scale statistical
 operation such as a decennial census, human and mechanical errors
 do  occur.  These  errors are commonly referred to as nonsampling
 errors.  Such errors include failure to enumerate every household
 or  person  in  the  population,   not   obtaining  all  required
 information from respondents, obtaining incorrect or inconsistent
 information, and recording information incorrectly.   Errors  can
 also  occur during the field review of the enumerdtors' work, the
 clerical handling of the census questionnaires, or the electronic
 processing of the questionnaires.

 In an attempt  to  reduce  various types of nonsampling errors in
 the 1980 census, a number of  techniques  were  introduced on the
 basis  of experience in previous censuses and in tests  conducted
 prior to  the  census.  These quality control and review measures
 were  utilized throughout  the  data  collection  and  processing
 phases  of the census to minimize undercoverage of the population
 and housing  units  and  to keep the errors at a minimum.  As was
 done after the 1950, 1960, and 1970 censuses, there were programs
 at the conclusion of the 1980  census  to measure various aspects
 of the quality achieved in the census, Reports on many aspects of
 the 1980 census evaluation program will  be  published as soon as
 the appropriate data are accumulated and analyzed.

 A major component of the evaluation work is to ascertain, insofar
 as possible, the degree of completeness of the  count  of persons
 and housing units.  The Census Bureau has estimates that the 1970
 census  did  not count 2.5 percent of the population.  For  1980,
 the Census Bureau's extensive evaluation program will encompass a
 number of different  approaches  to  the  task  of estimating the
 coverage  of  the census.  Although these studies have  not  been
 completed  at  the  time  of  this  file's  release,  preliminary
 estimates indicate  that  the  rate  of undercoverage in the 1980
 census was reduced from 1970 census levels.

 Editing and Allocation of Data Items

 The objective of the processing operation  is to produce a set of
 statistics  that  describes  the  population  as  accurately  and
 clearly as possible, To meet this objective, certain unacceptable
 entries and blank items were edited.

 Editing, In the field, questionnaires were reviewed for omissions
 and  certain inconsistencies by a census clerk or  an  enunerator
 and, if  necessary,  a followup was made for missing information.
 In addition, a similar  review  of questionnaires was done in the
 central processing offices. As a rule, however, editing was performed
 by hand only when it could not be done effectively by machine.

 As  one  of  the  first  steps  in  computerized   editing,   the
 configuration  of  marks  on the questionnaire column was scanned
 electronically to determine  whether it contained information for
 a  person  or merely spurious marks.   If  the  column  contained
 entries  for   at   least   two   of  the  basic  characteristics
 (relationship, sex, race, age, marital  status,  Spanish origin),
 the inference was made that the marks represented  a  person.  In
 cases  in  which two or more basic characteristics were available
 for only a portion  of  the people in the unit, other information
 on  the questionnaire provided  by  an  enumerator  was  used  to
 determine  the total number of persons.  Names were not used as a
 criterion of  the  presence  of  a  person because the electronic
 scanning was unable to distinguish an entry in the name space.

 Allocation.  Allocations, or assignments  of  acceptable codes in
 place  of  unacceptable entries, 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  the person or housing
 unit.  The usefulness of the data is considered  to  be  enhanced
 through the assignment of acceptable codes in place of blanks  or
 unacceptable entries.

 For  housing data, the assignment is based on related information
 reported for the housing unit or on information reported for a
 similar  unit  in  the  immediate  neighborhood.  For example, if
 tenure for an occupied unit is omitted  but  a  rental  amount is
 reported for that unit, the computer edits tenure to "rented  for
 cash  rent." On the other hand, if the unit is reported as rented
 but the  amount of rent is missing, the computer assigns the rent
 from the preceding  renter-occupied unit that had a rental amount
 reported.

 The  general  procedure   for  changing  unacceptable  population
 entries is to assign an entry  for  a  person  that is consistent
 with  entries  for  other  persons  with similar characteristics.
 Thus,  a  person  who is reported as a 20-year  old  son  of  the
 householder but for  whom  marital  status  is  not  reported, is
 assigned  the  same  marital  status  as  that  of  the  last son
 processed in the same age group.  The allocation technique may be
 illustrated  by  the procedure used in the assignment for unknown
 age.  The process is carried out in the following steps:
     1.   The computer stores reported ages of persons by selected
          characteristics, including sex, relationship, marital
          status, and characteristics of other household members.
     2.   Each stored age is retained in the computer only until a
          person having the same set of characteristics and with
          age reported is processed through the computer in the
          edit operation. Then the age of this succeeding person
          is substituted for the age previously stored.
     3.   When a person processed  has  no  report  of age, or the
          entry is unacceptable, the age assigned to him or her is
          then stored for the last person who otherwise has the
          same set of characteristics.

 Substitution.  The editing  process also includes another type of
 correction,   namely   the  assignment   of   a   full   set   of
 characteristics for a person  or  a housing unit.  The assignment
 of the full set of housing characteristics  occurs  when there is
 no  housing  information  available.   If  the  housing  unit  is
 determined  to  be  occupied,  the  housing  characteristics  are
 assigned  from  the  previously processed occupied units.  If the
 housing unit is vacant,  the housing characteristics are assigned
 from the previously processed vacant unit.

 The assignment of a full set of characteristics for a person in a
 household  containing no information  for  all  or  most  of  the
 people, although persons were known to be present, is done in the
 following manner.   A  previously processed household is selected
 as a substitute and the full set of population characteristcs for
 each substituted person  is  duplicated.  These duplications fall
 into two classes: (1) "persons  substituted due to noninterview,"
 e.g., a housing unit indicated as  occupied but the occupants are
 not listed on the questionnaire, and (2) "persons substituted due
 to mechanical failure," e.g., where  the  questionnaire  page  on
 which persons are listed was not properly microfilmed.

 The   editing   process   ensures   that   the   distribution  of
 characteristics  for  persons and housing units assigned  by  the
 computer   corresponds   closely    to    the   distribution   of
 characteristics for persons and housing units  actually  reported
 in  the census.  Before the advent of the computer, this type  of
 process  was not feasible and the distrioution of characteristics
 to be used  for  assignment purposes was drawn from the preceding
 census or another source.

 Specific tolerances are established for the number of computer
 allocations and substitutions  that are permitted.  If the number
 of corrections is beyond tolerance,  the  questionnaires in which
 the errors occurred are clerically reviewed.  If it is found that
 the errors resulted from damaged questionnaires, from improper
 microfilming, from faulty reading by FOSDIC 1 / of undamaged
 questionnaires, or from other types of machine failure, the
 questionnaires are reprocessed.

 STF 1 includes four tables (56, 57, 58, 59) that allow users to
 determine the extent of allocation and substitution for a given
 geographic area.  For example, if a user wants to determine the
 extent of substitution in a particular county,  table 56 provides
 the  total number of substituted persons in creating  tabulations
 for that county.  Similarly, table 58 provides a count of housing
 units substituted.  In addition, tables 57 and 59 provide data on
 the extent  of allocation.  For example, a user interested in the
 number of persons  with  sex  or  marital  status allocated for a
 particular geographic area would want to know the value  in  the
 appropriate cells (3 and 7) of table 57.  Similarly, the 9 cells  of
 table 59 provide data on the number of housing units for which
 particular characteristics were allocated.

GLOSSARY

 Introduction

 Complete Count Concept Definitions

 The following definitions were taken from the 1980 Census  Users'
 Guide.   Since  the  items  described  here  are only those which
 appear in STF 1, there may be references to other terms which are
 not  defined  in  this  glossary.   A complete glossary  will  be
 available in the Users' Guide, scheduled  to  be  published later
 this year.

 Age-Black Population

 AGE.  Age at last birthday, i.e., number of completed years from
 birth to April 1, 1980, based on replies to a question  on  month
 and year of birth. This item was asked on a complete-count basis.

 Because  of  the  central importance of  the  data  on  age,  the
 question contains redundancies.   The age entry on the basic tape
 record is derived from the FOSDIC entries  of quarter and year of
 birth.  For those persons who do not provide this information but
 who do provide "age at last birthday," the census  enumerator  or
 clerk  uses  an  equivalency table to mark the appropriate FOSDIC
 circles.   The  item   "age   at  last  birthday"  is  used  only
 secondarily because of the tendency  of some people, in reporting
 their ages, to round off to "0" or "5" (and to report even rather
 than odd numbers).  The write-in entries  of  month  and  year of
 birth are requested because some people have difficulty with (and
 therefore skip) the FOSDIC marking system in this question.

 Age is tabulated by single years of age and by many different
 groupings,  such as five-year age groups.  Basic records identify
 single years (and quarter years on sample basic records) to 112.

     Median age. Calculated as the value which divides the age
     distribution into two equal parts, one-half of the cases falling
     below this value, one-half above. Median age is computed from the
     age intervals or groupings shown in the particular tabulation,
     and thus a median based on a less detailed distribution may
     differ slightly from a corresponding median for the same population
     population based on a more detailed distribution. If the median
     falls in the terminal category, e.g., 75 years and over, the
     median is shown asthe initial age of the category with a plus
     sign, e.g., 75+.

 Limitations:   In  previous   censuses,   undercoverage   of  the
 population   has   been   associated  with  age.   Young  adults,
 especially black males, were  missed  at a higher rate than other
 segments of the population.

 Historical comparability:  Age data have been collected in each
 census since 1790. Counts in 1970 for persons  100  years old and
 over were substantially overstated.

 see also:  AGE OF HOUSEHOLDER

 AGE OF HOUSEHOLDER. Derived from the age responses for the
 householders.  (See the definition of householder under Household
 Relationship).  Age and household relationship were determined on
 a complete-count basis.

 The most frequent applications of age of householder in 1980
 tabulations involve only two categories:  under 65 years old, and
 65  years  and  over.  More detailed categories appear among  the
 housing tabulations,  for example:  less than 25 years, 25 to 29,
 30 to 34, 35 to 44, 45  to  59,  60 to 64, and 65 years and over.
 Age  of  householder  is  also  derivable  from  age  tabulations
 cross-classified  by  household relationship  (STF  2).   Age  of
 householder is derivable from basic records in single years 15 to
 112.

 Historical comparability:  In  1970 and previous censuses, age of
 head was tabulated instead of age of householder (See Household
 Relationship).

 ALEUT POPULATION.  See RACE

 AMERICAN INDIAN POPULATION.  See RACE

 AMERICAN INDIAN RESERVATIONS/ALASKA  NATIVE  VILLAGES.   American
 Indian  reservations  are  areas  with boundaries established  by
 treaty,   statute,  and/or  executive  or   court   order.    The
 reservations  and their boundaries were identified for the Census
 Bureau  by  the  Bureau   of   Indian  Affairs  (BIA)  and  State
 governments.  Federal and State  reservations  are  located in 33
 States  and  may cross State, county, minor civil division/census
 county  division,   and  place  boundaries.  In  tabulations  for
 reservations,  tribal  trust  lands  outside  the  boundaries  of
 reservations (off-reservation)  are  not  included as part of the
 reservations (see below).

 Alaska  Native  villages are areas which were  specified  to  the
 Bureau by the State  of  Alaska which recognized them pursuant to
 the Alaska Native Claims Settlement Act, P.L. 92-203.

 Each American Indian reservation and Alaska Native village was
 assigned  a  unique 3-digit  code  by  the  Bureau.   Enumeration
 districts  (ED's)  and  block  groups  (BG's)  which  are  inside
 boundaries of  reservations  are designated with an "N" in the ED
 prefix field in tape files.

 Data summaries for American Indian reservations and Alaska Native
 villages are included in STF's  2B,  2C,  4B, and 4C, and reports
 PC80-1-B  and  -C,  and  HC80-1-A  and -B.  A population  subject
 report  (PC80-2 series) presenting additional  data  on  American
 Indian reservations  and  Alaska Native villages is also planned.
 Summaries on tape and in PC80-1-B and HC80-1-A show data not only
 for the reservation totals,  but  also  for parts of reservations
 that cross State or county boundaries.  Reservation data can also
 be  derived  from MARF, STF 1A, and STF 3A  by  the  addition  of
 component  ED  or   BG   summaries.  Maps  outlining  reservation
 boundaries will be included in the PC80-1-B and HC80-1-A reports.
 Reservation boundaries are also shown on Metropolitan Map Series,
 place, and  county maps.The locations of Alaska Native villages
 are also noted on all of these maps.

 Historical   comparability:   Data   on   115   American   Indian
 reservations  were  published in the 1970 census subject  report,
 American Indians, PC  (2)-1F.  However,  1980  data  may  not  be
 comparable  to  1970  information  because  of  boundary changes,
 improvements   in   geographic  identification,  new  enumeration
 techniques,  and other  procedural  changes  made  for  the  1980
 census.

 Data on Alaska Native villages are not available for previous
 censuses.  However, some cities and "unincorporated places" which
 were identified  in the 1970 census may correspond to 1980 Alaska
 Native villages.

