1975 U.S. National Fertility Study
Investigators: Charles Westoff & Norman Ryder

This is the third in a series of studies begun in 1965 and continued in 1970 (documented as DAAPPP Data Set Nos. 48-49 and 50-51, respectively). Unlike its predecessors, this study was longitudinal in its design. The data collected were from a national probability sample of once-married and currently married women who were white, married fewer than 25 years and before the age of 25, and whose husbands were also once-married. Reinterview data were also collected from continuously married respondents to the 1970 survey (an interval of approximately five years). The sample included 1,042 new respondents, together with 2,361 women reinterviewed, for a total of 3,403 respondents. In addition to the scope of previous studies, the present data includes new information on those reinterviewed, such as success in fertility forecasting. This dataset is an extract of 1,134 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.
