"Data USA is an aggregate visualization engine with public datasets from many different sources including those from official US departments as well as educational institutions."
- Presents a spatial overview of food access indicators for low-income and other census tracts using different measures of supermarket accessibility;
- Provides food access data for populations within census tracts; and
- Offers census-tract-level data on food access that can be downloaded for community planning or research purposes.
"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."
