The aim of this study is to compare the rates of household food insecurity and child food insecurity among SNAP-participating and SNAP eligible but not participating households with children under age three years during and immediately following the Great Recession.This paper first analyzes food insecurity trends from 2007 to 2013, separately for household food insecurity and child food insecurity and stratified by participation in SNAP. It subsequently examines the association between SNAP participation and food insecurity over from 2007 to 2013.The analyses for this paper demonstrate that even though SNAP’s association with decreased food insecurity has eroded over time, SNAP participation continued to be correlated with lower rates of household and child food insecurity when compared to “No SNAP” households.
