Coal City, IL population, income and ZIP codes

Coal City village is a mid-size town in Illinois, with 5,145 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #331 of 1,462 ranked by population — larger than 77% of them. The median age here is 42.3 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 Coal City village earn a median of $73,030 a year, 7% below the national figure of $78,538 and within a couple of points of the $74,244 median for the 698 Illinois cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 4.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Coal City village is valued at $211,600, 30.3% below the national figure and 18% above the $179,100 peer median, while median gross rent runs $1,064 a month, 24.3% below the national figure, or roughly $12,768 across a full year. A household on the local median income would put about 17.5% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 80.7% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
