Mount Clare, IL population, income and ZIP codes

Mount Clare village is a very small community in Illinois, with 322 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1068 of 1,462 ranked by population — larger than 26% of them. The median age here is 56.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Mount Clare village earn a median of $66,125 a year, 15.8% below the national figure of $78,538 and 11% below the $74,244 median for the 698 Illinois cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 16.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mount Clare village is valued at $111,100, 63.4% below the national figure and 38% below the $179,100 peer median, while median gross rent runs $569 a month, 59.5% below the national figure, or roughly $6,828 across a full year. A household on the local median income would put about 10.3% 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. 75.2% 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.

A median age of 56.7 puts Mount Clare village well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 322 residents, a handful of survey responses moves every median on this page. Compare Mount Clare village against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
