                   Beginning with 1992 data, some areas started reporting additional 
                        Asian or Pacific Islander codes for race.  Codes 18-68 replace old 
                        code 08 for these areas.  Code 78 replaces old code 08 for all other 
                        areas.  For consistency with Census race code 09 (all other races) 
                        used prior to 1992 has been imputed.

                   Beginning with 1992 data, some areas started reporting additional 
                        Asian or Pacific Islander codes for race.  Codes 18-68 replace old 
                        code 08 for these areas.  Code 78 replaces old code 08 for all other 
                        areas.  For consistency with Census race code 09 (all other races) 
                        used prior to 1992 has been imputed.

  80-87      8           BIRTHWEIGHT
                    Beginning in 1995, an imputation for not-stated birthweight 
                         was added to reduce potential bias in the data (see section 
                         on Changes beginning with the 1995 data year in the introductory 
                         text to this documentation). The following imputation flag can 
                         be used to delete imputed values for those researchers
                         wishing to use only reported birthweight data.

                    This variable is included in the denominator file only, and identifies 
                         a record which is also included in the numerator file.  Please note 
                         that not all infant deaths in the numerator file are represented in 
                         the denominator file, because some of the infants who died in 1996 
                         were born in 1995.

                           birth and/or death is unknown, the age is imputed.

                         Record weight
                      Beginning in 1995, a record weight was added to the  linked file 
                           to adjust for the approximately 2-3% of  records each year which 
                           cannot be linked to their corresponding birth certificates (see 
                           introduction to this tape documentation for further details).  
                           These weights are used to produce all NCHS linked file tables,
                           including Documentation tables 1-5 included in this tape documen-
                           tation. The general format for this record weight is the number one 
                           followed by a decimal point and six decimal places as follows:

Geographic Code Outline
The following pages show the geographic codes used by the Division of Vital Statistics in the
processing of vital event data occurring in the United States.  For the linked data set, counties and cities
with a population of 250,000 or more are identified. 
Federal Information Processing Standards (FIPS) State, County, and City/Place Codes:  For the 1996
linked file, the county and city/place codes and the State code immediately preceding them are FIPS
codes.  These codes were effective with the 1994 data year and are based on the results of the 1990
Census. County and county equivalents (independent and coextensive cities) are numbered
alphabetically within each State.  When an event occurs to a nonresident of the United States, residence
data are coded only to the "State" level, or to the remainder of the world.  For an explanation of FIPS
codes, reference should be made to various National Bureau of Standards (NBS) publications.



1996 ADDENDUM TO "TECHNICAL APPENDIX" OF VITAL STATISTICS OF THE    
UNITED STATES: MORTALITY, 1994
 To assist the users of the mortality public-use data tapes, attached is a copy of the "Technical
Appendix" of the Vital Statistics of the United States: Mortality, 1994.  This technical appendix
provides certain qualifications that are essential to using, analyzing, and interpreting the data on those
tapes.  Certain modifications to the technical appendix are essential to make it applicable to the
mortality file for the 1996 data year.  Those modifications include the following:  
I. Sources of data
   State-coded medical data
    1996          Utah
    1995          New Mexico
           
    For 1996, of the States in the VSCP, 42 States submitted precoded medical data for all
    death certificates in the form of electronic data files. Of these 42 States, Maine, Montana, North
    Dakota, and Wyoming contracted with a private company to provide NCHS with precoded
    medical data. The remaining eight VSCP States, New York City, and the District of Columbia
    submitted copies of the original certificates from which NCHS coded the medical data.
    For 1996 approximately 29 percent of the Nation's death records were multiple-cause coded
    using SuperMICAR and 71 percent using MICAR.  This represents data from 22 States which
    was coded by SuperMICAR and data from 28 States, the District of Columbia, and New York
    City which was coded by MICAR.
  
    All States submitted precoded demographic data for all death certificates in the form of
    electronic data files in 1996.
    Data for Puerto Rico, the Virgin Islands, and Guam are included on the mortality public-
    use data tapes.  These data were included for the first time for 1994.
II. Classification of data
   A. Hispanic origin
     Data for 1996 were obtained from the District of Columbia and all States except Oklahoma,
     which was excluded because the death certificates did not include an item to identify Hispanic
     or ethnic origin.           
     Infant mortality--Infant mortality data by Hispanic origin are based on deaths to residents of
     the same 49 states and the District of Columbia.  In computing infant mortality rates, deaths
     and live births of unknown origin are not distributed among the specified Hispanic and non-
     Hispanic groups.
     Infant mortality rates by Hispanic origin may be biased, because of inconsistencies in
     reporting Hispanic or ethnic origin between the birth and death certificates for the same infant. 
     Estimates of reporting bias may be made by comparing rates based on the linked file of infant
     deaths and live births (1) with those where the Hispanic or ethnic origin of infant death is
     based on information from the death certificate (2).  Because of these biases, it is preferable to
     calculate Hispanic mortality rates for infants using the file of linked infant death and live birth
     records (1).
     In 1990 the 49 States and the District of Columbia accounted for about 99.6 percent of the
     Hispanic population in the United States, including about 99.5 percent of the Mexican
     population, 99.8 percent of the Puerto Rican population, 99.9 percent of the Cuban population,
     and 99.7 percent of the "Other Hispanic" population (3). 
   B. Educational attainment
     Deaths by educational attainment are included on the 1996 public use data tapes.  These
     data were included for the first time for 1989.  It is recommended for 1996 that analyses of
     educational attainment data include deaths to residents of 45 States and the District of
     Columbia whose data were approximately 80 percent or more complete on a place-of-
     occurrence basis.  While data for Kentucky are included on the data tape, they would be
     excluded from analyses because more than 20 percent of their death certificates were classified
     to "unknown educational attainment."  Data for Georgia, Oklahoma, Rhode Island, and South
     Dakota were excluded from the data tape because their death certificates did not include an
     educational attainment item.
          
