ACS 2020–2024 · Glendale Heights village, Illinois · Incorporated village · GEOID 1729730. The survey estimates a population of 32,808 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Glendale Heights is 36.1 years, with a 90% margin of error of 1.5 years. There are 11,196 households (±419). Age and household distributions show how these totals are composed; they do not establish which neighborhood suits a particular person.

Every count and share is an estimate. “±” is a 90% margin of error (MOE); pp means percentage points. Derived shares use the category count divided by the named universe. Aggregated category MOEs and percentage MOEs are approximate. A margin larger than half its estimate is flagged as low precision. Blank source uncertainty is shown as unavailable, never zero.

Foreign born means not a U.S. citizen at birth; it includes naturalized citizens. Language categories describe speech at home among people age five and older. A language other than English at home does not establish that someone cannot speak English. This city page uses the published C16001 summary categories because the more detailed B16001 table does not provide these city records in this release.
