One-fifth of Americans are religiously unaffiliated — higher than at any time in recent U.S. history — and those younger than 30 especially seem to be drifting from organized religion. A third of young Americans say they don't belong to any religion.

NPR's David Greene wanted to understand why, so he gathered a roundtable of young people at a synagogue in Washington, D.C. The 6th & I Historic Synagogue seemed like the right venue: It's both a holy and secular place that has everything from religious services to rock concerts. Greene speaks with six people — three young women and three young men — all struggling with the role of faith and religion in their lives.
