The National Survey of Family Growth (NSFG) gathers information on pregnancies and births, marriage and cohabitation, infertility, use of contraception, family life, and general and reproductive health. Restricted-use files include contextual data, restricted-use analytic variables, paradata, and interviewer observation data. Geographic information can be used to link NSFG to external data files. Estimates cannot be made for specific geographic areas. Contents of restricted-use files varies over time.
