Rise in Religiously Unaffiliated Americans

One in five Americans doesn't have any religious affiliation. It's the fastest growing category of Americans, according to a new Pew survey. This group has jumped by a quarter in the last five years. That percentage is even higher when it comes to younger Americans. Some 35 million have no religious affiliation - with more than a third of that group labeling themselves atheist or agnostic. Still, more than two-thirds of the unaffiliated say they do believe in God and more than a third call themselves spiritual and a fifth say they pray each day. More than a third of younger millennials (18-22 year olds) have no ties to any religious group.
