Geneseo, IL population, income and ZIP codes

Geneseo city is a mid-size town in Illinois, with 6,577 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #294 of 1,462 ranked by population — larger than 79% of them. The median age here is 45.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Geneseo city earn a median of $65,226 a year, 16.9% below the national figure of $78,538 and 12% below the $74,244 median for the 698 Illinois cities we cover. 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 2.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Geneseo city is valued at $196,400, 35.3% below the national figure and 10% above the $179,100 peer median, while median gross rent runs $952 a month, 32.3% below the national figure, or roughly $11,424 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 3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 72.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
