Food Desert Locator from the USDA. GoodFood World Staff, May 4th, 2011. The official definition of a food desert is a low income census tract where at least a third of the residents are a mile from a supermarket or large grocery store.
A desert is a very dry area of land where few plants and animals can live. If you find yourself stranded in the middle of the desert, you'll have no company except for the occasional lizard or scorpion. Desert comes from the Latin desertus, for abandoned or lying in waste. This can refer to a vast sandy area without vegetation, or any empty, lifeless expanse. As a verb, it means to leave someone or something. A soldier who runs away from the army is called a deserter.
