Justice Map is an online visualization tool that lets users map race and income data at the neighborhood, county, state, or federal levels. The tool, sponsored by the Sunlight Foundation and energy activism nonprofit the Energy Justice Network, is the most granular tool of its kind. Its creator hopes it will help journalists and activists create maps for publication and advocacy, and help map designers incorporate race and income layers into their maps for other purposes. The data comes from the 2010 Census and the 2007-2011 American Community Survey.
