Columbia city, IL in context

How this area compares with national benchmarks.

Columbia city is a mid-size town in Illinois, with 11,063 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #207 of 1,462 ranked by population — larger than 85% of them. The median age here is 39.9 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Columbia city earn a median of $107,922 a year, 37.4% above the national figure of $78,538 and 45% above the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Columbia city is valued at $290,100, 4.4% below the national figure and 62% above the $179,100 peer median, while median gross rent runs $1,089 a month, 22.5% below the national figure, or roughly $13,068 across a full year. A household on the local median income would put about 12.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 81.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
