Description: These data were prepared by USDA REE-ERS to analyze various populations and their access to food at Supplemental Nutrition Assistance Program (SNAP) authorized retailers. This data set measures access as straight-line distance from stores. The area outlines are from US Census Bureau TIGER data. Limited access to supermarkets, supercenters, grocery stores, or other sources of healthy and affordable food may make it harder for some people to eat a healthy diet in this country. There are many ways to measure food store access for individuals and for neighborhoods, and many ways to define which areas are low-income and low access—neighborhoods that lack healthy food sources. Most measures and definitions consider at least some of the following indicators of access:Accessibility to sources of healthy food, as measured by distance to a store or by the number of stores in an area;Individual-level resources that may affect accessibility, such as family income or vehicle availability; andNeighborhood-level indicators of resources, such as the average income of the neighborhood and the availability of public transportation.In the Food Access Research Atlas, several indicators are available to measure food access along these dimensions. For example, users can choose alternative distance markers to measure low access in a neighborhood, such as the number and share of people more than one-half mile to a supermarket or 1 mile to a supermarket. Users can also view other census-tract-level characteristics that provide context on food access in neighborhoods, such as whether the tract has a high percentage of households far from supermarkets and without vehicles, individuals with low income, or people residing in group quarters.
