The Census Bureau's American Factfinder allows you to create maps from census data. Maps can be created at the city, county or state level. Information on age, race, gender, education, housing and other demographic and economic data can be mapped.
Food environment factors--such as store/restaurant proximity, food prices, food and nutrition assistance programs, and community characteristics--interact to influence food choices and diet quality. The objectives of the Atlas are to assemble statistics on food environment indicators to stimulate research on the determinants of food choices and diet quality, and to provide a spatial overview of a community's ability to access healthy food and its success in doing so.
