Christianity is starting to make a comeback in the U.S. and other western countries, led by young people.Why it matters: A decades-long decline has stalled, shaping the future of Gen Z, the drivers of the religion revival.“We’ve seen the plateau of non-religion in America,” says Ryan Burge, a political scientist at Eastern Illinois University. “Gen Z is not that much less religious than their parents, and that’s a big deal.”By the numbers: Data from Pew shows that, for decades, each age group has been less Christian than the one before it.Americans born in the 1970s are 63% Christian. 1980s babies are 53% Christian, and 1990s babies are 46% Christian.But there was no decline from the 1990s to the 2000s. Americans born in the 2000s are also 46% Christian.Stunning stat: Gen Z-ers — especially Gen Z men — are actually more likely to attend weekly religious services than millennials and even some younger Gen X-ers, Burge’s analysis shows.Between the lines: Young men are leading American’s religion resurgence.
