What Are Food Deserts?

Food deserts are areas where residents have limited access to affordable, nutritious food. The USDA defines low food access as living more than 1 mile from a supermarket in urban areas, or more than 10 miles in rural areas.

This site uses data from the USDA Economic Research Service Food Access Research Atlas, combined with Census Bureau demographic data and SNAP participation statistics.
