Grantfork, IL population, income and ZIP codes

Grantfork village is a very small community in Illinois, with 468 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #965 of 1,462 ranked by population — larger than 34% of them. The median age here is 36.7 years against 39.1 nationally, a slightly younger 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 Grantfork village earn a median of $103,750 a year, 32.1% above the national figure of $78,538 and 40% above the $74,244 median for the 698 Illinois cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 2.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Grantfork village is valued at $195,500, 35.6% below the national figure and 9% above the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.9×, 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. 98.3% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 468 residents, a handful of survey responses moves every median on this page. Compare Grantfork village against its county rather than against national figures.

The Census withheld gross rent for Grantfork 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.
