This story is part of the New Boom series on millennials in America.

We've all heard that automated voice mail lady, telling us what to do after the beep. But fewer people than ever are leaving messages. And the millennials, they won't even listen to them — they'd much rather receive a text or Facebook message.

"I did have at one point in time like 103 unheard messages," says 31-year-old Antonia Kidd.

Barely half of millennials say they look to religion for guidance, but a higher percentage "talk to God," suggesting that the 18-to-34 demographic is more spiritual than sectarian, according to a new survey by the Integrated Innovation Institute at Carnegie Mellon University.

The survey of 2,000 U.S. men and women, ages 18-34, found that 62 percent said they talk to God, while 52 percent said they look to religion for guidance.
