In a major study, Barna surveyed teens ages 13-19, focusing on their religious identities and moral beliefs. As a generation born in a post-Christian culture, it may not be a surprise this demographic of youth is not strongly tied to a religion. "The percentage of Gen Z that identifies as atheist is double that of the U.S. adult population," Barna reports. The study shows teens, perhaps more than years before, have a "flexible sense of right and wrong." You can read more of the research here.
