Median Age by Zip Code (ZCTA5) — Arizona

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northeastern Arizona, encompassing the Navajo Nation and surrounding tribal lands, exhibits notably lower median ages in the low-to-mid 20s range, reflecting younger demographic profiles common in Indigenous communities, while retirement-heavy areas in the northwest near Lake Havasu and Bullhead City as well as scattered Sun City-area zip codes in the Phoenix metro skew sharply older with median ages exceeding 55. The central Phoenix metropolitan cluster displays considerable heterogeneity, with university-adjacent zip codes near Tempe appearing in darker teal tones alongside yellow-hued retirement communities just miles away. Southern Arizona shows a mix of moderate median ages in the Tucson metro area, with pockets of younger populations near the U.S.-Mexico border contrasting against older communities in Green Valley and the surrounding Santa Cruz Valley.
