About This Product

The National Natality Surveys were conducted over a number of years between 1964 and 1980. The 1968 survey was designed primarily to collect information on pre- and post-natal care received by women and by their newborn infants. Additional information was obtained on certain socioeconomic and demographic characteristics. The initial source of data were certificates of live births. Every 1,000th white legitimate infant and every 500th legitimate non-white infant were sampled and questionnaires mailed to 3,474 mothers. The final response rate was 89%. Values for most missing data were imputed for those who did not respond as well as for an additional 121 births who were selected but not mailed questionnaires. Note for users of DAAPPP Data Sets #01-B1DAAPPP 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 socio@socio.com.
