Holcomb, IL population, income and ZIP codes

Holcomb CDP is a very small community in Illinois, with 175 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1244 of 1,462 ranked by population — larger than 14% of them. The median age here is 55.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Holcomb CDP earn a median of $54,250 a year, 30.9% below the national figure of $78,538 and 27% 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 32.3% 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 Holcomb CDP is valued at $130,500, 57% below the national figure and 27% below the $179,100 peer median, while median gross rent runs $960 a month, 31.7% below the national figure, or roughly $11,520 across a full year. A household on the local median income would put about 21.2% 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 2.4×, 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. 84.6% 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 55.4 puts Holcomb CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 175 residents, a handful of survey responses moves every median on this page. Compare Holcomb CDP against its county rather than against national figures.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
