    a separate data set in the public-use file. 
    This tape documentation was prepared in the Division of Vital Statistics.  
    Manju Sharma of the Systems, Programming,and Statistical Resources Branch 
    was responsible for developing the natality documentation and for providing 
    all of the computer programming services necessary to keep it up-to-date.

    Documentation of the Detail Natality Data File for 1996 Data
    Since 1985 natality statistics for all States and the District of Columbia 
    have been based on information from the total file of records.  The inform-
    ation is received on computer data tapes coded by the States and provided to 
    the National Center for Health Statistics (NCHS) through the Vital Statistics
    Cooperative Program.  NCHS receives the data for this file from the 
    registration offices of all States, the District of Columbia, and New York 
    City.  Natality data for Puerto Rico, Virgin Islands, and Guam are included 
    as separate data-set in the public-use file.
    Natality data for the United States are limited to births occurring within the 
    United States to U.S. residents and nonresidents.  Births to nonresidents of 
    the United States are excluded from all tabulations by place of residence.  
    Births occurring to U.S. citizens outside the United States are not included 
    in this file.  Natality data for Puerto Rico, Virgin Islands, and Guam are 
    limited to births occurring with in the respective territories.
    Effective January 1, 1989, a revised U.S. Standard Certificate of Live Birth 
    replaced the 1978 revision. The 1989 revision provides a wide variety of new 
    information on maternal and infant health characteristics, representing a 
    significant departure from previous versions in both content and format.  
    For a more detailed discussion of the revised and new items refer to the 
    technical appendix part of this document.
    The Office of Management and Budget revised its designation of metropolitan 
    statistical areas based on figures from the 1990 Census.  Effective with the 
    1990 data file, NCHS has been using these new definitions and codes as indicated 
    in the listing of 320 Metropolitan Statistical Areas (MSA's), Primary Metro-
    politan Statistical Areas (PMSA's), and New England County Metropolitan Areas 
    (NECMA'S) included in this documentation.  There are also 20 Consolidated
    Metropolitan Statistical Areas (CMSA's), which are made up of PMSA's. Because 
    other geographic changes based on 1990 Census became effective with 1994 data 
    file, the metropolitan statistical area destination were updated as well.
    Effective with the 1994 data-file there are 311 MSA's, PMSA's, and NECMA'S 
    and 18 CMSA's as indicated in the listing included in this documentation. 
    NCHS has adopted a new policy on release of vital statistics unit record data 
    files.  This new policy was implemented for the 1989 vital event files to 
    prevent the inadvertent disclosure of individuals and institutions.  As a 
    result, the files for 1989 and later years do not contain the actual day of 
    the birth or the dates of birth of the mother or father.  The geographic detail 
    is also restricted; only counties and cities of 100,000 or more population 
    based on the 1990 Census, as well as metropolitan areas of 100,000 or more 
    population based on the 1990 Census, are identified.

    Vital Statistics Geographic Code Outline for the United States
    The following pages show in detail the geographic codes used by the Division 
    of Vital Statistics in the processing of vital event data occurring in the 
    United States.  When an event occurs to a nonresident of the United States, 
    residence data are coded only to the "State" level; several western hemisphere 
    countries or the remainder of the world are uniquely identified.  Along with 
    the Division of Vital Statistics codes the Federal Information Processing 
    Standards (FIPS) codes are shown for several items. Both sets of codes 
    appear on the vital event public-use files.  The Metropolitan Statistical 
    Area codes are effective with the 1996 data year and are based on the 1990 
    Census.
    To aid the user in interpreting the geographic codes, a brief explanation of 
    the codes and of the column headings/abbreviations shown on the following 
    pages are:
    State (St): Each State and the District of Columbia are numbered alphabetically. 
                In addition, several unique codes are used to identify nonresidents of the U.S. 
    County (Cnty): Counties and county equivalents (independent and coextensive 
                   cities) are numbered alphabetically within each State.
    P/MSA: Primary metropolitan statistical areas and metropolitan statistical 
           areas are those established by the U.S. Office of Management and 
           Budget (OMB) using 1990 Census population counts.  For New England, 
           the New England County Metropolitan Areas (NECMA) are used.
    M/NM: Metropolitan counties (code 1) are component counties of P/MSA's.  
          Nonmetropolitan counties (code 2) are not part of any P/MSA.                       
    City or place: Cities/places are numbered alphabetically within each State 
                   and identify each city with a population of 10,000 or more 
                   in 1990.
    P/S: Population size code for city of residence based on the 1990 Census.  
         Refer to the code outline given earlier in this document for specific 
         codes and meanings.
    Name: Each State, county, and city name is listed along with its respective 
          code.  In addition, places used to identify nonresidents of the U.S. 
          are also listed along with their codes.
    FIPS: For an explanation of FIPS codes, reference should be made to various 
          National Bureau of Standards (NBS) publications.
    So! How do I find Yavapai county, Arizona; or Tupelo city, Mississippi?  
    
    Since counties and cities/places are numbered within State, the State and 
    county or the State and city/places codes must be used to select these areas.  
    It is most helpful if the county is known when looking for a particular city 
    since areas are shown by State, county, and city.
    Yavapai county, Arizona - State and county codes NCHS: 03 014; FIPS: 04 025.
    Tupelo, Mississippi - State and city/place codes NCHS: 25 032; FIPS: 28 74840; 
    or State, county, city/place codes
    
    NCHS:  25 041 032; FIPS: 28 081 74840.
