Methodology Notes

Pregnancies include live births, miscarriages, or induced abortions.

Females are considered to have experienced pregnancy despite use of a reversible method if there was continuous method use (in 12-month intervals) and they became pregnant during a month of use of one or more of the following methods: birth control pills, condom (rubber), diaphragm, foam/jelly/cream, cervical cap, suppository, insert, TodayTM sponge, female condom (vaginal pouch), IUD, coil, loop, Norplant, Depo-provera, injectables, withdrawal (pulling out), rhythm/natural family planning, or emergency contraception/morning-after pill.

NSFG data are adjusted for underreporting of abortions using data from The Guttmacher Institute’s Abortion Patient Survey. Detailed information on adjustment procedure, contraceptive methods and failure rates have been published by The Guttmacher Institute.