 AMERICAN   INDIAN   SUBRESERVATION   AREAS.    Areas   known   as
 "districts," "agencies,"  "segments,"  "areas,"  or "communities"
 are  associated with some American Indian reservations  and  were
 identified  for  the  Census Bureau for the 1980 census by tribal
 governments or the Bureau  of  Indian  Affairs.   In a few cases,
 such subreservation areas extend beyond reservation boundaries or
 are  located  entirely outside the reservation.  American  Indian
 subreservations  recognized for the 1980 census are identified by
 a unique 3-digit code.

 Data for subreservations are not summarized in regular census
 tabulations; however, subreservation data can be derived by the
 addition of component  ED or BG summaries on MARF, STF 1A, or STF
 3A. ED's within a reservation  are  designated  by an "N" in that
 field.

 Historical  comparability:  American Indian subreservation  areas
 were not identified separately in previous censuses.

 AMERCAN INDIAN TRIBAL TRUST LANDS.  Some American Indian
 reservations  have tribal trust lands adjacent to the reservation
 which were identified  for  the  1980 census.  Tribal trust lands
 are  located outside the reservation  boundary  (off-reservation)
 and are associated with a specific reservation.

 Information for these areas is not summarized in regular census
 tabulations;  however,  each  area  has  been  assigned  a unique
 3-digit  code  which  appears in the reservation code field,  and
 summaries can be prepared  by  the addition of component ED's and
 BG's  from  MARF, STF 1A, or STF 3A.   Some  ED's  which  include
 tribal trust  lands  are  designated with an "A" in the ED prefix
 field in the data files. In  Oklahoma,  "A" prefix ED's designate
 the historic areas of Oklahoma (excluding  urbanized areas).  "A"
 prefixed  ED's  in all other States should be  disregarded.   For
 further information,  please write to Population Division, Racial
 Statistics Staff, Bureau of the Census, Washington, D.C.  20233.

 Historical comparability:  Tribal trust lands were not identified
 in previous censuses.

 Block-Block Group

 BLOCK.  Normally a rectangular piece of land, bounded by four
 streets.  However, a block  may  also  be  irregular  in shape or
 bounded  by railroad tracks, streams, or other features.   Blocks
 do not cross  the boundaries of counties, census tracts, or block
 numbering areas (BNA's).  They may cross place boundaries and the
 boundaries of minor  civil  divisions (MCD's).  When blocks cross
 place boundaries and, in 20 States (see figure 9, column 3), when
 they  cross MCD boundaries, separate  statistical  summaries  are
 presented for each part of the block.

 Census blocks are normally compact units, but there are important
 exceptions.   For example, in some suburbs, houses cluster around
 cul-de-sacs.  In  these  areas a census block may be fairly large
 since only those features  that  serve  as  the  perimeter  of an
 enclosed  area  are  treated as block boundaries.  Also, in those
 rural areas where they  are  numbered,  blocks  may  include many
 square  miles,  depending  on  the frequency of inter5ections  of
 roads, rivers, mountain ridges, or other physical features.

 Census data are tabulated by block  in all urbanized areas (UA's)
 and  generally  for  some  territory  extending   beyond  the  UA
 boundaries. Data will also be tabulated by block in  incorporated
 places with 10,000 or more inhabitants outside UA's, and in other
 areas which contracted with the Census Bureau for the  collection
 of block statistics.  Places outside of UA's are included  in the
 block  statistics  program  if  they  met  the  10,000 population
 criterion  in  the  1970  census,  in  official bureau  estimates
 through 1976, or in a special census taken  on or before December
 31,  1977.   Block  coverage  for  qualifying  places  is  within
 boundaries as of January 1, 1980. Five States contracted  for the
 preparation of block statistics for all of their territory,  both
 urban  and  rural,  not  already in the block statistics program.
 These States are Georgia,  Mississippi,  New  York, Rhode Island,
 and Virginia.

 A  block is identified by a 3-digit code which is  unique  within
 census  tract or, where tracts do not exist, BNA.  Since separate
 summaries  are provided for the parts of a block split by a place
 boundary or, in 20 States, an MCD boundary, tape users often will
 need to specify the place or MCD code, along with other codes, to
 retrieve data  for  a  block.   Blocks  are  defined  on detailed
 census-maps:  Metropolitan Map Series (MMS), Vicinity Map  Series
 (VMS),   place  maps,  and  county  maps.  The  extent  of  block
 statistics  coverage  is reflected on maps by the presence of the
 3-digit  block  number and  the  absence  of  ED  boundaries  and
 numbers.

 On census maps, when a block boundary ignores a minor physical
 feature, such as a railroad track, a "fishhook"( ) across the
 feature indicates  that  the black includes area on both sides of
 the feature.  Alternatively,  the  separate parts of such a block
 may have identical block numbers, each followed by an asterisk.

 1/See definitions for MCD's and blocks.
 2/The amount of data for MCD's and places is the same, for the States noted,
  in these reports: PC(1)-B and -C and HC(1)-A and -B.
 3/Subdivisions of Alaska's "census areas" or boroughs (county equivalents)
  are called "census subareas."  They take the place of MCD's or CCD's.

 The  maps  used for enumeration activities  were,  of  necessity,
 obtained several  years  prior to the census and therefore do not
 reflect recently constructed  streets.  Only those features shown
 on the maps can serve as block boundaries.

 Statistics were collected for approximately 2.6 million blocks in
 the 1980 census.  Block statistics  are included in PHC80-1 Block
 Statistics microfiche series in file  B  of  Summary  Tape File 1
 (STF 1B).

 Historical comparability: In 1970 block statistics were  prepared
 for  UA's  (and some territory beyond) located in SMSA's existing
 at the time of the census, as well as for contract areas.  Unlike
 1980, they were  not  prepared for places of 10,000 population or
 more outside UA's unless  done  under  contract,  nor for UA's in
 not-yet-defined SMSA's.

 Some blocks defined for 1970 will have new boundaries in 1980,
 primarily those on the edges of UA's and other areas of new
 development where the street patterns have changed.   To help the
 user  notice  a  change  wherever  a block has been redefined  by
 splitting  or  other  adjustment,  the  1970  block  number  will
 generally  not  be  reused  in  many areas, however,  many  block
 boundaries and numbers will be the  same  in  1980  as  in  1970,
 except  for  a  few  areas  where blocks were renumbered by local
 GBF/DIME-File  coordinating agencies  in  order  to  define  more
 desirable block groups.

 BLOCK GROUP (BG) A combination of census blocks that is a
 subdivision of a census tract or BNA and is defined in all areas
 where block statistics are collected.  (In areas where blocks are
 not identified, ED's are used.)

 BG's are not outlined on census maps, but are defined as that set
 of blocks sharing  the  same first digit within a census tract or
 BNA. For example, Block Group  "3"  within  a  particular  census
 tract would include any blocks numbered between 301 and 399.   In
 most  cases,  the numbering would generally involve substantially
 fewer than 50 blocks,  since  gaps  are  occasionally left in the
 numbering; e.g., block 12 might be followed by block 316.

 BG's are defined within census tract or BNA.  They may cross, and
 be split by, the boundaries of minor civil  divisions  (MCD's) or
 census county divisions (CCD's), places, congressional districts,
 urbanized  areas,  and  Indian  reservations.  When  this occurs,
 Statistical  Summaries  (data  records)  are  provided  for  each
 component or part.  To avoid mistaking a component Summary  for a
 complete BG summary, users should carefully study census maps  to
 note  any  BG's  split  by place, MCD or CCD, urbanized area, and
 Indian  reservation  boundaries.   Congressional   district  (CD)
 boundaries are not shown on census maps, So the maps  will not be
 of use in detecting BG's split by CD boundaries.

 BG  summaries  observe  boundaries  of some areas ( specifically,
 CCD's and, in 10 States, MCD's)which are ignored in summarizing data
 for the block statistics presentations in reports and on tape.  As a
 result, it will occasionally be necessary to add BG components
 together to match the sum of blocks in the same hundreds series.

 Statistics will be prepared for almost 200,000 BG's.  BG data,
 together with data for ED's, appear on STF's  1A  and  3A, and in
 any  corresponding  microfiche.  There are no published data  for
 BG's.

 Historical comparability:   In areas where BG's were tabulated in
 1970, many 1980 BG's will be the Same as their 1970 counterparts,
 with  exceptions  occurring  primarily   in   areas  where  tract
 boundaries  have  changed  or  where Substantial development  has
 taken place.  Also, BG parts, created  when BG's are split by the
 boundaries of higher level areas, will change  if such boundaries
 have changed.

 Many  areas  with  BG's  in  1980  had  ED's  in  1970, a  change
 occasioned  in  part  by  the  expansion  of the block statistics
 program,  and  in  part  because  ED's were used  for  tabulation
 purposes in 1970 instead of BG's in  Some  block  numbered areas.
 Where BG's have replaced ED's, there will be little comparability
 between 1970 ED's and 1980 BG's.

 Block Numbering Area-Children

 BLOCK NUMBERING AREA (BNA). An area defined for the purpose of
 grouping numbering blocks in block numbered areas where census
 tracts  have  not been defined typically, in non-SMSA  places  of
 10,000 or more  population and in contract block areas.  BNA's do
 not cross county  boundaries.   They  are  identified  by  census
 tract-type  numbers  ranging  from  9901.00  to 9989.99 which are
 unique within a county. While BNA numbers are  similar  to census
 tract  numbers,  BNA's are not census tracts and are not included
 in STF's 2 or 4.

 BNA's may be split by the boundaries of places, MCD's, and CCD's.
 Statistical  Summaries   appear  in  STF  1B  and  PHC80-1  Block
 Statistics microfiche series  for  the  component  parts of BNA's
 created when BNA's are split by the boundaries of places  and, in
 20  States,  MCD's.   (See  figure  9,  column 3.) Such component
 summaries appear in STF 1A and 3A when BNA's  are  split  by  the
 boundaries of MCD's in 10 other States and CCD's in the remaining
 20 States.

 Historical   comparability:  While   BNA's   were  also  used  in
 revious  censuses,  any  historical  comparability  is  generally
 coincidental.

 BOARDED-UP  STATUS.   Determined  for  vacant units intended  for
 year-round use.  Boarded-up units have windows  and doors covered
 by wood, metal, or similar materials to protect the  interior and
 prevent  entry.   A  single  unit  structure  or  a unit(s) in  a
 multi-unit Structure may be boarded-up in this way.

 Historical comparability:  This item is new for 1980.

 BOROUGH (IN ALASKA).  See COUNTY

 CENSUS AREA (IN ALASKA).  See COUNTY

 CENSUS  COUNTY  DIVISION (CCD).  A statistical subdivision  of  a
 county, roughly comparable  to  a  minor  civil  division  (MCD).
 CCD's are defined in 20 States (see figure 9, column 1) which  do
 not  have  MCD's  suitable for reporting census statistics (i.e.,
 the MCD's have either  lost their original significance, are very
 small in population, have  frequent boundary changes, and/or have
 indefinite boundaries). CCD's are established cooperatively by the
 Census Bureau and both State and local government authorities.
 They are generally defined by boundary features that seldom change
 and can be easily located, such as roads, rivers, and powerlines.
 located, such as roads,  rivers,  and  powerlines.


 CCD boundaries are represented on detailed census maps, such as place
 maps and county maps. In addition, CCD outlines appear at a small
 scale on maps published in several 1980 reports. CCD's, in alphabetic
 sequence,  are assigned unique, incremental 3-digit numeric codes
 within counties.

 Statistics for all CCD's appear in STF's 1A, 2B, 3A, and (under
 tentative plans) 4B, and in PC80-1-A and -B and HC80-1-A reports.

 Historical comparability: In 1980, CCD's are defined in one fewer
 State than in  1970-North Dakota returned to the use of its MCD's
 (townships). In the past, cities with 10,000 or more inhabitants
 generally were defined  as  separate  CCD's.   When  these cities
 annexed  territory, CCD boundaries also had to be adjusted.   For
 1980, many  of  these CCD boundaries were revised to conform with
 census  tract  boundaries   where  tracts  exist,  and  permanent
 physical features elsewhere, in an attempt to minimize future CCD
 boundary adjustments. Many CCD's which changed boundaries between
 1970 and 1980 are noted in footnotes  to  table 4 of the PC80-1-A
 reports for States with CCD's.

 CENSUS SUBAREA.  A statistical subdivision  of a "census area" or
 borough (county equivalent) in Alaska.  Census  subareas take the
 place of minor civil divisions (MCD's) or census county divisions
 (CCD's).

 Historical  comparability:   In  1970, Alaska county  equivalents
 were called "divisions," and some  were subdivided further.  Some
 of the census subareas used in the 1980  census  approximate  the
 1970 divisions or their subdivisions.

 CENSUS  TRACT.   A small statistical subdivision of a county.Tracts
 generally have stable boundaries. When census tracts are established,
 they are designed to be relatively homogeneous areas with respect to
 population characteristics, economic status, and living conditions.
 Tracts generally have between 2,500 and 8,000 residents. All standard
 metropolitan statistical areas (SMSA's) recognized before the 1980
 census are completely tracted. In addition, an estimated 3,000 census
 tracts have been established in 220 counties outside SMSA's. Five
 Five States are entirely tracted: Connecticut, Delaware, Hawaii,
 New Jersey, and Rhode Island. In all, there are over 43,300 census
 tracts for the 1980 census (including 465 in Puerto Rico).

