McCook, IL population, income and ZIP codes

McCook village is a very small community in Illinois, with 299 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1091 of 1,462 ranked by population — larger than 25% of them. The median age here is 31.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 McCook village earn a median of $74,464 a year, 5.2% 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. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in McCook village is valued at $319,000, 5.1% above the national figure and 78% above the $179,100 peer median, while median gross rent runs $1,338 a month, 4.8% below the national figure, or roughly $16,056 across a full year. A household on the local median income would put about 21.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 68.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 299 residents, a handful of survey responses moves every median on this page. Compare McCook village against its county rather than against national figures.
