Nearly 625,000 adolescent girls became pregnant in the United States in 2010; 614,000 of
these pregnancies were among women 15-19 and 11,000 were aged 14 and younger, 31.3%
resulted in live births, 26% were terminated, and 15% resulted in miscarriage or stillbirth.
The teenage birth rate in the U.S. was 3.4% in 2010, the lowest it has been since 1946;
however, this rate remains substantially higher than the adolescent birth rates in most other
developed countries (e.g., the teen birth rate from 2000–2009 was 0.49% in Japan, 0.98%
in Germany, and 1.42% in Canada). More than 40% of adolescent girls have been pregnant
by the age of 20 years and 82% of adolescent pregnancies are unintended. In the U.S., Black
and Hispanic adolescents are more likely than White adolescents to become pregnant.