 Census tract boundaries are established cooperatively by  local
 Census  Statistical  Areas  Committees  and  the Census Bureau in
 accordance with guidelines that impose limitations  on population
 size  and  specify  the  need for visible boundaries.  Geographic
 shape and areal size of racts are of relatively minor importance.
 Tract boundaries are established  with  the  intention  of  being
 mintained  over  a long time so that Statistical comparisons can
 be made from census to census. Census tracts observe county lines
 and are defined so  as  to cover all of the territory within each
 tracted county.  Within a  county,  tract boundaries may be split
 by other geographic boundaries.

 Census tracts are identified by a 4-digit basic code and may have
 a  2-digit  suffix,  e .g. , 6059.02. On  tape,  the  decimal  is
 implied. Many census tracts do not have a suffix.  In such cases,
 tapes give the 4-digit  code  followed  by  two  blanks.  Leading
 zeros  in  a tract number (e.g. , 0025.02) do not appear  on  the
 maps (e.g. , 25.02).

 Tract numbers  are always unique within a county, and, except for
 the New York SMSA,  are  also  unique  within an SMSA.  All valid
 census tract numbers are in the range 0001  to  9899.99; a number
 between 9901 and 9989.99 denotes a block numbering area (BNA).

 Census  tract boundaries are shown on all detailed  census  maps,
 such as place  maps  and  county maps.  In addition, census tract
 outline maps are being created  for  each  SMSA  and each tracted
 county outside SMSA's tract outline maps show only  those streets
 and physical features which serve as census tract boundaries.  In
 addition,  the boundaries of places, MCD's, CCD's, counties,  and
 States appear on tract outline maps.

 Census tract  data are presented in STF's 1A, 1B, 2A, 3A, and 4A,
 and in PHC80-2  Census  Tracts  reports.  In STF 1A and 3A, tract
 data are presented in hierarchical  sequence  within place within
 MCD or CCD. In a case where a tract is split by  place,  MCD,  or
 CCD  boundaries,  the  tape files will have summaries for each of
 its parts.  To get data for the whole tract, it will be necessary
 to add up the components.   In  STF  lB  the situation is similar
 except that MCD boundaries are observed in  only  20 States. (See
 figure 9, column 3)  MCD boundaries in the other 10  States  with
 MCD's  and CCD boundaries in the remaining 20 States are ignored.
 In the major  summaries for census tracts--those in STF 2A and 4A
 and in PHC80-2  Census Tracts series--tract summaries observe the
 boundaries of places  of  10,000  or  more  population.  Separate
 summaries provide totals for split tracts.

 Historical   comparability:  Census tracts are  defined  with  an
 overall goal of census-to-census comparability.  Some 1970 tracts
 have been subdivided due to increased  population,  but  the  new
 tracts  can  be  recombined  by the user for comparison with 1970
 tracts.  This affects about 8  percent of all 1970 tracts.  Other
 changes have included combinations  of  two  or  more  small 1970
 tracts  (less  than 1 percent of all 1970 tracts) and adjustments
 to tract boundaries  where old boundary features have disappeared
 or better boundaries (e.g., freeways) have come into being.  In a
 few areas, local Census Statistical Areas Committees undertook
 extensive redefinition of census tracts.

 Both  the  number of tracted  counties  and  the number of census
 tracts increased by over 20 percent between 1970  and  1980.  The
 reporting  of  data for split tracts has also increased.  Whereas
 1970 Census Tracts reports gave data for tract parts created when
 tracts were split  by  the  boundaries  of only those places with
 25,000  or  more population, 1980 reports observe  boundaries  of
 places as small  as   10,000, 1980 STF's 2 and 4 present data for
 the components of split  tracts,  as  well  as  for whole tracts,
 whereas   their   1970  counterparts  did  not  provide  separate
 summaries for the components of split tracts.

 CENTRAL BUSINESS DISTRICT  (CBD).   An  area  of  very  high land
 valuation   characterized  by  a  high  concentration  of  retail
 businesses, service  businesses,  offices,  theaters, and hotels,
 and  by  a  high  traffic  flow,  A  CBD  follows  census   tract
 boundaries, i.e., it consists of one or more whole census tracts.
 CBD's  are  identified only in central cities of SMSA's and other
 cities with a population of 50,000 or more, and are designated by
 local Census  Statistical  Areas  Committees in consultation with
 the Census Bureau.  However, some eligible cities have chosen not
 to  participate in the CBD delineation  program.   CBD's  do  not
 extend beyond the boundaries of the city.

 The CBD's now recognized were delineated for the 1977 Economic
 Censuses.   The  Bureau  does not plan to prepare 1980 statistics
 for CBD's, but users may derive  data  by  aggregating  data  for
 component census tracts or smaller areas.  Records for such areas
 in  the  Geographic  Identification Code scheme and on 1980 files
 include a CBD code when the area is in a CBD.

 Historical comparability:  At  the time of the 1970 census, CBD's
 were defined only in cites of 100,000 or more persons.

 Condominium Status-Family

 CONDOMINIUM  STATUS. A type of ownership of an apartment in a building-
 or a house in a development--where ownership of common areas is shared.

      Condominium.  Ownership in which the owner has an individual deed
      (and likely also an individual mortgage) on the unit, and also
      holds a common or joint ownership in all common areas, such as
      grounds, lobbies, and elevators.  A condominium unit need not be
      occupied by the owner to be counted.

      Noncondominium.  All other types of ownership, including
      cooperatives where a share in a corporation with title to a
      multi-unit property entitles the owner to occupy a specific unit.

 Limitations:  In test survey taken before the census, an
 overstatement of condominiums was noted.

 Historical comparability:   In  1970,  Owner-occupied cooperative
 and condominium  units  were  identified together. In 1980,  only
 condominium units are identified, since  cooperative  units  were
 extensively  misreported  in test surveys before the census.  The
 1980 item also includes vacant  and  renter-occupied  units,  not
 just owner-occupied units as in 1970.

 CONGRESSIONAL DISTRICT. One of 435 State or sub-state areas from
 which persons are elected to the U.S.  House of Representatives.
 congressional districts observed for the 1980 census are those as
 designated  for  the  96th Congress; this designation has been in
 effect since the 94th Congress  (1975-1976),  with  one  boundary
 change  in  Tennessee  which  took effect with the 95th Congress.
 congressional districts for the 98th Congress (1983-1984) will be
 defined  by  the  States  after  1980  population  counts  become
 available.

 Small-scale maps of congressional districts appear in the
 Congressional District Data Book and the congressional District
 Atlas.  Congressional district boundaries are not shown on 1980
 census map series.

 Historical comparability: 1970  census  data  are  available  for
 Congressional Districts as defined for the 94th - 97th Congresses
 in the Congressional District Data BOOK, except for the Tennessee
 change noted above.

 COUNTY.  The primary political and  administrative subdivision of
 a State. In Louisiana, such divisions are called parishes.  In
 Alaska  23  boroughs  and  "census  areas"  are treated as county
 equivalents  for  census  purpose.  Several  cities   (Baltimore,
 Maryland;  St.Louis,  Missouri;  Carson  City,  Nevada;  and   41
 Virginia  cities) are independent of any county organization, and
 thereby constitute  primary  divisions  of  their  States and are
 treated the same as counties in census tabulations.

 County  boundaries  are  shown  on  most census maps.  A  3-digit
 Federal  Information  Processing  Standards  (FIPS)  county  code
 identifies  each  county  uniquely within  State.   Counties  are
 numbered in alphabetic sequence, with independent cities numbered
 separately at the end of the list.

 There are 3,137 counties and  county  equivalents  recognized for
 the 1980 census.  Tabulations for all counties appear  in STF's 1
 through  4,  and  in  PC80-1-A,  B, and -C; HC80-1-A and -B;  and
 PHC80-3 reports. Tabulations for large  counties (population size
 cutoff to be determined) appear in STF 5.

 Historical comprability:  A number of changes have occurred to
 county boundaries since 1970.  A new set of county equivalents
 (boroughs and census areas) has been defined  for  Alaska, and in
 some cases these county equivalents differ considerably from the cen-
 sus divisions  recognized  for  1970.   In  addition, there are minor
 changes in counties for South Dakota and  Hawaii.   In  Virginia,
 county boundaries have changed as a result of the creation of new
 independent  cities  and  annexations by independent cities  most
 other  changes  represent minor  adjustments  of  the  boundaries
 between  counties.    Those  counties  which  changed  boundaries
 between 1970 and 1980 are  noted in footnotes at the end of table
 4 of the PC80-1-A report for each State.

 COUNTY EQUIVALENT.  See COUNTY

 COUNTY SUBDIVISION:  See CENSUS COUNTY DIVISION; CENSUS SUBAREA;
                      MINOR CIVIL DIVISION

 DIVISION.  (CENSUS GRAPHIC).  A census geographic division is one
 of the nine groups of States  which  are subdivisions of the four
 census geographic regions of the United States.  (See figure 10.)
 Census  geographic divisions are identified  by  a  1-digit  code
 which is  also  the  first digit of the 2-digit census geographic
 code for each State in the division.

 Historical  comparabilily:   Census   divisions   have   remained
 unchanged since the 1910 census, except for the expansion  of the
 Pacific Division to include Alaska and Hawaii.

 ECONOMIC  SUBREGION  (ESR).  A  grouping  of State Economic Areas
 (SEA's) which brings together those SEA's which  are most closely
 related  in  terms  of their economic and social characteristics.
 The  areas were first  defined  following  the  1950  census  and
 updated  after  the  1960  census.   In  order  to  achieve  such
 homogeneity,  State  boundaries  refrequently  crossed.   The 510
 SEA's  are  grouped  into  121  ESR's.   A  digit numeric code is
 assigned  to each ESR.  No data summaries will  be  prepared  for
 ESR's, although the ESR code appears on the geographic records of
 the summary tape files.

 Historical comparability:  ESR boundaries have remained the same
 since 1960.

 ELECTION  PRECINCT.   In  census usage, any of a variety of types
 of  areas  (e.g.,  election  districts,   precincts,  legislative
 districts,  wards)  defined by States and local  governments  for
 purposes of elections.   Under  a cooperative Census Bureau/State
 program, the boundaries of election  precincts and ED's or census
 blocks were drawn 50 as to be compatible in many States.

 The Bureau prepared election precinct data for all or portions of
 23 States; in some other States, users  may  aggregate block data
 to  create  election precinct statistics.  The election  precinct
 data appear in  the  P.L.  94-171 Population Counts tape file and
 on microfiche of that file.

 Historical comparabilily:  Election precincts have not been
 recognized in past censuses,  except  where  they  have served as
 minor civil division boundaries.

 ENUMERATION DISTRICT (ED).  An area used in the 1980  census  for
 data  collection activities and as a tabulation area where blocks
 are not  present.   ED's  do not cross the boundaries of legal or
 statistical  areas;  for  example,  census  tracts,  MCD's/CCD's,
 places, counties, congressional  districts,  and States.  Because
 of  these  constraints,  they  vary  widely  in population  size,
 although they do not generally exceed a population  of  1,600  in
 areas  where  the  census  was  taken by mail, or a population of
 1,000  in  areas  where  the  census was  taken  by  conventional
 enumerator canvassing.  The population  limits  are  designed  so
 that  an  ED  generally  represents a reasonable workload for one
 enumerator.  About 1,000 jurisdictions  in 47 States participated
 in  a  program for local definition of ED's.   In  areas  without
 blocks,  ED's are the smallest unit of census geography for which
 statistics are prepared.

 ED boundaries  are  shown  on  MMS/VMS, place, and county maps in
 areas where there are no block numbers.  ED's are identified by a
 4-digit number (except that leading  zeros, when they occur in ED
 numbers,  do  not  appear on the maps).   An  ED  number  may  be
 followed by a one-letter  alphabetic  suffix.  The suffix is used
 to identify subdivisions of ED's made during  data collection and
 processing  activities  where the original ED proved  to  be  too
 populous for an efficient work unit, or to accommodate a revision
 to  a place or other boundary  made  after  January  1,  1978  in
 mailout/mailback  areas or January 1, 1979 in conventional census
 areas.  An ED number may also have a one-letter prefix indicating
 that  the ED is of a  special  type  (e.g.,  an  American  Indian
 reservation),   but  the  prefix  is  not  necessary  for  unique
 identification of  the  ED.   ED  numbers  do not repeat within a
 county.  Any ED may be uniquely identified by accompanying its ED
 code with the 2-digit State code and 3-digit county code.

 Statistics will be prepared for about 100,000 ED's.  ED data,
 together with data for BG's, appear on STF's 1A and 3A and
 corresponding microfiche.  In addition, ED data  appear on STF 1B
 to complement the summaries for blocks.  There are  no  published
 data for ED's.

