“What Factors Account for State-to-State Differences in Food Security” describes how States differ in the extent to which their residents are food secure-meaning that they have consistent access to enough food for active, healthy living. The prevalence of food security in a State depends not only on the characteristics of households in the State, such as their income, employment, and household structure, but also on State-level characteristics, such as average wages, cost of housing, levels of participation in food assistance programs, and tax policies. Taken together, an identified set of household-level and State-level factors account for most of the State-State differences in food security.
