Children of color are disproportionately represented in the United States foster care system. In most states, there are higher proportions of African American/Black and Native American children in foster care than in the general child population. In some states, Hispanic/Latino children are disproportionately represented. Data also vary at the county level, with some counties experiencing more disproportionality than is evident statewide. This Technical Assistance Bulletin presents disproportionality rates for all 50 states.