 Historical comparability:  Many areas which were covered  by ED's
 in 1970 are summarized in terms of blocks and BG's for 1980.   In
 some cases it may be possible to add up blocks to approximate the
 1970 ED's, based on detailed comparison of 1980 and 1970 maps.

 In areas covered by ED's for 1980, enumeration considerations
 dictated  ED  size  and design, and historical comparability does
 not normally enter into consideration.

 ESKIMO POPULATION.  See RACE

 EXTENDED CITY.  See URBANIZED AREA

 FAMILY.  Two or more  persons, including the householder, who are
 related by birth, marriage,  or adoption and who live together as
 one household; all such persons  are considered as members of one
 family.

 (Persons not in families and not inmates of institutions are
 classified as unrelated individuals.)  Families are defined using
 responses to the complete-count household relationship question.

 If the son/daughter of the person or couple who maintains the
 household and the son's or daughter's spouse  and/or children are
 members of the household, they are treated as part of the
 householder's  family.  A roomer/boarder and his/her  spouse  who
 are not related  to  the  person  or  persons  who  maintain  the
 household,  or  a resident employee and his/her spouse living in,
 are not counted as  a family, but as individuals unrelated to the
 householder.  Thus, a  household  can contain only one family for
 purposes of census tabulations.

 A person maintaining a household alone, or with unrelated persons
 only, is regarded as a household but not as a family.  Thus, some
 households do not contain a family.

 (In certain Census Bureau surveys, families as defined here are
 referred to as "primary families." The term "secondary family"
 refers to a resident family unrelated to the householder, such as
 a roomer and his/her spouse.  Tabulations  of  families from such
 surveys include secondary families.)

 Historical  comparability:  The  1970 definition for  family  was
 similar to that used in 1980. In 1960,  secondary  families  were
 separately identified.

 Family Type-Households, Persons In

 FAMILY TYPE.  Families are classified by type according to sex of
 the householder and the presence of relatives, based on questions
 on  sex  and  household  relationship  asked  on a complete-count
 basis.

     Married-couple family. A family in which the householder and
     his/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. Family with a
          female householder and no spouse of householder present.

 Historical comparability:  The terminology for the family-type
 categories  is  new  for  1980.  The  categories  are  reasonably
 compatible  with  the  1970  categories, "husband-wife families,"
 "families with other male head," and "families with female head."

 See also:  FAMILY; HOUSEHOLD TYPE

 GROUP QUARTERS, PERSONS IN.  Persons in living arrangements, such
 as nursing homes or rooming houses,  which  are  not  households.
 Group quarters status was determined on a complete-count basis.

 Two general categories of persons in group quarters are recognized.

     Inmate of institution.  A person under care or custody at the
     time of enumeration. Inmates are persons in such facilities as
     homes, correctional schools, specialized hospitals, or wards
     for juveniles or the physically or mentally handicapped; persons
     in homes or hospitals for chronicdiseases; persons in homes for
     unmarried mothers or in nursing (convalescent and rest) homes;
     persons in homes for the aged and dependent; and persons in
     correctional institutions. These persons are enumerated as
     residents of an institution--regardless of their length of stay
     in the particular place. Some tabulations include data by major
     types of institutions (home for the aged, mental hospital,
     correctional institution, and other institutions).

     Other persons in group quarters. A person living in
     noninstitutional group quarters.  Noninstitutional groupquarters
     have nine  or  more persons unrelated to the person in column 1
     of the questionnaire, or ten or more unrelated persons, and
     include such living quarters as rooming and boarding houses,
     communes, workers' dormitories, and convents or monasteries.

     Persons residing in certain other types of living arrangements
     are classified as living in noninstitutional group quarters,
     regardless of the number or relationship of people in the unit.
     These include persons residing in military barracks, on ships,
     in college dormitories or in sorority and fraternity houses;
     patients in  short-term medical, maternity and, surgical wards
     of hospitals who  have no usual home elsewhere; live-in staff
     members of institutions and other group quarters, provided that
     their living arrangements do not meet the housing unit definition;
     and persons staying in missions, flophouses, Salvation Army
     shelters, railroad stations, etc.

 Historical comparability:  In 1970, the "other person in group
 quarters"  was  defined  as a person in noninstitutional quarters
 with five or more persons unrelated to the head (rather than nine
 or more unrelated to the householder  in  1980)  or  six  or more
 unrelated persons altogether (as compared to ten or more in 198O)

 HISTORIC  AREAS  OF  OKLAHOMA  (EXCLUDING  URBANIZED AREAS).  The
 historic  areas  of  Oklahoma consist of the former  reservations
 which  had  legally  established  boundaries  during  the  period
 1900-1907. These reservations  were  dissolved during the two- to
 three-year period preceding the statehood  of  Oklahoma  in 1907.
 The  former reservation boundaries are used for planning purposes
 by tribes  and the Federal government.  In the census, the entire
 area encompassing  the former reservations was identified (except
 for parts inside urbanized  areas  as approximated in preparation
 for the 1980 census).  Individual former  reservations  were  not
 identified separately.

 Information for the historic areas is not summarized in regular
 census tabulations; however, some information will be included in
 special  reports  or  unpublished  tabulations.   Also, since the
 historic  areas  have been assigned a unique 3-digit  code  which
 appears in the reservation  code  field  of  each component area,
 summaries can be prepared by the addtion of component  ED's  and
 BG's  from  MARF,  STF1A,  or  STF  3A.  Also, the historic areas
 (excluding   urbanized   areas)   are  distinguished   from   the
 reservation in Oklahoma by an "A" in  the  ED  prefix field.  The
 boundaries  for  "A"  ED's  are drawn to follow visible  features
 which approximate the Oklahoma historic land boundaries.

 Historical comparability:  Historic areas of Oklahoma were not
 identified in previous censuses.

 HOMEOWNER VACANCY RATE.  The number of year-round vacant units
 "for sale only" as a percent of the total homeowner inventory,
 i.e., all owner-occupied  units  and  all year-round vacant units
 for sale only.

 See also:  VACANCY STATUS

 HOUSEHOLD.   The  person  or persons occupying  a  housing  unit.
 Counts of households, householders,  and  occupied-housing  units
 are  always  identical  in complete-count tabulations.  In sample
 tables,  the  numbers may not  always  be  the  same  because  of
 differences in weighting sample data.

 See also:  HOUSEHOLD RELATIONSHIP; HOUSEHOLD TYPE; HOUSING UNIT

 HOUSEHOLD,  PERSONS  IN.   The  number  of  persons living in the
 housing unit.  All occupants are counted--not  just those related
 to  the  householder,  but  also any lodgers, roomers,  boarders,
 partners,  wards, foster children,  and  resident  employees  who
 share the living quarters.

 Figures for "persons in households" match those for "persons in
 units" in tabulations based on complete-count data.  In sample
 tabulations,  they  may  differ because of the weighting process.
 The  phrase  "persons  in  household"   is  used  for  population
 tabulations,  persons  in  unit" for housing  items.  "one-person
 households" and "persons living alone" are synonymous.

 Household Relationship-Inmate of Institution

 HOUSEHOLD RELATIONSHIP.  Relationship  to  the person in column 1
 of  the  census  questionnaire,  ascertained from  replies  to  a
 complete-count question.

     In household. Persons in the household include:

           Householder.  The person who was reported in column 1 on the
           questionnaire. This was to be the person or one of the
           persons in whose name the home was owned or rented.  If
           there was no such person, any adult household member at
           least 15 years old who was not a roomer, boarder, or paid
           employee was to be reported in column 1.  In complete-count
           tabulations, the number of householders is the same as the
           number of households or occupied housing units.  In sample
           tabulations, the numbers may not always be the same because
           of differences in weighting sample data.

               Family householder. A householder living with one or more
               persons related to him or her by birth, marriage, or
               adoption.

               Nonfamily householder. A householder living alone or only
               with persons not related to him or her.

           Spouse. For most tabulations, "spouse" is defined as the
           husband or wife of the householder, living with the
           householder. This category may include persons in common-
           law marriages as well as persons in formal marriages; it
           does not include a partner or roommate of the opposite sex.
           In complete-count tabulations, the number of spouses is the
           same as the number of married-couple families or married-
           couple family households.  The number of Spouses, however,
           is generally less than half of the number of "married
           persons with spouse present" in sample tabulations, since
           only spouses of householders are Specifcally identified as
           "spouse."  Sample tabulations of the number of married
           persons with spouse present include subfamilies--see the
           definition of subfamily under Family--as well as married-
           couple families.

 Child.  A son, daughter, 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.

     Own child.  A never-married child under 18 years who is a son,
     daughter, stepchild, or 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.

 Related child.  An "own child" or any other family member
 (regardless of marital status) who is under 18 years,  except the
 householder or spouse.  Foster children are not included since
 they are not related to the householder.

 Other relative.  A household member related to the householder by
 blood, marriage, or adoption, but not included specifically in
 another relationship category.  The scope of this category may
 differ from table to table, depending on what other relationship
 categories are included.  In detailed tabulations (STF 2,  STF 5,
 or PC80-1-D) the following categories may also be shown:

      Parent. In complete-count tabulations, the father or mother
      of the householder, including a stepparent or adoptive
      parent.  On sample basic records and microdata files,
      fathers- and mothers-in-law constitute a separate category
      coded from write-in responses under "other relative" on the
      questionnaire one STF 5 and PC80-1-D tabulation includes
      both parents and parents-in-law in the same category.

      Brother or sister.  In complete-count tabulations, the
      brother or sister of the householder, including
      stepbrothers, stepsisters, and brothers and sisters by
      adoption.  On sample basic records and microdata files,
      brothers- and sisters-in-law constitute a separate category
      coded from write-in responses, One STF 5 and PC80-1-D
      tabulation  includes brothers- and sisters-in-law along with
      brothers and sisters in the same category.

      Son- or daughter-in-law. Spouse of a son or daughter of the
      householder, coded from write-in responses.

      Grandchild.  Grandchild of the householder, coded from
      write-in responses.

      Other.  The following categories are separately coded in
      sample basic records and microdata files only: nephew/niece,
      grandparent, uncle/aunt, cousin, and "other."

 Nonrelative.  Any household member, including foster children,
 not related to the householder by birth, marriage, or adoption.
 The following categories are presented in certain more detailed
 tabulations.

      Partner or Roommate.  Nonrelative who lives together and
      shares expenses with the householder.

      Roomer or boarder, Roomer, boarder, lodger, or relative of
      such; foster child or ward of the householder.

      Paid employee. Nonrelative who is paid to provide household
      services, such as a maid, housekeeper or gardener.

      Other nonrelative.  Nonrelative  who  cannot be described by
      above categories, including a person who is related to a
      partner or roommate or to a paid employee.

 Inmate of institution and other person in group quarters.
 (Treated as categories of household relationship for purposes of
 tabulation.  For definitions, see Group Quarters, Persons In.)
 Persons in group quarters are excluded from  counts of persons in
 households.

 Responses to the household relationship item were also used in
 defining families ( see Family; Family Type; Household Type)
 Tabulations frequently report relationship for  persons in family
 households separately from persons in nonfamily households.

 Historical comparabilty:  The question was revised from 1970 to
 replace the "head of household" category with a format using a
 reference person, i.e., the "person in column 1." The 1980
 householders differ from 1970 household heads primarily where the
 wife  in  a  married  couple family is listed as the  "person  in
 column 1." In 1970, the  husband always was designated the "head"
 of such a family.  In 1980  tabulations,  the substitution of one
 spouse for the other as the reference person  may  affect certain
 of the classifications, such as "parent" or "brother  or sister,"
 within  the "other relative" grouping.  The person in whose  name
 the house  or  apartment  is  owned  or rented may in a few cases
 differ from the person considered by other  household  members as
 the  "head,"  but  this  is  expected  to  affect  relatively few
 households.

 The  1970  questionnaire  category  "other relative of head"  was
 replaced by three categories, "brother/sister,"  "father/mother,"
 and  other relative." Since the category "patient or  inmate"  is
 marked  only by census enumerators, it was moved to the bottom of
 the  form  in  a  space  reserved  "for  census  use  only."  New
 nonrelative  categories  include  "partner,  roommate"  and "paid
 employee."  the  former  question asking relationship to head  of
 family or household was asked from 1880 to 1970.

            HOUSEHOLD TYPE

 HOUSEHOLD TYPE.  Households  are  classified by type according to
 sex of the householder and the presence  of  relatives,  based on
 questions asked on sex and household relationship.

 This item was determined on a complete-count basis.

     Family household.  A household including a family. (See Family.)
     A family household may also include nonrelatives living with the
     family.  The following subcategories are frequently provided:
     married couple family; family with male householder, no wife
     present; and  family with female householder, no husband present.
     (See Family Type.)

     Nonfamily household A household consistng of a person livng
     alone or of a householder  living with persons not related to
     him or her.

 Historical  comparability:  In 1970,  nonfamily  households  were
 termed primary  individual households; a primary individual being
 a person living alone  or  the  head  of  a household in which no
 relatives of the head were present.

