Food Desert Locator

That's desert (empty wasteland), not dessert (yummy goodness). Yes, there are many, many food deserts in the United States--neighborhoods with high concentrations of low-income people who are far from a grocery store. At this site you can access an interactive map of the United States that reveals our many food deserts by state and local area down to the census tract level. A food desert is defined as a census tract in which at least one-third of the residents live more than one mile (in an urban area) or more than 10 miles (in a rural area) from a supermarket or large grocery store.
