States were given the option to eliminate documentation for some eligibility criteria, including birth dates, state residency, and household composition. 60 For other criteria, including income and citizenship, verification was required. States, however, could access existing administrative data for verification. A federal database was created for this purpose, featuring data from the Social Security Administration, the Internal Revenue Service (IRS), and the Department of Homeland Security. States could also draw on their own sources. Nearly all states use their wage and unemployment compensation data to verify status. About half of states use vital data services and a smaller fraction draw on records from the Department of Motor Vehicles.
