1970 U.S. National Fertility Study
Investigators: Norman Ryder & Charles Westoff

This study is the second wave of a three-part fertility study which began with the 1965 National Fertility Study (NFS) (documented as DAAPPP Data Set No. 48-49), and ended with the 1975 NFS (documented as DAAPPP Data Set No. 52). A national probability sample of ever-married women under 45 years of age was interviewed for this study. The data cover contraceptive efficacy, fecundability, attitudes toward abortion, sex roles, and world population issues. Also available are detailed background data on respondents and their spouses (age, education, religion and religiosity, ethnicity, occupation, family income, financial conditions). The microcomputer version of the raw data is an extract of 1,125 cases.

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 socio@socio.com.
