Winthrop Harbor, IL population, income and ZIP codes

Winthrop Harbor village is a mid-size town in Illinois, with 6,663 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #293 of 1,462 ranked by population — larger than 80% of them. The median age here is 51.6 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 Winthrop Harbor village earn a median of $94,221 a year, 20% above the national figure of $78,538 and 27% above 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 7.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Winthrop Harbor village is valued at $238,800, 21.3% below the national figure and 33% above the $179,100 peer median, while median gross rent runs $1,262 a month, 10.2% below the national figure, or roughly $15,144 across a full year. A household on the local median income would put about 16.1% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 85.6% 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 51.6 puts Winthrop Harbor village 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.

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.
