2010 Census Introduction

Census 125

On August 4, 2011, the U.S. Census Bureau released Summary File 1 (SF1) for Illinois. This was the fourth release of 2010 Census data following earlier releases of population counts used for apportionment and redistricting. Summary File 1 provides the most detailed data from Census 2010, including new housing and home ownership data, population counts for race and ethnicity (including detailed race and Hispanic or Latino origin groups), expanded data by age and sex, and relationship of household members to householder.

Selected 2010 SF1 results for CMAP Counties, County Subdivisions(Townships), Places and Chicago Community Areas (CCA's) can be found here (Excel 287 Kb). A glossary of terms is also available. Regional data tables available for download include households by type, average household size and average family size, as well as housing unit counts, tenure and vacancy rates. See CMAP Policy Updates blog for detailed analysis.

Visit the Census 2010 website for an introduction to demographic profiles. Demographic profile data can be found by navigating to the Census Bureau's AmericanFactFinder website. Follow these additional steps below to find data for your home town.
