As of last year, more than a third of Millennials were considered to be religious “nones” — the unaffiliated, agnostic or atheist population. In 2007, only a quarter of Millennials said they lived outside of a particular faith, according to a 2014 Pew Research Center study.
In the United States, the religiously unaffiliated make up the second-largest group after Christians. Seventy-two percent of the religiously unaffiliated are younger than 50.
Some worry that this trend will mean Millennials and their children won’t have the same values or beliefs in right and wrong as previous generations.
