Description
The National Survey of Family Growth (NSFG) gathers information on pregnancy/birth histories, family formation (including marriage and cohabitation), infertility,use of contraception, and general and reproductive health. The NSFG is designed to be nationally representative of women and men ages 15 to 49 years in the household-based population of the United States. Prior to 2002, the NSFG included only women ages 15 to 44 years. Men ages 15 to 44 years were included in the survey in 2002; the age range was expanded to 15 to 49 years in 2015. The NSFG has been conducted through in-person interviews, with a portion of the more sensitive questions answered privately by self-administration. The interviews are voluntary and confidential.
Population Covered
Since the 2002 survey, men and women ages 15 to 44 years in the household population of the United States, and since 2015, men and women ages 15-49 in this same population.
