Scott AFB, IL population, income and ZIP codes

Scott AFB CDP is a small town in Illinois, with 4,195 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #368 of 1,462 ranked by population — larger than 74% of them. The median age here is 26.2 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 Scott AFB CDP earn a median of $91,115 a year, 16% above the national figure of $78,538 and 23% 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 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Scott AFB CDP is valued at not published, while median gross rent runs $1,640 a month, 16.6% above the national figure, or roughly $19,680 across a full year. A household on the local median income would put about 21.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 2.2% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 26.2 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld home value for Scott AFB CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
