Gilbert, AZ demographics: median age 36.1; 48.2% of adults 25+ hold a bachelor’s degree. Age, race, households, languages and education, ACS 2020–2024 with margins of error.

ACS 2020–2024 · Gilbert town, Arizona · Incorporated town · GEOID 0427400. The survey estimates a population of 280,262 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Gilbert is 36.1 years, with a 90% margin of error of 0.6 years. There are 96,363 households (±1,320). 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.

These are respondents’ residence patterns one year before their survey response, pooled across the five-year window. They are not a net migration count for 2025. A person can move to a different house within the same city or county; moves within the same county should not automatically be interpreted as new arrivals to the city.
