Subset Of Detail Natality Record, 1986-1987
DSN: CC36.SNATAL86 CC36.SNATAL87 ABSTRACT Subsets of the NCHS Natality Data have been created for use by CDC staff. These subsets contain a few of the key variables from the data file as indicated below. These datasets are catalogued tape files on the CDC-Atlanta mainframe named CC36.SNATALXX , where XX represents the year of interest. These data files are subsets of the Detail Natality data from NCHS. These subsets include the following variables from the detail natality files: Resident Status State of Residence County of Residence City of Residence SMSA Sex of Child Race of Father Race of Mother Race of Child Age of Mother Number of Children Born Alive, Now Living Number of Children Born Alive, Now Dead Number of Children Born Dead Age of Father Birth Weight Plurality Birth Data, Month Birth Data, Day Gestation in Weeks Mother's Education Father's Education Legitimacy Month Pregnancy Prenatal Care Began Mother's Place of Birth Record Weight Origin of Mother Origin of Father Number of Prenatal Visits State of Occurrence No. of Other Terminations Before 20 Weeks No. of Other Terminations After 20 Weeks The Natality data include all births occurring within the U.S. The data are obtained from certificates filed for births occurring in each State. Data were obtained from a 50-percent sample of certificates from 1969-1971. Starting in 1972 all records were included for States that participated in the Vital Statistics Cooperative Program (VSCP). The number of States participating in the VSCP increased from 4 in 1972 to 46 in 1984; beginning in 1985, all States and the District of Columbia participated.RECORD LAYOUT NATALITY SUBSET RECORD -------- ------ ------ DSN=CC36.SNATALXX (XX=YEAR) SUBSET CORRESPONDING COLUMNS ITEM LAYOUT ON THE FULL DATA SET ---- ------- --------------------- RESIDENT STATUS 1 12 STATE OF RESIDENCE 2-3 13-14 COUNTY OF RESIDENCE 4-6 15-17 CITY OF RESIDENCE 7-9 18-20 SMSA 10-12 22-24 SEX OF CHILD 13 35 RACE OF FATHER 14 37 RACE OF MOTHER 15 38 RACE OF CHILD 16 39 AGE OF MOTHER 17-18 41-42 NUMBER OF CHILDREN 19-20 52-53 BORN ALIVE, NOW LIVING NUMBER OF CHILDREN 21-22 54-55 BORN ALIVE, NOW DEAD NUMBER OF CHILDREN BORN 23-24 56-57 DEAD AGE OF FATHER 25-26 69-70 BIRTH WEIGHT 27-30 73-76 PLURALITY 31 81 BIRTH DATA, MONTH 32-33 84-85 BIRTH DATA, DAY 34-35 86-87 GESTATION IN WEEKS 36-37 93-94 MOTHER'S EDUCATION 38-39 98-99 FATHER'S EDUCATION 40-41 103-104 LEGITIMACY 42 107 MONTH PREGNANCY 43 109 PRENATAL CARE BEGIN MOTHER'S PLACE 44-45 138-139 OF BIRTH RECORD WEIGHT 46** 208 ORIGION OF MOTHER 47-48 187-188 ORIGIN OF FATHER 49-50 189-190 NUMBER OF PRENATAL 51-52 140-141 VISITS STATE OF OCCURRENCE 53-54 28-29 NO.OF OTHER TERMINA- 55-56 177-178 TIONS BEFORE 20 WEEKS NO.

FIPS codes not available on the Vital Statistics files prior to 1982. 2) NCHS geographic codes used with 1982-87 data are stored in SAS disk file - CC36.NCHSFIPS.XWALK on the CDC-Atlanta mainframe. This data file has FIPS codes linked with NCHS Vital Statistics codes. The documentation for this file is included in the documentation for the detail natality data. 3) Geographic classification for 1962-69 is based on the 1960 census enumeration. Geographic classification for 1970-81 is based on the 1970 census enumeration. Geographic classification for 1982-87 is based on the 1980 census enumeration.
