Farmington city, IL in context
How this area compares with national benchmarks.
Farmington city is a small town in Illinois, with 1,990 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #507 of 1,462 ranked by population — larger than 65% 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 Farmington city earn a median of $64,313 a year, 18.1% below the national figure of $78,538 and 13% 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 8.5% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Farmington city is valued at $99,300, 67.3% below the national figure and 45% below the $179,100 peer median, while median gross rent runs $877 a month, 37.6% below the national figure, or roughly $10,524 across a full year. A household on the local median income would put about 16.4% 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 1.5×, 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. 69.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
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.
