United States Department of Agriculture Economic Research Service’s Food Access Research Atlas maps census tracts that are considered to be both low income and low access. The Atlas provides different ways to understand characteristics that can contribute to food deserts, including income level, distance to supermarkets, and vehicle access. The low access and distance measure extracted from the Food Access Research Atlas, and displayed on the Maryland Food System Map, is low income and low access measured at ½ mile and 10 miles. The Food Access Research Atlas defines this measure as being a low-income census tract with at least 500 people or 33 percent of the population living more than ½ mile (urban areas) or more than 10 miles (rural areas) from the nearest supermarket. A low-income census tract is defined as a having either a poverty rate of 42 percent or more, or a median family income less than 80 percent of the State-wide median family income; or a tract in a metropolitan area with a median family income less than 80 percent of the surrounding metropolitan area medium family income. A census tract is urban if its geographic centroid is in an area with more than 2,500 people. All other tracts are rural.
