Healthy Food Access Resources

This application was developed through a partnership with the Master of Geospatial Information Science and Technology (MGIST) program at North Carolina State University and NCAH. There are two main purposes for this application. First, it is to show the locations of SNAP retailers in North Carolina and provide the store name and address. Secondly, through geospatial analysis of census data, the application helps identify disparities in SNAP coverage in North Carolina legislative districts (Congressional, Senate, and House).

North Carolina Supplemental Nutrition Assistance Program (SNAP) Coverage Application

These maps show food access in North Carolina as a state, and in 5 NC cities (Fayetteville, Goldsboro, Lexington, Raleigh, Winston-Salem). Please note that the data used does not represent food deserts, but areas in which residents are low income and where there are low supermarket sales and high rates of diet-related deaths.

City Maps


  • There are large swaths of the state where residents are suffering with diet-related disease and can’t easily access a venue to purchase healthy foods. In addition to the cites, we see large areas in need in many rural areas. (Map 6)
  • Neighborhoods with greater than average supermarket sales relative to total population could indicate more people are buying groceries in these communities than the number of people who live there. This could mean people are traveling from outside the area to shop there. (Map 2)
  • There are few or no supermarkets in areas that are low income and also have low sales. Since income is lower in these areas, people living there are less able to afford to travel to the areas where supermarkets are concentrated. (Map 4)
  • Summary


  • Total state population (2014): 9,750,405
