Supplemental Nutrition Assistance Program (SNAP) Data System

Note: The Food Environment Atlas contains ERS's most recent and reliable data on food assistance programs, including participants in the SNAP Program. The Supplemental Nutrition Assistance Program (SNAP) Data System is no longer being updated due to inconsistencies and reliability issues in the source data. For details on the underlying data sources, see the Documentation.

This data set provides time-series data on State- and county-level estimates of Supplemental Nutrition Assistance Program (SNAP) participation and benefit levels, combined with area estimates of total population, the number of persons in poverty, and selected socio-demographic characteristics of the population. All data, except program benefit amounts, are for a selected point in time each year; program benefit levels are total benefits issued over the course of a calendar year. The most recent year of full data availability is 2012 for State-level SNAP participation and benefits, 2010 for county-level SNAP participation, and 2010 for county-level SNAP benefits. More recent information for SNAP participation and benefits is available for selected counties.
