Excerpts: The Supplemental Nutrition Assistance Program (SNAP) helps eligible individuals with low incomes buy food to feed themselves and their households. SNAP is the largest of the domestic nutrition assistance programs administered by the Food and Nutrition Service (FNS) of the U.S. Department of Agriculture (USDA). The SNAP participation rates presented in this research brief are estimates of the percentage of people eligible for SNAP benefits under Federal income and resource rules who participate in the program. State SNAP participation rate estimates can be used to assess recent program performance and focus efforts to improve access. Vigil and Rahimi (2024) examined national SNAP participation rates and rates for socioeconomic and demographic subgroups. This research brief presents estimates of State SNAP participation rates for fiscal year 2022 and revised rates for fiscal year 2020.
