Franklin Park, IL population, income and ZIP codes

Franklin Park village is a mid-size town in Illinois, with 18,233 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #139 of 1,462 ranked by population — larger than 90% of them. The median age here is 37 years against 39.1 nationally, a slightly younger 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 Franklin Park village earn a median of $76,009 a year, 3.2% below the national figure of $78,538 and within a couple of points of the $74,244 median for the 698 Illinois cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 13.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Franklin Park village is valued at $261,700, 13.7% below the national figure and 46% above the $179,100 peer median, while median gross rent runs $1,103 a month, 21.6% below the national figure, or roughly $13,236 across a full year. A household on the local median income would put about 17.4% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.1% 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.

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.