   C. Occupation and industry
     Deaths by occupation and industry are included on the 1996 public-use data tapes.  These
     data were included for the first time for 1985.  These data were obtained from the following
     items that appear on the U.S. Standard Certificate of Death:
       o    (Item 14a)  USUAL OCCUPATION (Give kind of work done during most of working
                                          life, even if retired.) 
       o     (Item 14b) KIND OF BUSINESS OR INDUSTRY
     For 1996, the occupation and industry mortality data were  included for the following 19
     reporting States:
              Colorado              New Mexico
              Georgia               North Carolina
              Hawaii                Ohio
              Idaho                 Rhode Island
              Kansas                South Carolina
              Kentucky              Utah
              Maine                 Vermont
              Nevada                West Virginia
              New Hampshire         Wisconsin 
              New Jersey    
          
     Data for 1993-96 were coded using the revised NCHS Part 19 instruction manual (4) and
     the Bureau of the Census 1990 occupation and industry titles and three-digit codes, which are
     shown in the 1990 Census of Population and Housing(5).      
     Occupation and industry mortality data for 1984-92 were based on the 1980 Bureau of the
     Census occupation and industry classifications. For a listing of the changes between the 1980
     and the 1990 classification systems, see Appendix D of the NCHS Part 19 instruction
     manual(4).
     In addition to the codes shown in the Bureau of the Census publication(5), the following
     special codes were created:
       Occupation                 Industry
              913 Retired; with no       961 Own Home/At Home
                                              other occupation   970 Retired: with no other
                                                   reported                   Industry reported
              914 Housewife/             990 Blank, Unknown, NA
            Homemaker             
              915 Student
              916 Volunteer
              917 Unemployed, never   
                  worked, disabled, 
                  child, infant
              999 Blank, Unknown, NA
              
   D. Injury at work
     Deaths for "Injury at work" were included on the 1993 public-use data tapes for the first
     time.  These data were obtained from the following item that appears on the U.S. Standard
     Certificate of Death:
            o    (Item 30c)  INJURY AT WORK? (Yes or No)
          
   E. Report of autopsy
     Beginning with the 1995 data year, mortality data on autopsy are no longer processed by
     NCHS, because of resource constraints.
III. Population bases for computing rates
 The population used for computing death rates (furnished by the U.S. Bureau of the Census)
 represents the population residing in the specified area.  Population estimates used for computing
 rates by age, race, and sex for the United States for 1996 are based on population estimates as of
 July 1, 1996 (6)(available upon request). The estimates are based on demographic analysis and,
 therefore, are not subject to sampling variability.
 Population estimates used for computing death rates by specified Hispanic origin, race for non-
 Hispanic origin, age, and sex for the total of 49 States (excludes Oklahoma) and the District of
 Columbia are as of July 1, 1996 (7)(available upon request).  The estimates for Mexicans, Puerto
 Ricans, Cubans, and Other Hispanics are based on the Current Population Survey (CPS) adjusted to
 resident population control totals and, therefore, are subject to sampling error (see Technical
 Appendix from Vital Statistics of the United States: Mortality, 1994).
 Population estimates used for computing death rates by marital status, age, race, and sex for the
 United States (7) are as of July 1, 1996 and are available upon request. Population estimates used
 for computing death rates by marital status, age, Hispanic origin, race for non-Hispanic origin, and
 sex for the total of 49 States (excludes Oklahoma) and the District of Columbia (7) are as of July 1,
 1996 and are also available upon request.  The population estimates for never married, married,
 widowed, and divorced and for Mexicans, Puerto Ricans, Cubans, and Other Hispanics are based on
 the CPS adjusted to resident population control totals and, therefore, are subject to sampling error
 (see Technical Appendix from Vital Statistics of the United States: Mortality, 1994).
 Population estimates used for computing death rates by educational attainment, age, and sex for
 the total of 45 States and the District of Columbia are presented in table IV of the Technical notes
 of the "Report of Final Mortality Statistics" (8).
 Population estimates for each State, Puerto Rico, Virgin Islands, and Guam, (9-12) (available
 upon request) are based on demographic analysis, and therefore, are not subject to sampling
 variability.
 All population estimates for 1996 are based on the 1990 census level counts that were modified
 by age, race, and sex to be consistent with the U.S. Office of Management and Budget categories
 and historical categories for death data (13).
