Smithboro, IL population, income and ZIP codes

Smithboro village is a very small community in Illinois, with 171 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1248 of 1,462 ranked by population — larger than 14% of them. The median age here is 30 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 Smithboro village earn a median of $27,500 a year, 65% below the national figure of $78,538 and 63% 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 42.5% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Smithboro village is valued at $70,000, 76.9% below the national figure and 61% below the $179,100 peer median, while median gross rent runs not published a month. 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. 94.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

A median age of 30 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 171 residents, a handful of survey responses moves every median on this page. Compare Smithboro village against its county rather than against national figures.

The Census withheld gross rent for Smithboro village 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.
