Where the churches are in Illinois
The cities with the most churches on the map are Chicago (390), East St. Louis (16), East Saint Louis (11), Alorton (8), Brooklyn (2). The largest of them, Chicago, holds about 90 percent of the 433 churches counted for Illinois, which is why a smaller town can look empty here when a church is simply not yet on the map.
What this count does and does not tell you
The 433 churches counted for Illinois are the places that volunteers have tagged as churches on OpenStreetMap, as of 2026-08-15. It is a map, not a ranking, and it says nothing about how alive any one congregation is. House churches, new plants and small congregations are often missing. If your church is not listed, you can add it, and a believer who gathers people near you can start a group on this page.
