The National Survey of Family Growth, or NSFG, was conducted in 1973, 1976, 1982, 1988, and 1995. During that time, it has been a survey of women 15 to 44 years of age, designed to produce estimates of sexual activity, marriage and divorce, infertility, contraceptive use, and use of health services that will shed light on birth and pregnancy rates in the US. The survey has been designed to produce estimates for subgroups by age, region, race, education, income and other variables. In the 2001 NSFG (also known as Cycle 6), the NSFG will include a national sample of men 15 to 49 years of age in addition to a national sample of women. HIV funding is being used specifically for the sample of males and for the operations necessary to obtain large samples of black, Hispanic, and 15 to 24-year-old men and women. In addition, the content of the survey is being upgraded to include more HIV-related data, including anal intercourse as well as vaginal intercourse, same-gender sexual activity, condom use for disease prevention, risk behaviors including substance use, exchanging money or drugs for sex, non-voluntary sex, and sexually transmitted disease history. Because most of this HIV-related content is very sensitive for the general population, much of it is administered with Audio Computer-Assisted Self-Interviewing (Audio CASI).
The survey schedule is also being accelerated. Cycle 6 is scheduled for 2001, Cycle 7, for 2004, and Cycle 8, for 2007.
