From the abstract:
The Supplemental Nutrition Assistance Program (SNAP) aims to reduce hunger and food insecurity by supplementing the purchasing power of low-income families. This analysis explores the adequacy of SNAP benefits by comparing the maximum SNAP benefit per meal with the average cost of a low-cost meal in the U.S., adjusting for geographic variations in food prices across counties in the 48 contiguous states and Washington, DC. We find that average cost of a low-income meal is $2.36, 27 percent higher than the SNAP maximum benefit per meal of $1.86, which takes into account the maximum benefit available to households of varying sizes. The SNAP per meal benefit does not cover the cost of a low-income meal in 99 percent of US continental counties and the District of Columbia.
