St. Francisville, IL population, income and ZIP codes

St. Francisville city is a very small community in Illinois, with 578 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #890 of 1,462 ranked by population — larger than 39% of them. The median age here is 34.5 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 St. Francisville city earn a median of $64,583 a year, 17.8% below the national figure of $78,538 and 13% below the $74,244 median for the 698 Illinois cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 16.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in St. Francisville city is valued at $58,400, 80.8% below the national figure and 67% below the $179,100 peer median, while median gross rent runs $943 a month, 32.9% below the national figure, or roughly $11,316 across a full year. A household on the local median income would put about 17.5% 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 0.9×, 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. 78.2% 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.