 See also:  FAMILY; FAMILY TYPE; UNRELATED INDIVIDUAL

 HOUSING UNIT.  A house, apartment, mobile home  or trailer, group
 of rooms, or single room occupied or intended for occupancy as a
 separate living quarters. Separate living quarters are those in
 which the occupants do not live and eat with any  other person in
 the  structure and which have direct access from the  outside  of
 the building or through a common hall.

 The occupants  of  a  housing  unit  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 (except  as  described in the definition for Persons
 In  Group  Quarters). For vacant  units,  enumerators  apply  the
 criteria of  Separateness  and direct access wherever possible to
 the likely use by intended occupants,  or otherwise to the use by
 previous occupants. Both occupied and vacant  housing  units  are
 included  in  the  housing  inventory,  except  that recrational
 vehicles, tents, caves, boats, railroad cars, and  the  like  are
 included only if they are occupied.

 Historical  comparabiliy:  The  first  Census  of Housing in 1940
 established  "dwelling unit" concept.  Although  the  term became
 "housing  unit" and the definition has been modified slightly  in
 each  succeeding  census,  the  1980  definition  is  essentially
 comparability  to previous censuses, In 1970, the definition of a
 housing unit stipulated that the occupants live and eat sparately
 and have either direct access or complete kitchen facilities, For
 1980, direct access  is  required;  the  alternative  of complete
 kitchen  facilities  has  been dropped, Excluded in 1970,  vacant
 mobile  homes  are included in  the  1980  housing  inventory  if
 intended for occupancy where they stand, Also in 1970, units with
 six or more unrelated  persons living together were classified as
 group quarters; for 1980  that  requirement  was raised to ten or
 more unrelated persons.

 Marital Status-Parish

 MARITAL STATUS. All persons were asked whether they were "now
 married." " widowed,"  "divorced," "separated," or "never married."
 Marital status data are  tabulated  only for persons 15 years old
 and over, This item was asked on a complete-count basis.

 Couples  who  live  together  (unmarried   persons,   persons  in
 common-law  marriages,  etc.) were allowed to report the  marital
 status they considered the most appropriate.

      Single. All persons who have never been married, including
      persons whose only marriage was annulled.

      Ever married. Persons married at the time of enumeraton,
      including those sparated, plus widowed or divorced persons.

      Married, except separated.  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 approp-
      riate. In certain tabulations based on sample data, married
      persons are further classified as "married, spouse present"
      or  "married, spouse absent." See below.

      Separated.  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.  Separated includes persons with a limited divorce.

      Widowed.  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:

    Married. Includes persons categorized as separated above.

       Married, spouse  present.  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.

       Married, no spouse-present.  Married  persons whose wife or
       husband was not enumerated as a member of the same household,
       and all married persons living in group quarters.

           Separated.  Defined above.

           Other married, spouse absent.  Married persons whose spouse
           was not enumerated as a member of the same household, exclu-
           ding separated. Included are those whose spouse was employed
           and living away from home, absent in the Armed Forces, or an
           institution.

 Differences between the number of married males and the number of
 married females arise  from the fact that some husbands and wives
 have their usual residences in different areas, and, in sample
 tabulations, from different weights applied to the data.  Any
 differences between "married,  spouse  present" males and females
 are  due  solely to sample weighting; by definition  the  numbers
 should be the same.

 Historical  comparability:  For 1980, marital status is tabulated
 for persons 15  years  old  and  over,  a  change from the period
 1950-1970 when marital status was tabulated  for persons 14 years
 old and over. A marital status question has been  asked  in every
 census since 1880.

 MINOR   CIVIL   DIVISION   (MCD).   A   primary   political   and
 administrative   subdivision   of   a  county.   MCD's  are  most
 frequently known as townships, but in  some  States  they include
 towns, magisterial districts, and similar areas.  A few  counties
 have  some  territory not organized into MCD's; such "unorganized
 territory" is treated as one or more MCD's for census purposes

 MCD's are used  for  census  purposes in 29 States (see figure 9,
 column 2). In 20 of the remaining  States, CCD's are used in lieu
 of MCD's, and in Alaska, census subareas are used.

 The Census Bureau has assigned each MCD, alphabetically Sequenced
 within county, an incremental, unique 3-digit numeric code.  In
 addition, MCD's in 11 States have a 4-digit "MCD sequence number"
 which allows MCD's to be sorted into alphabetical sequence within
 a State.

 MCD boundaries are represented on all detailed census maps. In
 addition, MCD outlines appear on small-scale  maps  published  in
 PC80-1-A  and HC80-1A reports and in conjunction with the PHC80-2
 series. There  are  more  than  26,000 MCD's defined for the 1980
 census.

 Statistics for all MCD's appear in  STF's  1A, 2B, 3A, and (under
 tentative  plans)  4B,  and  in  PC80-1-A  and -B,  and  HC80-1-A
 reports. In 20 States (specified in column 3  of  figure 9), most
 MCD's Serve as functioning general-purpose governments, and these
 active  MCD's  are  included  in  PHC  80-3 Summary Stistics  for
 Governmental Units.  All MCD's in block  numbered  areas of these
 States are included in PHC80-1 Block Statistics microfiche series
 and STF 1B.  Finally, in 11 States (all 9 States in the Northeast
 region, plus Michigan and Wisconsin), MCD data are published in a
 manner parallel to that of places of the same population  size in
 tables  of PC80-1-B and -C, and HC80-1-A and -B.  (See figure  9,
 column 4.)

 Historical  comparability:   CCD's  were  used in North Dakota in
 1970,  but  for  1980  that  State  returned to the  use  of  its
 townships.   A  number  of  MCD's in other  States  have  changed
 boundaries.  Changes have resulted  from  municipal  annexations,
 mergers  or  dissolutions of MCD's, and other causes.  There  are
 seven States where  MCD  boundaries  have  changed substantially:
 Arkansas, Louisiana, Maryland, Mississippi,  Nebraska,  Virginia,
 and  West  Virginia.   MCD's  which are changed boundaries during
 1970  to  1980 are noted in footnotes  to  table  4  of  PC80-1-A
 reports for States with MCD's.

 MUNICIPIO.  See PUERTO RICO

 NEIGHBORHOOD. For purposes of the Census Bureau's Neighborhood
 Statistics  Program,  a neighborhood is a locally-defined subarea
 of a locality. Neighborhoods must have official recognition,

 nonoverlapping  boundaries,   and   a   mechanism  through  which
 neighborhood  residents  may  present their  views  on  municipal
 matters.

 Historical comparability:  Such neighborhoods have not been
 recognized in past censuses.

 NONRELATIVE.  See HOUSEHOLD RELATIONSHIP

 OCCUPANCY STATUS. The classification  of  all  housing  units  as
 either occupied or vacant.

      Occupied.  The classification of a housing unit with a person
      or persons living in it as a usual residence when enumerated--
      or only temporarily absent, for example, on vacation. A house-
      hold consists of all the persons who occupy a housing unit.
      Therefore, counts of households and occupied housing units
      should match--although complete counts may differ slightly
      from sample data.

      Vacant.  The classification of a housing unit with no one
      living in it at the time of enumeration, unless its occupants
      are only temporarily absent. If, at the time of enumeration,
      the unit is temporarily occupied entirely be persons who have
      a usual residence elsewhere, it is also classified as vacant.

 Historical comparability:  Similar data have been collected since
 1940.

 Persons Per Room-Puerto Rico

 PERSONS PER ROOM. A derived  measure  obtained  by  dividing  the
 number  of persons in each occupied housing unit by the number of
 rooms in  the  unit.  The  figures shown refer, therefore, to the
 number of housing units having the specified ratio of persons per
 room.  For example, the number of units with 1.01 or more persons
 per room is the number of units  occupied  by  more  persons than
 there are separate rooms.

 See also:  ROOMS

 PLACE.  A concentration of population which may or may not have
 legally  prescribed  limits, powers, or functions.  Most  of  the
 places identified in the  1980 census are incorporated as cities,
 towns, villages, or boroughs.   In  addition,  census  designated
 places  (called "unincorporated places" in earlier censuses)  are
 delineated for 1980 census tabulations. There are about 23,000
 places recorded in the 1980 census. Places do not cross State
 boundaries.

      Incorporated place.  A political unit incorporated as a city,
      borough (excluding Alaska and New York), village, or town
      (excluding the New England States, New York, and Wisconsin).
      In most States, incorporated places are subdivisions of the
      MCD or CCD in which they are located; for  example, a village
      located within and legally part of a township. In some states,
      incorporated  places  are  independent  of surrounding town-
      ships  or towns and therefore  are  also  treated  as  MCD's.
      In a few States, the pattern is mixed. Almost 4,000 incorporated
      places cross MCD/CCD and/or county boundaries.

      There are about 20,000 incorporated places  recognized in the
      1980 census.

      Census  designated place (CDP).  A densely settled population
      center without legally defined corporate limits  or corporate
      powers or functions. Each CDP has a definite residential
      nucleus  with  a  dense,  city-type  street  pattern, and ideally
      should  have  an  overall  population density of at  least  1,000
      persons per square mile.  In  addition,  a  CDP  is  a  community
      that  can  be  identified  locally by place name.  Boundaries  of
      CDP's  are  drawn  by  the Census  Bureau,  in  cooperation  with
      State  and  local agencies,  to  include,  insofar  as  possible,
      all  the  closely    settled   area.    In   the   1980   census,
      statistics  are  tabulated  for  each  CDP with 5,000 inhabitants
      or  more  if located in an urbanized area  (UA)  with  a  central
      city of 50,000  or  more  and  for  each CDP of 1,000 inhabitants
      or  more  if  in a UA with no central city  of  50,000  or  more.
      Some  CDP's--notably   in  the  Northeast--coincide  with  MCD's.
      On STF's these are treated  as  both  places  and  MCD's,  but in
      printed  reports  they  are  shown  only  in  MCD tables to avoid
      duplication.   Outside  of UA's, statistics are tabulated  in  48
      States  for CDP's of 1,000  or  more,  in  Hawaii  for  CDP's  of
      300 or more, and in Alaska for CDP's of 25 or more.

      There are approximately 3,000 CDP's recognized in the 1980
      census.

 Incorporated place and CDP boundaries are shown on all detailed
 census maps.   For  tracted  areas,  boundaries of all places are
 shown on census tract outline maps.  County  subdivision maps, at
 still smaller scale, also show boundaries for places.

 A 4-digit numeric code is assigned by the Census  Bureau  to each
 place  in  alphabetic sequence within State.  "Place description"
 codes will also  generally  accompany place records.  These codes
 indicate  whether or not a place  is  incorporated,  as  well  as
 represent certain other information about the place.

 Data are summarized  for  all  places  in  STF's  1A  and  3A and
 PC80-1-A  reports.For places with 1,000 or more inhabitants, data
 are summarized in STF 2B, and PC80-1-B and HC80-1-B reports.For
 places with 2,500 or more, data are summarized  in STF 4B, PC80-1-C,
 and HC80-1-B reports.  In PHC80-3 reports, the  only  data  given for
 places are summaries for incorporated places.  In PHC80-2  Census
 Tracts reports and STF's 2A and 4A, summaries are presented  only
 for  places  with  10,000  or more inhabitants located in tracted
 areas.  Very detailed data are presented for all places which are
 central cities of SMSA' s in  PC80-1-D  reports,  and places with
 50,000  or  more  inhabitants  in  HC80-2  reports.  STF  5  also
 provides detailed data or places of 50,000 or more.

 The  files  and  reports  which  sequence  geographic   units  in
 hierarchical  fashion  must account for the fact that places  may
 cross the boundaries of counties, MCD's, and CCD's.  Such reports
 and tapes, therefore, provide  summaries for the various parts of
 places  created  when  places  are split  by  the  boundaries  of
 higher-level areas recognized in  the  hierarchy.   Specifically,
 place parts within county and MCD or CCD are presented  in STF 1A
 and  3A,  and  PC80-1-A.   Place parts within county and MCD  are
 presented for 20 specified States  in  STF  1B  and PHC80-1 Block
 Statistics  reports,  although the PHC80-1 reports  include  only
 places which have data collected for blocks.  In the remaining 30
 States, STF 1B and PHC80-1 reports subdivide places when split by
 county boundaries, but do not observe MCD or CCD boundaries.

 Historical   comparability:    Sixty-eight     percent   of   all
 incorporated  places  of  2,500  or  more made changes  in  their
 boundaries  between  1970  and  January 1,  1980,  which  is  the
 reference date for boundaries in  the  1980  censs.  In the 1970
 census,  ED  boundaries  were  drawn  so  as  to allow a user  to
 aggregate  1970  data for each city of 2,000 or more  inhabitants
 according to 1960  boundaries.  There will not be a corresponding
 capability in the 1980 census, because many of the municipalities
 are  now subdivided into  block  groups  and,  where  enumeration
 districts  are  still  used, the boundaries were often redrawn in
 response to local recommendations.

