Irwin, IL population, income and ZIP codes

Irwin village is a very small community in Illinois, with 60 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1392 of 1,462 ranked by population — larger than 4% of them. The median age here is 38 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Irwin village earn a median of $87,083 a year, 10.9% above the national figure of $78,538 and 17% above 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 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Irwin village is valued at $144,600, 52.3% below the national figure and 19% below the $179,100 peer median, while median gross rent runs $1,125 a month, 20% below the national figure, or roughly $13,500 across a full year. A household on the local median income would put about 15.5% 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 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. 84% 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.

With 60 residents, a handful of survey responses moves every median on this page. Compare Irwin village against its county rather than against national figures.

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.
