Illinois Ancestry and Population Demographic Data

On this page, you'll find details on the largest ethnic ancestries in Illinois, with links to ancestry pages to research more data.

Below, we'll show you the full list of different ancestries reported in Illinois for the past 5 years. These start from the latest figures from the Census Bureau for 2019, back to 2015.

To make the surfacing of this data easier, we've listed it in descending order based on the most recent year of data available, which means that past years may not be in the correct descending order.

All ancestry labels below are the grouping terms used by the U.S. Census Bureau and are not labels that Name Census has provided.
