Which State Has the Highest Average Age?
According to the U.S. Census Bureau, Maine has consistently held the title for the oldest median age in the United States, with a median age of 44.8 as of the 2023 American Community Survey. This makes it the answer to the question, "What state has the highest average age?", based on the more accurate median age metric used by demographers. The state's aging population is influenced by both a higher share of older residents and the out-migration of younger people seeking opportunities elsewhere.
