State social service agencies are responsible for determining eligibility for public benefits like the Supplemental Nutrition Assistance Program (SNAP or food stamps), Temporary Aid for Needy Families (TANF), Medicaid, state-based General Assistance, and other benefits. These programs cover over 60 million people nationwide, many of whom may not be included on driver's license databases or other lists. States manage these programs using computerized constituent databases, which typically include clients of several different programs.
