Fairmont CDP, IL in context
How this area compares with national benchmarks.
Fairmont CDP is a small town in Illinois, with 2,409 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #472 of 1,462 ranked by population — larger than 67% of them. The median age here is 31.3 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 Fairmont CDP earn a median of $59,244 a year, 24.6% below the national figure of $78,538 and 20% below 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 17% of residents here, above the 12.4% national rate.
The typical owner-occupied home in Fairmont CDP is valued at $147,400, 51.4% below the national figure and 18% below the $179,100 peer median, while median gross rent runs $1,372 a month, 2.4% below the national figure, or roughly $16,464 across a full year. A household on the local median income would put about 27.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 63% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
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.
