St. Anne, IL population, income and ZIP codes

St. Anne village is a small town in Illinois, with 1,070 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #682 of 1,462 ranked by population — larger than 53% of them. The median age here is 42.8 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 St. Anne village earn a median of $71,574 a year, 8.9% below the national figure of $78,538 and 4% below 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 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in St. Anne village is valued at $129,500, 57.3% below the national figure and 28% below the $179,100 peer median, while median gross rent runs $882 a month, 37.3% below the national figure, or roughly $10,584 across a full year. A household on the local median income would put about 14.8% 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 1.8×, 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. 70.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
