Highland Park, IL population, income and ZIP codes

Highland Park city is a small city in Illinois, with 30,229 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #65 of 1,462 ranked by population — larger than 95% of them. The median age here is 46 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Highland Park city earn a median of $161,875 a year, 106.1% above the national figure of $78,538 and 118% 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 3.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Highland Park city is valued at $594,400, 95.9% above the national figure and 232% above the $179,100 peer median, while median gross rent runs $1,903 a month, 35.3% above the national figure, or roughly $22,836 across a full year. A household on the local median income would put about 14.1% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 83.7% 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.

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.
