Rapid Growth of Religiously Unaffiliated
Overall, religiously unaffiliated people are more concentrated among young adults than other age groups – 35% of Millennials (those born 1981-1996) are “nones.” In addition, the unaffiliated as a whole are getting even younger. The median age of unaffiliated adults is now 36, down from 38 in 2007 and significantly younger than the overall median age of U.S. adults in 2014 (46).
