Plainville, IL population, income and ZIP codes

Plainville village is a very small community in Illinois, with 212 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1194 of 1,462 ranked by population — larger than 18% of them. The median age here is 43 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 Plainville village earn a median of $71,250 a year, 9.3% below the national figure of $78,538 and 4% below 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 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Plainville village is valued at $96,900, 68.1% below the national figure and 46% below the $179,100 peer median, while median gross rent runs $688 a month, 51.1% below the national figure, or roughly $8,256 across a full year. A household on the local median income would put about 11.6% 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 1.4×, 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. 89.2% 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.

With 212 residents, a handful of survey responses moves every median on this page. Compare Plainville 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.
