Forest Park, IL population, income and ZIP codes

Forest Park village is a mid-size town in Illinois, with 14,000 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #177 of 1,462 ranked by population — larger than 87% of them. The median age here is 40 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 Forest Park village earn a median of $81,323 a year, 3.5% above the national figure of $78,538 and 10% 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 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Forest Park village is valued at $293,800, 3.2% below the national figure and 64% above the $179,100 peer median, while median gross rent runs $1,352 a month, 3.8% below the national figure, or roughly $16,224 across a full year. A household on the local median income would put about 20% 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 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 53.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.
