Glendale Heights, IL population, income and ZIP codes

Glendale Heights village is a small city in Illinois, with 32,864 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #56 of 1,462 ranked by population — larger than 96% of them. The median age here is 35.5 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 Glendale Heights village earn a median of $82,232 a year, 4.7% above the national figure of $78,538 and 11% 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Glendale Heights village is valued at $249,000, 17.9% below the national figure and 39% above the $179,100 peer median, while median gross rent runs $1,562 a month, 11.1% above the national figure, or roughly $18,744 across a full year. A household on the local median income would put about 22.8% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 64.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
