Does placing children in foster care increase their adult criminality

We evaluate the association between foster care placement during childhood and adult criminality. In contrast to previous studies, we allow associations to vary by gender and age at initial placement. We find that foster care predicts higher adult criminality for males first placed during adolescence (ages 13–18). We find no significant association for boys who were placed in foster care before age 13 and no significant association on the adult criminality of girls. These null findings stand in stark contrast to the poor outcomes reported in earlier work concerning the long-run effects of foster care.
