News release: “The online Food Desert Locator, developed by the U.S. Department of Agriculture’s (USDA) Economic Research Service (ERS), is a tool that can be used to assist efforts to expand the availability of nutritious food in food deserts, or low-income communities that lack ready access to healthy food. Expanding the availability of nutritious food is part of First Lady Michele Obama’s Let’s Move! initiative to address the epidemic of childhood obesity…A food desert is a low-income census tract where either a substantial number or share of residents has low access to a supermarket or large grocery store. “Low income” tracts are defined as those where at least 20 percent of the people have income at or below the federal poverty levels for family size, or where median family income for the tract is at or below 80 percent of the surrounding area’s median family income. Tracts qualify as “low access” tracts if at least 500 persons or 33 percent of their population live more than a mile from a supermarket or large grocery store (for rural census tracts, the distance is more than 10 miles). This definition was developed by a working group comprised of members from the departments of Treasury, Health and Human Services, and USDA, which is partnering to expand the availability of nutritious food.”
