Seymour, IL population, income and ZIP codes

Seymour CDP is a very small community in Illinois, with 333 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1055 of 1,462 ranked by population — larger than 27% of them. The median age here is 29.3 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 Seymour CDP earn a median of not published a year. 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 15.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Seymour CDP is valued at $135,500, 55.3% below the national figure and 24% below the $179,100 peer median, while median gross rent runs not published a month. 59.6% 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.

A median age of 29.3 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. With 333 residents, a handful of survey responses moves every median on this page. Compare Seymour CDP against its county rather than against national figures.

The Census withheld household income, gross rent for Seymour 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.
