Map of the study region in Metro Atlanta area with food desert census-tracts in orange. We identified food deserts by selecting the food desert index with the highest utility in this area from among more than 100 indices. This index marks low-income census tracts where a significant number or share of residents is more than half a mile (urban) or ten miles (rural) from the nearest supermarket as a food desert.
