According to the California Department of Social Services, thousands of children in California's foster care system require temporary out-of-home care because of parental neglect, abuse, or exploitation. The largest percentages are African American and Latino children. Some stay in foster care for weeks; some for years. The children are of all ages and varying needs. Foster parents provide a supportive and stable family for children who cannot live with their birth parents until family problems are resolved. In most cases, foster parents work with social services staff to reunite the child with birth parents. Foster parents often provide care to many different children.
