Calhoun ZIP codes — Calhoun County, Illinois

Calhoun County is a small town in Illinois, with 4,406 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 48.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Calhoun County earn a median of $92,095 a year, 17.3% above the national figure of $78,538. 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 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Calhoun County is valued at $174,000, 42.6% below the national figure, while median gross rent runs $479 a month, 65.9% below the national figure, or roughly $5,748 across a full year. A household on the local median income would put about 6.2% 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 1.9×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 89.1% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
