2010 Census Maps

April 22nd, 2011

The U.S. Census Bureau has placed 2010 Census maps on the Web.  The data may be particularly helpful for public library districts that will have to compare their district boundaries to census geography to arrive at their population figure for annual Illinois State Library Public Library Per Capita grants.  There are four types of 2010 census maps, and they are all in PDF format at the following URL’s:

Census Tract Reference Maps – http://www.census.gov/geo/www/maps/pl10_map_suite/tract.html
County Block Maps – http://www.census.gov/geo/www/maps/pl10_map_suite/cou_block.html
Voting District/State Legislative District Reference Maps – http://www.census.gov/geo/www/maps/pl10_map_suite/vtd_sld.html
School District Reference Maps – http://www.census.gov/geo/www/maps/pl10_map_suite/sch_dist.html

For each map select the state of Illinois, then select the county, then select the “000” or “001” index.  Each type of geography has corresponding data in the new American FactFinder2 (http://factfinder2.census.gov), including school districts.  Learn how to find the population statistic of a given Census Tract using American Factfinder2 at http://www.cubitplanning.com/data/american-fact-finder-census-tracts

The State Library does not have and will not have paper versions of these maps.

Additionally, 2009 Illinois county taxing district maps are available in PDF format at:


Select your county, then select the library district map.  The 2009 maps are the most recent maps available.  New county taxing district maps will be available later this year.

If you have any questions or want more information about these maps, contact the ISL Map Room at 217/782-5823 or e-mail islmap@ilsos.net.
