Feeding America recently released Map the Meal Gap 2013 which provides estimates of food insecurity for every county and congressional district in the United States. The report also provides data and analysis on the percentage of the food insecure population that likely qualify for SNAP (i.e. food stamps) and other federal food assistance programs, along with the percentage of those who do not qualify for federal programs. Information on the average cost per meal in each county is also provided.
An interactive map is included with the report along with a variety of additional resources.
