Fairbury city, IL in context

How this area compares with national benchmarks.

Fairbury city is a small town in Illinois, with 3,683 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #398 of 1,462 ranked by population — larger than 72% of them. The median age here is 39.5 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 Fairbury city earn a median of $65,215 a year, 17% below the national figure of $78,538 and 12% below the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Fairbury city is valued at $155,900, 48.6% below the national figure and 13% below the $179,100 peer median, while median gross rent runs $750 a month, 46.7% below the national figure, or roughly $9,000 across a full year. A household on the local median income would put about 13.8% 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 2.4×, 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. 67.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
