Kost and her colleagues also found declines in teen pregnancy rates across all racial and ethnic groups and all 50 states. But racial and geographic disparities remain. The teen pregnancy rate declined between 1990 and 2010 by more than 50 percent among white, black and Hispanic teens. However, pregnancy rates for black and Hispanic teens remain twice as high as the rate for white teens. In 2010, the rate among black teens was 99.5 pregnancies per 1,000 teens, the rate among Hispanic teens was 83.5 per 1,000 and the rate among white teens was 37.8 per 1,000.
