USDA Low Food Access

Through Food Access Research Atlas, the United States Department of Agriculture (USDA) provides a spatial view of food access data for low-income and other census tracts with indicators based on income, ethnicity, and other demographic information for census tracts, along with different measures for supermarket accessibility. Aggregated data is available in the public domain and is available here:

In this visualization, we have enhanced the food atlas by providing a more detailed map that analyzes more census data and provides a more analytical perspective to allow the user to understand the relationship between food deserts and key demographic census indicators on the census tract level. There are more than 72,000 census tracts in the United States and each tract is comprised of 5,000-8,000 people.
