Summary
These surveys were based on personal interviews completed with 22,682 respondents. The main purpose of the NSFG surveys have been 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 2006-2010 NSFG survey represents a shift from periodic surveys to continues interviewing, with interviews being conducted 48 weeks of every year for 4 years. This public use data file contains all interviews conducted from June 2006-June 2010.

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.

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 or interval-based. The ARDA used the interval-based format for the data set.
