Sexual Activity and Contraceptive Use Among Teenagers Aged 15-19 in the United States, 2015-2017.

Monitoring sexual activity and contraceptive use among teenagers aged 15-19 in the United States informs understanding of the risk of pregnancy. By 2018, the U.S. birth rate for teenagers dropped 72% from its peak in 1991 (1), paralleling a decline in the teen pregnancy rate (1,2). While this represents progress toward national goals, these rates are still higher than those in other developed countries (3,4). Using data from the 2002 through 2015-2017 National Survey of Family Growth (NSFG), this report provides trends and national estimates of sexual activity and contraceptive use among teenagers.
