Monroe Center, IL population, income and ZIP codes

Monroe Center village is a very small community in Illinois, with 415 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #993 of 1,462 ranked by population — larger than 32% of them. The median age here is 40.9 years against 39.1 nationally, a slightly older 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 Monroe Center village earn a median of $91,563 a year, 16.6% above the national figure of $78,538 and 23% above 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 2.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Monroe Center village is valued at $148,000, 51.2% below the national figure and 17% below the $179,100 peer median, while median gross rent runs $878 a month, 37.6% below the national figure, or roughly $10,536 across a full year. A household on the local median income would put about 11.5% 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 1.6×, 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. 82.8% 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.
