Deer Park, IL population, income and ZIP codes

Deer Park village is a small town in Illinois, with 3,711 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #397 of 1,462 ranked by population — larger than 72% of them. The median age here is 43.7 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 Deer Park village earn a median of $160,750 a year, 104.7% above the national figure of $78,538 and 117% above 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 1.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Deer Park village is valued at $636,200, 109.7% above the national figure and 255% above the $179,100 peer median, while median gross rent runs $2,389 a month, 69.9% above the national figure, or roughly $28,668 across a full year. A household on the local median income would put about 17.8% 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×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 78.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
