Young Americans becoming less religious

Historically, the percentage of Americans who said they had no religious affiliation... has been very small -- hovering between 5 percent and 10 percent. However, Putnam says the percentage of "nones" has now skyrocketed to between 30 percent and 40 percent among younger Americans…

While these young "nones" may not belong to a church, they are not necessarily atheists... "They have the same attitidues and values as people who are in church, but they grew up in a period in which being religious meant being politically conservative, especially on social issues."

Putnam says that in the past two decades, many young people began to view organized religion as a source of "intolerance and rigidity and doctrinaire political views," and therefore stopped going to church…

"That is the future of America," he says. "Their views and their habits religiously are going to persist and have a huge effect on the future."

This data is likely to reinvigorate an already heated debate about whether America is, or will continue to be, a "Christian nation."
