"Birth rates for teenagers differ sharply among race and Hispanic ethnicity population subgroups. In 2003 the overall rate was highest for Mexican teeangers, 93.2 per 1,000 aged 15-19 years, and lowest for API teenagers, 17.4. In-between were 64.7 for non-Hispanic black teenagers, 60.8 for Puerto Ricans, 53.1 for American Indians, and 27.4 for non-Hispanic white teenagers. Whereas rates have fallen for adolescents in all groups over the 1991-2003 period, the most striking declines are for non-Hispanic black teenagers. Overall, their rate fell 45 percent during this period, but the rate for non-Hispanic black teenagers aged 15-17 years has fallen more than one-half, from 86.1 per 1,000 in 1991 to 38.7 in 2003 (figure 3, table A)State-specific teenage birth rates are discussed later in this report. Teenage pregnancy rates have fallen substantially since 1990, generally mirroring the declines in the teenage birth rates. Pregnancy rates are computed from the sums of live births, induced abortions, and fetal losses. Currently, teenage pregnancy rates are available through 2000, the most recent year for which detailed national abortion estimates are available. The teenage pregnancy rate in 2000 was 84.5 per 1,000 females aged 15-19 years, the lowest rate reported since 1976, when the Centers for Disease Control and Prevention, NCHS series of national estimates first became available. The rate has dropped 27 percent since its 1990 peak (116.3). The decline in the pregnancy rate during 1990-2000 is reflected in declines in live births and induced abortions, with larger declines reported for abortions."
