Cumberland ZIP codes — Cumberland County, Illinois

Cumberland County is a mid-size town in Illinois, with 10,378 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. 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 Cumberland County earn a median of $69,826 a year, 11.1% below the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 9.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Cumberland County is valued at $117,700, 61.2% below the national figure, while median gross rent runs $756 a month, 46.2% below the national figure, or roughly $9,072 across a full year. A household on the local median income would put about 13% 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 1.7×, 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. 83.5% 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
