Americans who don't identify with any religion are now 15% of the USA, but trends in a new study shows they could one day surpass the nation's largest denominations — including Catholics, now 24% of the nation.
"Will a day come when the Nones are on top? We can't predict for sure," says lead researcher Barry Kosmin.
But if Nones, now 22% of all adults ages 18 to 29, continue to gain among young adults, to draw more people "switching out" from denominations and to replace more religious older people, researchers forecast one in five Americans will be Nones in 20 years.
"There are so many misconceptions about who the Nones are. They're not New Age searchers or spiritual or even hardened atheists," says Kosmin. "They're a stew of agnostics, deists and rationalists."
