The NSFG is a periodic survey initiated to provide current information on fertility and infertility, family planning, childbearing, contraceptive practice, and other aspects of maternal and child health and to gauge the effects of these processes on population growth. The NSFG Cycle 6 interviews, conducted in 2002, covered the respondent’s pregnancy history, past and current use of contraception, ability to bear children, use of medical services for family planning, infertility, prenatal care, marital history, and associated cohabiting unions. Data on occupation and labor force participation and on a wide range of social, economic, and demographic characteristics are also presented. In addition, Cycle 6 adds detailed questions on HIV risk behaviors and fatherhood and father involvement.
