The municipal city limits span 1,961.1 sq mi (5,079.2 km 2), encompassing the urban core, a joint military base, several outlying communities, and almost all of Chugach State Park.

The Anchorage metropolitan area, which includes Anchorage and the neighboring Matanuska-Susitna Borough, had a population of 398,328 in 2020, accounting for more than half the state's population.
