Mendon village, IL in context

How this area compares with national benchmarks.

Mendon village is a small town in Illinois, with 1,131 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #662 of 1,462 ranked by population — larger than 54% of them. The median age here is 37.2 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 Mendon village earn a median of $62,778 a year, 20.1% below the national figure of $78,538 and 15% below the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 13.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mendon village is valued at $108,500, 64.2% below the national figure and 39% below the $179,100 peer median, while median gross rent runs $661 a month, 53% below the national figure, or roughly $7,932 across a full year. A household on the local median income would put about 12.6% 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. 77.5% 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.

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.
