Ste. Marie, IL population, income and ZIP codes

Ste. Marie village is a very small community in Illinois, with 266 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1125 of 1,462 ranked by population — larger than 23% of them. The median age here is 28.5 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 Ste. Marie village earn a median of $80,417 a year, 2.4% above the national figure of $78,538 and 8% above 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 8.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Ste. Marie village is valued at $103,900, 65.8% below the national figure and 42% below the $179,100 peer median, while median gross rent runs $263 a month, 81.3% below the national figure, or roughly $3,156 across a full year. A household on the local median income would put about 3.9% 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 1.3×, 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. 90.3% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 28.5 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 266 residents, a handful of survey responses moves every median on this page. Compare Ste. Marie 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.
