NATIONAL SURVEY OF FAMILY GROWTH
Description:
The National Survey of Family Growth (NSFG) provides information on childbearing, contraception, and related aspects of maternal and child health. The NSFG is the principal national source of data on trends and group differences in contraceptive use and effectiveness, use of family planning services, the wantedness of births, sexual activity of teenagers, and other factors related to the U.S. birth rate. The data are based on personal in-home interviews with a probability sample of women 15-44 years of age. In Cycles I and II (1973 and 1976), the survey was limited to women who had ever been married or had their own children living with them. In Cycles III, IV and V (1982, 1988 and 1995), all women 15-44 years of age were sampled. The 1990 telephone reinterviews was a follow-up of the 1988 respondents. NICHD support for the study began with the 1982 survey. For the first time, the NSFG will be expanded to include men in 2001.
