Foster care youth are more likely than their peers to become pregnant as teenagers. The National Casey Alumni Study, which surveyed foster care alumni from 23 communities across the US, found the birth rate for girls in foster care was more than double the rate of their peers outside the foster care system. A University of Chicago study of youth transitioning out of foster care in Illinois, Iowa, and Wisconsin found that nearly half of the females had been pregnant by age 19. The Utah Department of Human Services found that girls who had left the foster care system between 1999 and 2004 had a birth rate nearly three times the rate for girls in the general population.
