National Survey of Family Growth - Wave 5 (1995) Pregnancy File




These surveys were based on personal interviews conducted in the homes of a national sample of women 15-44 years of age in the civilian, non-institutionalized population of the United States. The main purpose of the survey was to provide reliable national data on marriage, divorce, contraception, infertility, and the health of women and infants in the United States. The survey contains key religion variables that may relate to these goals.

The pregnancy file uses each pregnancy mentioned by a respondent as the unit of analysis and contains detailed pregnancy histories and wantedness of pregnancies, as well as selected respondent characteristics. The recodes were created to simpify analyses, and are provided for key variables in virtually every topic.

Using the common identification number (CASEID), and the pregnancy number (PREGORDR), the interval and respondent files can be merged to produce a file containing both respondent information and pregnancy information. The resulting file can be either respondent-based (up to 10,847 records) or interval-based (up to 21,332 records).

The ARDA has added four additional variables to the original data set to enhance the users' experience on our site.