 In the 1970 and earlier censuses, CDP's were referred to as
 "unincorporated places." The name was changed to make it more
 explicit that such places are defined for census purposes, and to
 avoid confusion in States  where many "unincorporated places" are
 parts of incorporated towns or townships.  Many CDP's have been
 redefined since 1970.  Incorporated places which were newly
 incorporated or which changed  boundaries  between  1970 and 1980
 are listed in footnotes to table 4 of PC80-1-A.

 PLUMBING FACILITIES.  Presence of toilet facilities, bathing
 facilities, and piped water, ascertained for occupied  and vacant
 housing units.

     Complete plumbing for exclusive use.  Piped hot and cold water,
     a flush toilet, and a bathtub or shower for exclusive use by
     household members.  All facilities must be in the living
     quarters, but need not be in the same room. Hot water need not
     be available continuously.  A privy or chemical toilet is not
     counted as a flush toilet. A bathtub or shower is counted only
     if it is connected to piped running water.

     Lacking complete plumbing for exclusive use.

          Complete plumbing facilities, but also used by another
          household.  All facilities present, but with some or all
          of the plumbing facilities also regularly used by someone
          who is not a member of the household. This category also
          applies if the future occupants of living quarters now
          vacant would be expected to share the facilities.

          Some but not all plumbing facilities.  Units with one or
          two but not all three of these: hot and cold piped water,
          flush toilet, and bathtub or shower.

          No plumbing facilities.

 Historical comparability: Data on plumbing  facilities  have been
 collected since 1940. In 1970, there were separate questions on
 presence  of  hot  and cold running water, a flush toilet, and  a
 bathtub or shower.  The questions were combined in 1980.  In 1980
 complete facilities must not only be in the building, as in 1970,
 but also inside the housing unit.

 PUERTO  RICO AND OUTLYING  AREAS.   In  addition  to  the  United
 States, the  decennial  census  covers the Commonwealth of Puerto
 Rico and the outlying areas, including  American Samoa, Guam, the
 Trust  Territory of the Pacific Islands (including  the  Northern
 Mariana Islands which were legally part of the Trust Territory in
 1980), the  Virgin  Islands, and certain other small islands over
 which the United States  exercises  sovereignty  or jurisdiction,
 Questionnaire design and the questions asked were  developed  for
 Puerto   Rico  and  each  specified  area  to  accommodate  local
 conditions,  In  the case of the small islands, enumerations were
 not  conducted;  only   population   counts  obtained  from  U.S.
 Government records are published.

 The geographic subareas for which statistics  are  reported vary.
 Some  of  those noted below are defined in this glossary;  others
 will be defined in 1980 census reports for the areas.

      American Samoa:  villages, district subdivisions, districts,
      and islands.

      Guam:  census designated places and election districts.

      Puerto Rico:   blocks; ED's and BG's; census tracts and block
      numbering areas; subbarrios; zonas urbanas and aldeas; barrios,
      cuidades, and pueblos; municipios (county equivalents); SMSA'S,
      and SCSA's.

      Trust Territory of the Pacific Islands (including the Northern
      Mariana Islands):  census designated places, municipal districts,
      municipalities and islands, and administrative districts.

      Virgin Islands:  places, census subdistricts, and islands.

      Other islands:  no subdivisions.

 Data for Puerto Rico and its subdivisons will appear  in  reports
 and tapes in generally the same pattern as for States and their
 subdivisons.   Data for outlying areas will appear in 1980 Census
 of  Population, Volume  1,  and  Census  of  Housing,  Volume  1,
 reports.  Data will be available on computer tape only by special
 arrangement.

 Historical   compability:  The Canal Zone was not included in the
 1980 census because it was no longer under U.S. jurisdiction.

 Race-Region

 RACE.  All persons were asked to identify themselves according to
 the following  race  categories on the 1980 questionnaire: White,
 Black  or  Negro,  American   Indian,  Eskimo,  Aleut,  Japanese,
 Chinese, Filipino, Korean, Asian  Indian,  Vietnamese,  Hawaiian,
 Guamanian,  Samoan,  and  "other."  The "other" category includes
 Malayan, Polynesian, Thai, and other  groups  not included in the
 specific categories listed on the questionnaire.   This  item was
 asked on a complete-count basis.

 Counts  of  the  population by race in complete-count tabulations
 are provisional.   Final counts for race will be determined after
 the sample data have  been  processed.   The  sample  counts will
 first appear on tape in STF 3 and in print in Characteristics  of
 the  population,  General  Social  and  Economic Characteristics,
 PC80-1-C reports.

 The concept of race as used by the Census Bureau reflects self-
 identification by respondents; it does not denote any clear-cut
 scientific definition of biological stock.  Since the 1980 census
 obtained information on race through self-enumeration, the data
 represent  self-classification by people according  to  the  race
 with which they identify themselves.  For persons with parents of
 different races  who  could  not provide a single response to the
 race question, the race of the person's mother was used; however,
 if  a single response could not  be  provided  for  the  person's
 mother, he first race reported by the person was used.

 During   clerical  operations  on  all  questionnaires,  write-in
 responses  were  reviewed  in  an  attempt to classify entries to
 existing categories.  For instance,  if  the  "other"  circle was
 marked  and  accompanied by a write-in entry of "Caucasian,"  the
 "other" circle  was erased and the circle for "White" was filled,
 (additional examples are noted below.) However, Hispanic write-in
 categories such as  "Mexican"  or "Puerto Rican" were not recoded
 during complete-count processing, nor were Asian/Pacific Islander
 entries  such  as  "Cambodian, " "Indo-Chinese,  or  "Polynesian.
 During the subsequent  processing  of  sample questionnaires, all
 persons  in  the  "other"  category  with write-in  entries  were
 assigned codes which were recorded on the basic records.

 After   sample   coding,   categories   such   as    "Cambodian,"
 "Indo-Chinese,"  or  "Polynesian"  are collectively tabulated  as
 "Other  Asian and Pacific Islander" in  sample  tabulations  with
 detailed  race  categories  and added into the broader "Asian and
 Pacific Islander" category in  other  sample tabulations by race.
 This shifts a significant part of those cases tabulated as "other
 races" in complete-count data to "Asian  and Pacific Islander" in
 sample data and affects the comparability  between complete-count
 and sample data for these broad groups.

     White.  Persons who indicated their race as White, as well as
     persons who did not classify themselves in one of the specific
     race categories listed on the questionnaire but entered a
     response suggesting European origin  such as German, Italian,
     or Polish. (Persons who did not classify themselves in one of
     the specified race categories but wrote in entries such as Cuban,
     Puerto  Rican,  Mexican,  or  Dominican were included in the
     "other" race category; in the 1970 census most of these persons
     were included in the "White" category.)

     Black.   Persons  who indicated their race as Black or Negro,
     as well as persons who  did  not  classify  themselves  in one of
     the  specific  race  categories,  but  reported  entries  such as
     African,   Black   Puerto   Rican,  Creole,  Jamaican,  Nigerian,
     Trinidadian, or West Indian.

     American Indian, Eskimo, and Aleut:

          American Indian.  Persons who indicated their race as
          "Indian (American)"  or  who did not indicate a specific
          race category but reported the name of an Indian tribe.

          Eskimo.  Persons who indicated their race as "Eskimo."

          Aleut.  Persons who indicated their race as "Aleut."

     Asian and Pacific Islander.  In complete-count tabulations,
     includes all of the groups listed  below  except "Other Asian
     and Pacific Islander."  In sample tabulations, it  includes
     all of the groups listed below.

          Japanese.   Persons who indicated their race as Japanese,
          as well as persons who did not classify themselves in one
          one of the specific race categories, but entered a response
          such as Nipponese or Japanese American.

          Chinese.   Persons  who indicated their race as Chinese,as
          well as persons who did not classify themselves in one of the
          specific race categories, but reported entries such as
          Cantonese, Formosan, Taiwanese,  or Tibetan.

          Filipino.  Persons who indicated their race as Filipino,
          as well as persons who did not classify themselves in one of
          the specific race categories, but entered a response such as
          Filipino American or Philippine.

          Korean.  Persons who indicated their race as Korean, as well
          as persons who did not classify themselves in one of the
          specific race categories, but reported a response such as
          Korean American.

          Asian Indian.  Persons who indicated their race as Asian
          Indian, as well as persons who did not classify themselves
          in one of the specific race categories, but reported entries
          such as Bengali, Bharati, Dravidian, East Indian, Goanese,
          Hindu Indic, Kashmiri, or South Asian.

          Vietnamese.  Persons  who indicated their race as Vietnamese,
          as well as persons who did not classify themselves in one of
          the specific race categories, but reported a response such
          as Vietnam.

          Hawaiian.  Persons who indicated their race as Hawaiian. In
          the State of Hawaii, all persons who reported "Part-Hawaiian"
          were included in this category.

          Guamanian.  Persons who indicated their race as Guamanian,
          as well as persons who did not classify themselves in one of
          the race categories, but reported an entry such as Chamorro
          or Guam.

          Samoan.  Persons who indicated their race as Samoan, as well
          as persons who did not classify themselves in one of the
          specific race categories, but entered a response such as
          American Samoan or Western Samoan.

          Other Asian and Pacific Islander.  In sample tabulations
          only, persons who reported Burmese, Cambodian, Hmong, Indo-
          Chinese, Laotian, Micronesian, Okinawan, Pakistani,
          Polynesian, Siamese, Tahitian, Thai, or similar responses.
          In complete-count tabulations, this group is part of the
          "other races" category below.

 Other races.  Includes Asian and Pacific Islander groups not
 identified separately (e.g.,  Cambodian, Indo-Chinese, Pakistani,
 Indonesian, Fiji Islander) and other races not included in the
 specific categories listed on the questionnaire.  (Asian and
 Pacific Islander groups in the "other" category in 100-percent
 tabulations are included in the category "Asian and Pacific
 Islander" in sample tabulations.  Persons who wrote in "Mexican,"
 "Cuban," "South American," "Chicano," or "La Raza" remained in
 the "other" races category for both complete-count and sample
 tabulations.)

 In a few tables in which data for American Indian, Eskimo, Aleut,
 and Asian and Pacific Islander are not presented separately, the

     "other" category encompasses all race categories not shown
      separately.

      In some tabulations, the "other"  category is omitted to save
      space; data for this category are derivable by subtracting
      the sum of the specified race categories from the total.

 In certain printed tables, data for persons of Spanish origin are
 presented alongside data for as many  as  four major race groups.
 In such situations, users should not be misled  by  the proximity
 of  these  two  types  of  data.   Spanish  origin is not a  race
 category,  and  persons  of Spanish origin may be  of  any  race.
 Tabulations in a number of  sources  present  data separately for
 race categories (e.g., White, Black, and "other") for persons not
 of  Spanish  origin.   In addition, the number of  Spanish-origin
 persons is given by race.

 Limitations:   In  previous   censuses,   undercoverage   of  the
 population  has been associated with race. The 1970 census missed
 Blacks at a much  higher  rate  than  Whites.  The Bureau has not
 prepared undercoverage rates for races other than White or Black,
 because vital records and other sources of relevant statistics do
 not consistently distinguish among other races.

 Historical comparability:  Questions on  "race"  or  "color" have
 been asked in each census since 1790.  In 1970, when persons with
 parents   of   different   races   were  in  doubt  as  to  their
 classification, tne race of the father  was  used.   In 1980, the
 race of the mother was used for persons who could not  provide  a
 single response.  The 1970 category "Negro or Black" was retitled
 "Black  or  Negro."  Individual  categories for Vietnamese, Asian
 Indian,  Guamanian,  and  Samoan  were   added.    In  1970,  the
 categories Eskimo and Aleut appeared only on questionnaires  used
 in Alaska; they were replaced by Hawaiian and korean in all other
 States.   In   1980,   all   four   categories  appeared  on  the
 questionnaire.

 As  a  result  of the additions, the 1980  questionnaire  had  14
 specific race categories  instead  of  8  as  in  1970.  In 1970,
 persons who did not report a specific race but wrote  in Hispanic
 categories such as "Mexican," "Puerto Rican," or "Cuban"  in  the
 race  question  were  assigned  to  White; for 1980 these persons
 remain in the "other" race category.

 RACE OF HOUSEHOLDER. In all cases where occupied housing units,
 households, or families are classified by race, the race of the
 householder, i.e., the person in column 1, is used (see Household
 Relationship for the definition of Householder).  This item was
 determined on a complete-count basis.

 Since some households include persons  of  more  than  one  race,
 there  may  be  minor  differences  in counts by race between (1)
 tabulations  of  "families  by  family size"  or  "households  by
 persons in unit" where all persons are counted according to the
 race of householder and (2) tabulations of "persons in families"
 or   "persons  in households" where all persons are counted
 according to  their own race.

 Historical comparability:  Prior to 1980, the concept of "race of
 household  head"  was used instead of race of householder.   This
 change should not substantively affect the comparability of these
 data.

