The Food Access Research Atlas (formerly the Food Desert Locator) is a mapping tool that allows users to investigate multiple indicators of food store access.
The Food Access Research Atlas (formerly the Food Desert Locator) is a mapping tool that provides a spatial overview of food access indicators by census tract, allowing users to investigate multiple indicators of food store access.
ERS's Food Desert Locator is a mapping tool that presents a spatial overview of where food deserts are located and provides selected characteristics of the populations that live in them.
The Food Environment Atlas is a web-based mapping tool developed by ERS that allows users to compare U.S. counties in terms of their “food environment”—indicators that help determine and reflect a community’s access to affordable, healthy food.
The Food Access Research Atlas interactive guide provides an overview of the Food Access Research Atlas to help users understand its background information and low-income and low access measures.
The Food Access Research Atlas maps food access indicators for census tracts using ½-mile and 1-mile demarcations to the nearest supermarket for urban areas, 10-mile and 20-mile demarcations to the nearest supermarket for rural areas, and vehicle availability for all tracts.
All data included in the Food Access Research Atlas are aggregated into an Excel spreadsheet for easy download. The Documentation section provides complete information on data sources and definitions. Note for GIS users: The Atlas is based on 2010 census tract polygons.
This study uses data from the 1990 and 2000 Census, as well as 5-year average data from the 2005-2009 American Community Survey (ACS), to describe changes in characteristics of the 6,529 food desert census tracts over time, relative to changes in all other tracts.
The Food Access Research Atlas maps census tracts that are both low income (li) and low access (la), as measured by the different distance demarcations.
Food Deserts or Food Swamps? Food desert studies have focused on the lack of access to healthy foods, such as fruit and vegetables or whole grains. The flip side of the problem is an abundance of less healthy foods available from convenience stores and fast food restaurants.
