Clarendon Hills, IL population, income and ZIP codes

Clarendon Hills village is a mid-size town in Illinois, with 8,642 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #252 of 1,462 ranked by population — larger than 82% of them. The median age here is 41.4 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Clarendon Hills village earn a median of $125,826 a year, 60.2% above the national figure of $78,538 and 69% 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 7.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Clarendon Hills village is valued at $595,500, 96.3% above the national figure and 232% above the $179,100 peer median, while median gross rent runs $1,124 a month, 20.1% below the national figure, or roughly $13,488 across a full year. A household on the local median income would put about 10.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 82.9% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