 REGION (CENSUS GEOGRAPHIC).  A large group of States which is a
 first-order subdivison  of the United States for census purposes.
 The four regions--Northeast, North Central, South, and West--are
 delineated in figure 10.   Regions  are  identified  by a 1-digit
 code.  Statistics  for  them  appear  in U.S. Summary reports  in
 almost every publication series, and in STF's 1C, 2C, 3C, and 4C.
 The  census  regions have no relationship  to  the  10   Standard
 Federal Administrative Regions.

 RENT, CONTRACT.  The monthly rent agreed to, or contracted for,
 regardless of any furnishings, utilities, or services that may be
 included.  Rent is shown for occupied units rented for cash and
 vacant units for  rent.   For  vacant  units,  rent is the amount
 asked for the unit at the time of enumeration, and  is  sometimes
 labeled  "rent  asked." Contract rent is tabulated for "specified
 renter-occupied"  units,  which  excludes one-family houses on 10
 acres  or more.  Respondents are to  report  rent  only  for  the
 housing  unit  enumerated  and  to  exclude  any  rent  paid  for
 additional  units  or for business premises.  The rent amount for
 the unit is to be reported  even  if  paid for by someone outside
 the household, or for some reason, not  paid.  Respondents who do
 not pay rent monthly are asked to ccnvert  the  sum  to a monthly
 average.  In the computation of aggregate and mean rent,  $35  is
 taken as the average of the interval "less than $50," and $550 is
 taken as the average of the interval "$500 or more.

      No  cash rent.  Rental units occupied without payment of cash
      rent. 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.

 Historical comparability:  Similar data have been collected since
 1930 (although the first full housing census did not occur until
 1940).   Rent intervals  reported  have  gone  to  higher  dollar
 figures in  recent  decades.   In 1970 question on rent had a top
 category of $300 or more; it also  listed  fewer  rent  intervals
 than  the  1980  question.  Constant dollar comparisons, 1970  to
 1980, are not prepared.

 RENTAL VACANCY RATE.  The number of vacant units for rent as a
 percent   of   the   total   rental   inventory--that   is,   all
 renter-occupied units and all year-round vacant units for rent.

 See also:  VACANCY STATUS

 ROOMS.  The number of whole rooms intended  for  living purposes,
 not  only  in  occupied housing units, but also in vacant  units.
 These  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, foyers,
 halls, half-rooms, utility rooms, unfinished attics or basements,
 or other space used for storage.  A partially  divided room, such
 as a dinette next to a kitchen or living 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.

 In  the  computation  of aggregate and mean rooms, 10 is taken as
 the average of the interval " 9 or more rooms."

 Historical comparability:  Similar data have been collected since
 1940.

 See also:  PERSONS PER ROOM

 SEX.  Ascertained on a complete-count basis.

 Historical comparability:   A  question on the sex of individuals
 has been asked of the total population in every census.

 SPANISH ORIGIN.  Counts of the population by Spanish origin in
 complete-count  tabulations are provisional.   Final  counts  for
 Spanish origin will be determined after the sample data have been
 processed. The sample  counts  will first appear on tape in STF 3
 and in print in in Characteristics  of  the  Population,  General
 Social and Economic Characteristics, PC80-1-C reports.

 Determined by a complete-count question which asks respondents to
 self-identify whether they are of Spanish origin or descent.   If
 when  interviewed the person reported a multiple origin and could
 not provide  a  single  origin, the origin of the person's mother
 was used. If a single response  was not provided for the person's
 mother, the first reported origin of the person was used.

 Persons marking any one of the four "Spanish" categories, i.e.,
 Mexican, Puerto Rican, Cuban, or  other Spanish, are collectively
 referred to as "persons of Spanish origin."

 In certain tabulations, persons of Spanish origin are further
 classified by type:

     Mexican.  Persons who indicated "Mexican, Mexican-American,
     Chicano," or wrote in an entry such as "La Raza."

     Puerto Rican.  Persons who indicated  "Puerto Rican" or wrote
     in an entry such as "Boricua.

     Cuban.  Persons who indicated "Cuban."

     Other Spanish. Persons who filled the circle for "other
     Spanish/Hispanic;" persons who wrote in  an origin or descent
     associated  with Spain, the Dominican Republic, or any Central
     or South America country except Brazil, or a nonspecific
     Spanish group such as "Spanish surnamed" or "Spanish speaking."

 Historical comparabiliy:   The  Spanish-origin question was asked
 on a 100-percent basis for the first  time  in  1980.   A similar
 question  was  asked  on the 1970 5-percent sample questionnaire.
 For 1980, the category  "no, not Spanish/Hispanic" appeared first
 (the corresponding category  appeared  last  in 1970).  Also, the
 terms  "Mexican-American"  and "Chicano" are added  to  the  term
 "Mexican." The category "Central  or South American," included in
 1970, has been dropped.

 Although a question on Spanish origin  was  included  in 1970, it
 was  not  the  major  identifier  used  to  classify the Hispanic
 population in the 1970 census as it is in 1980.  Depending on the
 area of the country, 1970 census data for  "persons of Spanish
 heritage"  were  variously  defined as "persons of  Puerto  Rican
 birth or parentage" in New York,  New  Jersey, and Pennsylvania);
 as "persons of Spanish language or Spanish  surname" (in Arizona,
 California, Colorado, New Mexico, and Texas);  and as "persons of
 Spanish language" (in the remaining 42 States and the District of
 Columbia).   Spanish  language referred to those persons  who  in
 1970 reported Spanish as  their mother tongue, as well as persons
 in  families  in  which the household  head  or  spouse  reported
 Spanish as his or her mother tongue.

 SPOUSE.  See HOUSEHOLD RELATIONSHIP

 STANDARD  CONSOLIDATED   STATISTICAL   AREA   (SCSA).    A  large
 concentration of metropolitan population composed of two or  more
 contiguous standard metropolitan statistical areas (SMSA's) which
 together   meet   certain  criteria  of  population  size,  urban
 character, social and  economic integration, and/or contiguity of
 urbanized areas.  Each SCSA must include at least one SMSA with a
 population of one million  or  more.   Thirteen  SCSA's  were  in
 existence  at the time of 1980 census, having been defined by the
 Office of Federal  Statistical  Policy and Standards according to
 criteria  published  by  that  office  in  Standard  Metropolitan
 Statistical  Areas:   1975.  Four  additional  SCSA's  have  been
 defined Based on 1980 census results.

 SCSA's are identified by a 2-digit numeric code.  Summaries for
 SCSA's appear in many reports and in STF's 1C, 2C, 3C, and 4C.
 Summaries  are  generally   provided  for  SCSA  totals  and  for
 within-State parts of SCSA's.

 Historical comparability:  The  original  13 SCSA' s were created
 in  1976.   For  the  1960  and 1970 censuses the  Census  Bureau
 recognized two "Standard Consol  idated  Areas"  (SCA's)  , which
 were metropolitan complexes around New York and Chicago.

 In 1982 or 1983, the SCSA concept will be replaced by the new
 Consolidated Metropolitan Statistical Area (CMSA) concept, with
 somewhat more flexible criteria, as spelled out in the Federal

 Register,  January  3,  1980.   These  changes  will  not  affect
 publication of 1980 census data for SCSA's.

 STANDARD   METROPOLITAN   STATISTICAL   AREA   (SMSA).   A  large
 population nucleus nearby communities which have a high degree of
 economic  and  social integration with that nucleus.   Each  SMSA
 consists of one  or  more entire counties (or county equivalents)
 that meet specified standards pertaining to population, commuting
 ties, and metropolitan  character.   In  New  England,  towns and
 cities,  rather than counties, are the basic units and should  be
 substituted  for  "counties"  where  counties  are  cited  below.
 SMSA's are designated by the Office of Federal Statistical Policy
 and Standards.

 Data  products  from  the  1980 census will report on 323 SMSA's:
 (1) 287 defined before January  1,1980  (including  4  in  Puerto
 Rico);  and  (2) an additional 36 established as a result of 1980
 census population counts.  The 36 new SMSA's were designated when
 1980 counts showed  that  they  met  one or both of the following
 criteria:

     1.   Included a city with a population  of  at  least  50,000
          within its corporate limits, or

     2.   Included  a Census Bureau-defined urbanized area (which
          must have a population of at least 50,000) and a total
          SMSA population of at least 100,000 (or in New England
          75,000).

 An SMSA includes a city and, generally its entire UA and the
 remainder of the county or counties in which the UA  is  located.
 An  SMSA  also  includes  such additional outlying counties which
 meet specified criteria relating  to  metropolitan  character and
 level of commuting of workers into the central city or  counties.
 Specific  criteria  governing the definition of SMSA's recognized
 before 1980 are published  in  Standard  Metropolitan Statistical
 Areas: 1975, issued by the Office of Federal  Statistical  Policy
 and Standards.

 With two exceptions, each SMSA has one or more central cities, up
 to a maximum of three, and the names of these cities comprise the
 title  of  the  SMSA,  The Nassau-Suffolk, NY SMSA has no central
 city; and the title of the  Northeast  Pennsylvania SMSA does not
 contain  the  names  of  its  three  central  cities:   Scranton,
 Wilkes-Barre, and Hazleton.

 SMSA's  are  identified  by  a FIPS 4-digit numeric  code,  which
 follows  the alphabetic sequence  of  SMSA  names.   SMSA's  are
 outlined on small-scale maps in several 1980 report series.  SMSA
 data appear  in  most  1980  census publications and summary tape
 files.   Many  SMSA's  cross State  boundaries,  and  reports  in
 several  series  provide  summaries   or   the   State  parts  of
 multi-State  SMSA's, as well as SMSA totals. Summary  tape  files
 present data only  for  State  Parts  of  SMSA' s, except for the
 "national" files:  STF's 1C, 2C, 3C, and 4C.

 Hisorical comparability:  A comparison of 1970 and 1980 census
 products reveals two typies of changes in metropolitan territory.
 First, 69 new SMSA's were created from previously nonmetropolitan
 territory:   36  were  defined in 1981 based on  1980  population
 counts and 33 were defined between 1973 and 1979 based on current
 population estimates.  (An  additional  SMSA--Rapid City, SD--was
 provisionally recognized based on population  estimates,  but  it
 did not qualify according to 1980 census data.)

 The  second component of change to metropolitan territory between
 1970 and  1980  was  the redefinition of many of the SMSA's which
 were recognized in 1970  census  tabulations.   Of  the  247 1970
 SMSA's, 101 were redefined in 1973 based on 1970 census commuting
 data,  most  the  addition  of  1  or more counties (or towns and
 cities in New England).  In addition,  one  SMSA was redefined by
 the  addition  of one area and the deletion of  another  (Wichita
 Falls,  Texas),  one  was  subdivided  (Nassau-Suffolk  SMSA  was
 created from a part  of  the New York SMSA), four pairs of SMSA's
 were combined into single SMSA's (for example, Dallas-Fort Worth,
 Texas), and four SMSA's lost area that was added to other SMSA's.
 In addition, the names of  several  SMSA's  were changed in 1973,
 one  in  such  a  way  that  the  SMSA  code  also  changed  (San
 Bernardino-Riverside-Ontario to Riverside-San Bernardino-Ontario,
 California).

 Since SMSA's are always defined in terms of whole counties (towns
 or cities in New England) for which extensive data are available,
 users can usually compile figures for comparisons over time.

 In 1982 or 1983, SMSA boundaries will be re-evaluated  using 1980
 census  data on commuting, labor force, population density,  type
 of residence,  and  population  growth, according to new criteria
 spelled out in the Federal Register,  January  3,  1980 (vol. 45,
 no.  2, pt. VI).  At that time new outlying counties nay be added
 or  existing  ones deleted, some area titles will be changed  and
 some new central  cities  will  be designated, so'ne areas may be
 consolidated and a new SMSA's may  be created.  Further, the term
 "standard metropolitan statistical area"  will  be  shortened  to
 "metropolitan  statistical  area"  (MSA).  These changes will not
 affect publication of 1980 census data for SMSA's.

 State-Urbanized Area

 STATE.   A  major  political  unit  of the  United  States.   The
 District of Columbia is treated as a State-equivalent in all 1980
 census data series; Puerto Rico, Virgin  Islands, American Samoa,
 Guam, and Trust Territory of the Pacific Islands are also, except
 that they do not appear in P.L. 94-171 Population Counts file.

 States are identified by a 2-digit FIPS code which follows the
 alphabetic sequence of State names, and by a 2-digit Census
 Geographic State code, the first digit of  which  identifies  the
 census division of which the State is a part.

 Historical comparability:  There have been no significant changes
 to States boundaries in the last decade.

 STATE  ECONOMIC AREA (SEA).  A single county or group of counties
 within a State which is relatively homogeneous with respect to
 economic and social characteristics.  The grouping of the 3,103
 counties or county equivalents in 1950 into SEA's was the product
 of a special  study  prepared  by  the  Bureau  of  the Census in
 cooperation with the Bureau of Agricultural Economics apd several
 State  and  private  agencies.  Boundaries were drawn in  such  a
 manner  that  each  economic   area   had   certain   significant
 characteristics  which  distinguished  it  from  adjoining areas.
 There are 510 SEA's.

