This interactive map tool and associated data set lets users map low-income areas having high-density populations that lack good access to nutritious food (“food deserts”). Census tract-level statistics for these areas may also be viewed. Satellite imagery provides an optional background in the map viewer. SEDAC’s U.S. Census Grids data are used as a key source for the tool.
A typically higher standard of living in urban areas compared to rural ones does not rule out striking disparities within cities. SEDAC data from its Global Poverty Mapping Project is used as the basis for this map. Map 1.2, illustration for Chapter 1--Density, The World Development Report Online 2009.
