The largest of Illinois's 945 recorded places, ranked by population — 11,340,428 people across the state's towns and cities.
The essentials
Chicago is the largest place we record in Illinois, with 2,664,452 residents. The three largest together hold 27% of the 11,340,428 people counted across the state's recorded towns and cities. That total sums listed places rather than measuring the state itself, so treat it as coverage, never as an official population.

Figures are the latest available in
GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are
UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such.
