DOCUMENTATION OF THE DETAIL NATALITY TAPE FILE FOR 1995 DATA
Technical Appendix - Natality
SPECIAL NOTICE:
The Geographic Codes were changed effective with 1994 data to reflect the
results of the 1990 Census.
Detail Natality for Puerto Rico, Virgin Islands, and Guam are included as
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.
Sally Curtin of the Reproductive Statistics Branch prepared the Technical
Appendix. The Registration Methods Section and the Data Acquisition and
Evaluation Branch provided consultation to State Vital Statistics offices
regarding collection of birth certificate data.
Questions on the documentation or general questions concerning the natality
file should be directed to the of the Systems, Programming, and Statistical
Resources Branch, Division of Vital Statistics, NCHS, 6525 Belcrest Road,
Room 840, Hyattsville, MD 20782 (301-436-8900).
Questions concerning the Technical Appendix or substantive questions
concerning the natality data should be directed to the Reproductive

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.
Vital Statistics Geographic Code Outline for Puerto Rico, Virgin Islands and
Guam

state, 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. Codes
are effective with the 1994 data year and are based on results of the 1990
Census.

Nonmetropolitan counties (code 2) are not part of any P/MSA.
City or Place: No city/places in Puerto Rico are identified.
Name: Puerto Rico and each municipo are listed along with their respective
codes. In addition, places used to identify nonresidents of Puerto
Rico are also listed along with their codes.
FIPS: For an explanation of FIPS codes, reference should be made to various
National Institute of Standards and Technology (NIST) publications.
Virgin Islands:
State (St): The Virgin Islands has its own unique code. In addition, several
unique codes are used to identify nonresidents of the Virgin Islands.
