Prairie Grove, IL population, income and ZIP codes

Prairie Grove village is a small town in Illinois, with 1,992 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #506 of 1,462 ranked by population — larger than 65% of them. The median age here is 41.7 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 Prairie Grove village earn a median of $138,229 a year, 76% above the national figure of $78,538 and 86% above 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 4.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Prairie Grove village is valued at $439,100, 44.7% above the national figure and 145% above the $179,100 peer median, while median gross rent runs $2,110 a month, 50.1% above the national figure, or roughly $25,320 across a full year. A household on the local median income would put about 18.3% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 92.4% 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. 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.
