Food Desert–Related GIS Maps of Delaware

Food Desert Defined

There are many ways to define "food deserts" and many ways to measure food store and farmers market access for individuals and for neighborhoods. Most measures and definitions take into account at least some of the following indicators of access:

  • Accessibility to sources of healthy food, as measured by distance to a grocery store and farmers market, or by the number of stores and farmers markets in an area.
  • Individual-level resources that may affect accessibility, such as family income or vehicle availability.
  • Neighborhood-level indicators of resources, such as the average income of the neighborhood.

Map Data Sources

The food desert regions shown on the maps below are defined by the USDA Food Access Research Atlas using their 2011 data set and two alternative definitions of food deserts:

  • USDA Definition 1: 0.5 mi. urban, 10 mi. rural
  • USDA Definition 2: 1 mi. urban, 10 mi. rural 

The grocery store and farmers market map dots were created from the Institute for Public Administration's 2014 data set. The Kent County maps were updated again in 2016 to reflect new grocery store and farmers market data.

When viewing/using these PDF maps, keep in mind that the specific grocery store/farmers market markers are based on more recent data than the shaded food desert regions.
