The United States is aging, but New Jersey is aging faster than most of the country. According to the Brookings Institution, a national think-tank, the population of those under the age of 45 dropped 4 percent between 2000 and 2010, ranking New Jersey 37th among states with a young population. The average age of the country as a whole is 37.2, a marked difference from the 32.6 average age in 1990.
The Brookings analysis credited "aging in place" for much of the reason New Jersey and other older suburban areas are facing a maturing population. Many younger families are eschewing the Northeast suburbs and choosing to live in cities in the South and West.
