According to preliminary data, the birth rate among adolescents aged 15-19 years increased to 42.5 births per 1,000 females in 2007, from 41.9 per 1,000 the previous year. This was the first increase since the most recent peak in 1991 (61.8 births per 1,000), but still represents an overall decrease of 31 percent since that year. The birth rate among adolescents aged 10-14 years decreased to 0.6 per 1,000, which represents a decline of more than 50 percent since 1991. Teenage birth rates were highest among older adolescents, aged 18- 19 years, at 73.9 per 1,000.
Teenage birth rates have historically varied considerably by race/ethnicity. Among adolescents aged 15-19 years, Asian/Pacific Islanders had the lowest birth rate in 2006 (17.3 per 1,000), followed by non-Hispanic Whites (27.2 per 1,000). Hispanic females had the highest birth rate in this age group (81.7 per 1,000), and also the lowest percentage decline since 1991 (21.9 percent). Non-Hispanic Black females had the second highest birth rate among those aged 15-19 years (64.3 per 1,000), but the highest percentage decline since 1991 (45.8 percent).
Among adolescents aged 10-14 years, non- Hispanic Black females had the highest birth rate (1.5 per 1,000), followed by Hispanic females (1.2 per 1,000) and American Indian/Alaska Native females (0.9 per 1,000). Non-Hispanic White and Asian/Pacific Islander females had the lowest birth rates among those aged 10-14 years (0.2 per 1,000).
