For every 1,000 black boys in the United States, 29 of them are fathers, compared to 14 per 1,000 white boys.[6] The rate of teen fatherhood declined 36% between 1991 and 2010, from 25 to 16 per 1,000 males aged 15–19. This decline was more substantial among blacks than among whites (50% vs. 26%) and about half of the rate among teen girls.[6] Nearly 80% of teenage fathers do not marry the teenage mother of their child.[15] Teenage fathers have 10-15% lower annual earnings than teenagers who do not father children.[15]
