According to the CWLA, on any given day, there are more than half a million children in foster care in the U.S., the majority of whom have entered care due to abuse and neglect by their parents. Three‐fourths of them are placed by the government with foster parents who open their homes to care for these vulnerable children and almost one‐fifth are placed in group homes and institutions.
