Excluding English and Spanish, Polish is the most common language spoken at home in Illinois. But when Illinois is broken up into smaller regions, dozens of other languages show up as the most common after excluding English and Spanish.
The regions on this map are from the U.S. Census Bureau's Public Use Microdata Areas. Each region has about 100,000-200,000 residents.
The language data are from the Census Bureau's 2018 American Community Survey, which collapses over 1300 languages and language groups into about 130 languages and language groups for the Public Use Microdata Samples used for this map.