 SEA's are identified in census tabulations on computer  tape by a
 2-digit   numeric   code  or  a 1-digit alphabetic code, assigned
 sequentially  within  the   State;  however,  no  1980  data  are
 tabulated for SEA's.

 Historical comparabliity:  SEA boundaries have remained largely
 unchanged since they were defined  in  1950.   In 1950, 501 areas
 were defined; in 1960, 509; and in 1970, 510.

 TENURE.   The  classification  of  all occupied units  as  either
 owner-occupied  or  renter-occupied,  This   item  was  asked  on
 acomplete-count basis.

      Owner-occupied.  Reported as "owned or being bought" by someone
      in the household even if the unit is mortgaged or not fully
      paid for.

      Renter-occupied.  All occupied housing units which are not
      owner-occupied, regardless of whether or not cash rent is paid by
      a member of the household, ("No cash rent" units, included here,
      are separately identified in rent tabulations.)

 Historical comparabiliy: Tenure has been  collected  since  1980.
 In  1970,  the  question  on  tenure also included a category for
 condominium and cooperative ownership.  In 1980, condominiums are
 identified in a separate question.

 TRACT.  See CENSUS TRACT

 UNITED STATES.  This designation includes the 50 States and the
 District of Columbia.  1980 STF's and most report series (usually
 in a separate U.S. Summary report)  provide  data  summarized for
 the United States.

 UNITS AT ADDRESS.  Number of housing units with a particular house or
 building address number.This question is asked  principally to improve
 census  coverage. If the respondent indicated from 2 to 9 units at the
 address,  census  workers  checked  the  number against the
 number  of  units,  for  that  address  on  the  Bureau's address
 register.  If  the respondent's answer was higher than  what  was
 shown  in the address  register,  the  building  was  visited  to
 ascertain   the   correct   number  of  units,  thereby  assuring
 enumeration of every unit.

     Mobile home or trailer.  Included if intended for occupancy
     where located. Mobile homes or trailers were counted whether
     mounted or on wheels.

 Limitations:   Data  users  sometimes use "units at address" as a
 proxy for "units in structure,"  which is published later because
 it  is  based  on  a  sample  question.   The  concepts  are  not
 interchangeable, though, since  some  multi-unit  buildings  have
 more  than  one address and there is some variation in respondent
 interpretation of "units at address."

 Historical comparabllity: Similar data were collected in 1970.

 UNITS, PERSONS  IN.   The number of persons living in the housing
 unit. All occupants are  counted-not  just  those  related to the
 householder,  but also any lodgers, roomers, boarders,  partners,
 wards, foster children,  and  resident  employees  who  share the
 living quarters.

 UNRELATED INDIVIDUAL.  An unrelated individual may be (1) a
 householder living alone or only with persons not related  to him
 or  her,  (2)  a  roomer, boarder, partner, roommate, or resident
 employee unrelated  to  the  householder, or (3) a group quarters
 resident who is not an inmate  of an institution.  Classification
 as  an  unrelated  individual  derives  from  the  complete-count
 question  on  household  relationship.    Examples  of  unrelated
 individuals include a widow who occupies her  house alone or with
 one  or  more  other  persons  not related to her, a  roomer  not
 related to the householder, a maid  living  as  a  member  of her
 employer's  household,  and  a resident staff member living in  a
 hospital dormitory.  Persons living with one or more relatives in
 a household where the householder  is  not related to any of them
 are  classified  in  the  census  as unrelated  individuals;  for
 example, a husband and wife who rent a room from a householder to
 whom they are not related.

 Historical comparability: A similar concept was used in 1970.

 URBAN AND RURAL (POPULATION).  Urban and rural are type-of-area
 concepts rather tnan specific areas outlined on maps.  As defined
 by the Census Bureau, the urban population  comprises all persons
 living in urbanized areas (UA's) and in places  of  2,500 or more
 inhabitants outside UA' s.

 The  rural  population  consists  of everyone else.  Therefore  a
 rural classification need not imply  farm residence or a sparsely
 settled area, since a small city or town  is  rural as long as it
 is outside a UA and has fewer than 2,500 inhabitants.

 The terms urban and rural are independent of metropolitan and
 nonmetropolitan  designations; both urban and rural  areas  occur
 inside and outside SMSA's.

 Historical  comparability:  Except for the minor relaxation of UA
 criteria discussed below, urban  and  rural definitions have been
 consistent  since  1950, Within small counties,  measurements  of
 urban  and  rural populations  over  time  may  be  significantly
 affected by the  increase  or  decrease  of  a place's population
 across the 2,500 population threshold, e.g., the  increase  of  1
 person  to  a  palace of 2,499 results in an increase of 2,500 to
 the county s urban population.

 URBAN FRINGE.  See URBANZED AREA

 URBANIZED AREA (UA).  A  population  concentration  of  at  least
 50,000  inhabitants,  generally  consisting of a central city and
 the surrounding, closely settled, contiguous territory (suburbs).

 The UA criteria define a boundary based primarily on a population
 density  of at least 1,000 persons  per  square  mile,  but  also
 include some  less densely settled areas within corporate limits,
 and such areas  as  industrial  parks and railroad yards, if they
 are within areas of dense urban development.   The  density level
 of  1,000  persons per square mile corresponds approxiinately  to
 the continuously built-up area around a city.  The "urban fringe"
 is that part of the UA outside of a central city.

 Typically, an  entire UA is included within an SMSA.  The SMSA is
 usually much larger in terms of territory covered and includes
 territory Where the population density is less than 1,000.
 Occasionally, more  than  one  UA  is located within an SMSA.  In
 some  cases  a  small  part of a UA may  extend  beyond  an  SMSA
 boundary and possibly into  an  adjacent  SMSA.   A few 1980 UA's
 will  be  defined  in  areas which do not meet the 100,000  total
 population criterion for  SMSA designation.  UA's may cross State
 boundaries.  In a few cases  a  UA  does  not  include  all of an
 "extended"  city,  that is, a city which is determined to have  a
 significant amount of rural territory.

 UA's are identified by 4-digit codes, which follow the alphabetic
 sequence or all UA names.   When  a  UA  has  the same name as an
 SMSA,  the UA code is the same as the SMSA code.   UA  boundaries
 are shown  on final MMS/VMS maps, and at much smaller scale on UA
 outline maps in PC80-1-A and HC80-1-A reports.

 Historical comparability:  Because  UA's are defined on the basis
 of population distribution at the time  of  a  decennial  census,
 their  boundaries tend to change following each census to include
 expanding urban development.

 The criteria  have  been  fairly constant since 1950, although in
 each decade some new refinements  have  been added.  For the 1970
 census, in which 252 UA's were recognized,  it  was necessary for
 the central city to have a population of 50,000 or  more,  or for
 there to be "twin cities" with a combined population of 50,000 and
 with the smaller city having at least 15,000. In 1974 the criteria
 were liberalized  to  allow  UA  recognition to certain cities between
 25,000 and 50,000, and this resulted  in  27 new urbanized areas.
 For 1980, no minimum population size is required  for  a  central
 city.

 Vacancy, Duration of-Year Round Housing Units

 VACANCY, DURATION OF.  The period from the departure of the  last
 occupants  until  Census  Day--not  the whole time the unit might
 stay vacant.  For newly constructed units,  never  occupied,  the
 period extends from the date of completion until Census Day.

 Historical comparability:  Similar data have been collected since
 1960.

 See also:  VACANCY STATUS

 VACANCY STATUS.  Determined for housing units at the time of
 enumeration.  Vacancy status pertains to year-round vacant units.
 Vacancy status  and  other  characteristics  of  vacant units are
 determined   by   enumerators   questioning   landlords,  owners,
 neighbors, rental agents, and others.

 Included  in  the  housing inventory are vacant mobile  homes  or
 trailers intended to  be  occupied  on the site where they stand.
 Vacant mobile homes on dealer sales lots  or in storage yards are
 not counted as housing units.

 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 open  to  the  elements; that is, if
 the roof, walls, windows, or doors no longer protect the interior
 from the rain or snow, or if there is positive  evidence (such as
 a  sign  on  the house or in the block) that the unit  is  to  be
 demolished or is condemned. 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.

     Vacant year-round units.  Vacant units intended for use, even
     if only occasionally, throughout the year.

         For  sale  only.   Vacant  year-round units offered for sale
         only. The category includes mainly one-family houses,  but
         also two types of vacant units in multi-unit buildings:
         (1) vacant units (which are  for sale only) in a cooperative
         or condominium and (2) vacant units intended to be occupied
         by the new building owners in multi-unit buildings that are
         for sale. Vacant units offered for rent or sale at the same
         time are classified as "for rent."

         For rent.  Vacant year-round units offered for rent, and
         vacant units offered for rent or sale at the same time,
         including vacant units for rent in a building for sale.

         Rented or sold, awaiting occupancy.  Vacant year-round
         units sold or rented but still unoccupied when enumerated--
         including units where rent is agreed on but not yet paid.

         Held for occasional use.  Vacant  units  for  weekend or
         other occasional use throughout the year.

         Other vacant.  Vacant units for year-round occupancy  not
         classified above, for example, units held for a janitor
         or caretaker, settlement of an estate, pending repairs
         or modernization, or personal reasons of the owner.

     Vacant seasonal and migratory units.   Vacant units used or
     intended for use only during certain seasons.   Any unit used
     throughout  the  year,  even  if  only occasionally, is excluded.
     Seasonal units include those for summer or winter sports or
     recreation-beach cottages and hunting cabins, for example.
     Seasonal units may also include  quarters for such workers as
     herders and loggers. Migratory units include those for farm
     workers during crop season.

 Limitations:  Most tables exclude vacant  seasonal  and migratory
 units  since  information  on  characteristics  of such units  is
 difficult to obtain.

 Historical comparability:  Similar data have been collected since
 1940, In 1970, seasonal and migratory vacant units  were reported
 in two separate categories.

 VALUE.   For   Owner-occupied  housing  units,  the  respondent's
 estimate of the current dollar worth of the property.  For vacant
 units, value is  the price asked for the property.  Statistics on
 value are shown only for owner-occupied condominium units and for
 "specified owner-occupied"  units,  i.e.  ,  one-family houses on
 less than 10 acres and with no business on the  property.   Value
 tabulations   exclude  renter-occupied  units,  mobile  homes  or
 trailers, houses  on  10  or more acres, houses with a commercial
 establishment   or   medical  office   on   the   property,   and
 noncondominium   units   in    multi-family    buildings    (e.g.
 cooperatives).

 A property is defined as the house and land on which it stands.
 Respondents  estimated  the  value of house and land even if they
 only owned the house or owned the property jointly.

 When value data are presented  solely  for  vacant units for sale
 only,  the  term  "sale  price  asked"  is substituted.   In  the
 computation of aggregate and mean value,  $7,500  is taken as the
 average  of  the  interval  "less than $10,000," and $250,000  is
 taken as the average of the interval "$200,000 or more."

 Limitations.   A  1970  census  evaluation   study   found   that
 respondents  tended  to  report  a  higher  value  of  home  in a
 reinterview  survey,  with  more  detailed questions, than in the
 census.  On the other hand, a comparison  of  1970 census reports
 of value with subsequent actual sale prices of  a sample of homes
 sold one to two years later found that the census understated the
 median  market  value  of  those  homes  by  only  three  percent
 (compared to the sale prices adjusted for inflation  between  the
 census  and sale date).  This result cannot be generalized to all
 census value  data,  however,  since the sample was restricted to
 metropolitan areas, and since census  respondents  who were about
 to sell their homes may have been more aware of market values.

 Historical comparability:  Similar data have been collected since
 1930 (and in 1920 for mortgaged nonfarms only), but value for
 condominiums  is  new  for  1980.   For historical comparability,
 tables  will  show  condominiums and noncondominiums  separately.
 Values for 1980 reflect  increased  housing  prices:  the highest
 category  was  "$50,000 or more" in 1970.  Also,  the  number  of
 categories increased from 11 in 1970 to 24 in 1980.

 WARD.  Political subdivision of a city used for voting and
 representation  purposes.    For   1980,   in  approximately  200
 nonblock-numbered  places ward boundaries were  observed  in  the
 definition of enumeration  districts  (ED's).  For  these  areas,
 users may prepare ward data by summarizing ED data. In areas with
 block  statistics,  users  may  prepare  ward data by summarizing
 block data.

 Historical comparability:  Population counts  for wards in places
 with  a  population  of 10,000 or more appeared in  Supplementary
 Reports, PC-S1, in 1960 and 1970.

 WHITE POPULATION.  See RACE

 YEAR-ROUND HOUSING UNITS.  All occupied units plus vacant units
 intended for year-round use.  Almost all data on housing
 characteristics are limited  to  year-round  units.  Vacant units
 held for seasonal use or migratory labor are excluded  because it
 is difficult to obtain reliable information for them.  Counts  of
 the  total housing inventory include both year-round and seasonal
 units.
