Glen Ellyn, IL population, income and ZIP codes

Glen Ellyn village is a small city in Illinois, with 28,270 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #72 of 1,462 ranked by population — larger than 95% of them. The median age here is 41.3 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 Glen Ellyn village earn a median of $133,346 a year, 69.8% above the national figure of $78,538 and 80% 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 5.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Glen Ellyn village is valued at $522,600, 72.2% above the national figure and 192% above the $179,100 peer median, while median gross rent runs $1,326 a month, 5.7% below the national figure, or roughly $15,912 across a full year. A household on the local median income would put about 11.9% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.9% 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.
