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.

In 2009, when the Great Recession took hold of the United States, Americans reversed a long-running trend in polling: For the first time since Gallup first asked the question in the 1980s, more Americans said they favored economic growth over protecting the environment.
