The Center on Budget and Policy Priorities (CBPP) houses a data dashboard containing the number of government program participants by state. The Program Participation Data Dashboard was recently updated and contains data for federal programs such as HUD housing assistance, the Earned Income Tax Credit, SNAP, Medicaid/CHIP, SSI, and SSDI. The HUD housing assistance data is current as of 2017 and contains counts for all individuals and households in HUD programs. These include public housing, Section 8 Housing Choice Vouchers, Section 8 Project-Based Rental Assistance, and others. Demographic data are also provided by state, including age, race, gender, and head of household information. The data are downloadable as an Excel spreadsheet.
