ACS 2020–2024 · Indianapolis city (balance), Indiana · Consolidated-government balance · GEOID 1836003. The survey estimates a population of 885,860 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Indianapolis city (balance) is 34.3 years, with a 90% margin of error of 0.2 years. There are 362,961 households (±1,958). 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.

Household estimates exclude people living in group quarters from the household universe.
