Each year, CMAP updates the Community Data Snapshots for the region’s 7 counties — Cook, DuPage, Kane, Kendall, Lake, McHenry, and Will — 284 communities, and 77 Chicago community areas. This viewer shows only some of the data available in the snapshots. Please download the full PDF for more detailed data.

The City of Chicago's open data portal lets you find city data, lets you find facts about your neighborhood, lets you create maps and graphs about the city, and lets you freely download the data for your own analysis.
