Newly released census figures show Maine, Vermont and New Hampshire have the highest median ages in the country. Maine’s Office of Policy and Management says Census Bureau population estimates released Thursday show that Maine’s median age was 43.5 years last year, up from 43.2 years in 2011. That’s more than six years older than the U.S. median age of 37.4 years. Vermont had the second-highest median age, at 42.3 years. New Hampshire was third, with a median age of 42. Utah was the youngest state, with a median age of 29.9 years. Officials say among Maine counties, Lincoln is the oldest with a median age of 49.4 years. Androscoggin County was the youngest, at 40.5 years.
