Karnak, IL population, income and ZIP codes

Karnak village is a very small community in Illinois, with 507 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #940 of 1,462 ranked by population — larger than 35% of them. The median age here is 42.2 years against 39.1 nationally, a slightly older 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 Karnak village earn a median of $41,458 a year, 47.2% below the national figure of $78,538 and 44% below the $74,244 median for the 698 Illinois cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 30.4% 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 Karnak village is valued at $66,700, 78% below the national figure and 63% below the $179,100 peer median, while median gross rent runs $708 a month, 49.6% below the national figure, or roughly $8,496 across a full year. A household on the local median income would put about 20.5% 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 1.6×, 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. 77.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 507 residents, a handful of survey responses moves every median on this page. Compare Karnak village against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
