Arlington, TX demographics: median age 33.7; 32.6% of adults 25+ hold a bachelor’s degree. Age, race, households, languages and education, ACS 2020–2024 with margins of error.

ACS 2020–2024 · Arlington city, Texas · Incorporated city · GEOID 4804000. The survey estimates a population of 397,742 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Arlington is 33.7 years, with a 90% margin of error of 0.4 years. There are 142,455 households (±1,783). 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.
