We're number one, we're number one! Maine tops the list of the oldest population in the United States. Maine's median age was 43.5 years last year, that is up from 43.2 years in 2011.
I think that most Mainers like the fact that the state isn't crowed and in the past year, the state didn't gain many more residents. The latest United States Census data shows, that Maine gained 648 new residents from July 2011 to July 2012, for a total of 1,329,192.
