1964-1966 U.S. National Natality Survey
The study is a collection of data for a sample of live births to married women occurring in calendar years 1964, 1965, and 1966. The survey extends, for statistical purposes, the range of items normally included on the vital records. It provides national estimates of births by characteristics not available from the vital registration system. It also serves as a basis for evaluating the quality of information reported on the vital records. Each data record is composed of information obtained from the birth certificate, and from questionnaires sent to the mother, the physician who delivered the baby, and the medical facility where the baby was born. The survey gathered information on pregnancy history, expectations of having more children, household composition, income, whether this was a first or later marriage, date of first marriage and date of this marriage, whether mother was employed and when during her pregnancy she stopped working, education, and health insurance. One out of 1,000 births were originally selected. This data file contains only the subsample of married mothers. Data were collected primarily by mail from addresses given on the birth certificates. The response rate was 89 percent. The total sample size is 10,395 cases. Weights may be used to reflect U.S. estimates of infant births during the study period.
Note for users of DAAPPP Data Sets #01-B1
DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only. Most of these datasets contain SPSS syntax files that use Job Control Language (JCL) from 1980s versions of SPSS-X. Because the syntax is old, the syntax files require editing to conform to the current syntax standards used by SPSS/Windows or SPSS/Unix. If you require technical assistance in using or editing these syntax files, please contact Sociometrics' Data Support Group at 800.846.3475 or firstname.lastname@example.org.
