Food Desert Mapping from the National to the Neighborhood Scale.
Recently I was reading the NERCRD newsletter and on the back they had a brief summary of the Food Desert Mapping you might find interesting I know I did when I took a moment to visit. I could definitely see myself using this site to drill down to more specifics about food spending in my county and region.
ArcGis provides a very detailed zoomable maps on food access and numerous related variables on their website. Go to www.arcgis.com/home and enter the words “food access” in the search box. The first items is a supermarket access map which shows the locations of supermarkets relative to populations living in poverty (the latter is available below a certain scale). One of the links is to the Food Atlas newly prepared by USDA’s Economic Research Service. A direct link to this website, which contains reams of useful data is www.ers.usda.gov/foodatlas/
