Olympia Fields, IL population, income and ZIP codes

Olympia Fields village is a small town in Illinois, with 4,636 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #346 of 1,462 ranked by population — larger than 76% of them. The median age here is 45 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 Olympia Fields village earn a median of $107,656 a year, 37.1% above the national figure of $78,538 and 45% 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 12.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Olympia Fields village is valued at $289,900, 4.4% below the national figure and 62% above the $179,100 peer median, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 39% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 85.9% 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.

Olympia Fields village is the unusual combination of expensive to rent and cheap to buy: rent takes 39% of median income while homes cost only 2.7× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
