Northglenn, CO demographics: median age 34.8; 27.7% of adults 25+ hold a bachelor’s degree. Age, race, households, languages and education, ACS 2020–2024 with margins of error.

ACS 2020–2024 · Northglenn city, Colorado · Incorporated city · GEOID 0854330. The survey estimates a population of 38,014 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Northglenn is 34.8 years, with a 90% margin of error of 1.5 years. There are 14,570 households (±507). 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.
