Of the more than 400,000 children in foster care on a given day, as many as 24,000 (about 6%) receive Supplemental Security Income (SSI) or other Social Security benefits. Some research suggests that a greater number of children in foster care might be eligible for SSI benefits if this assistance was sought. SSI benefits are available under Title XVI of the Social Security Act for certain disabled children from families with low incomes and minimal assets.
