Provides general characteristics of US census tracts in the context of access to food. Metrics include Individual-level resources that may affect accessibility, such as family income or vehicle availability, and neighborhood-level indicators of resources, such as the average income of the neighborhood and the availability of public transportation. The criteria for identifying a census tract as low income are from the Department of Treasury’s New Markets Tax Credit (NMTC) program, which defines a low-income census tract as any tract where: the tract’s poverty rate is 20 percent or greater; or the tract’s median family income is less than or equal to 80 percent of the statewide median family income; or the tract is in a metropolitan area and has a median family income less than or equal to 80 percent of the metropolitan area's median family income. Low access to healthy food is defined as being far from a supermarket, supercenter, or large grocery store.
