Gen Z is not supposed to be the religious generation. Pollsters have spent two decades describing this cohort as the most secular in American history, the one that would finally break the chain of belief passed down from their grandparents.

New Harris Poll data suggests otherwise: 33% of Gen Z identifies as religious, compared with 18% of Boomers, 22% of Gen X and 19% of Millennials—making Gen Z the most religious-identifying generation in the survey. Their “neither religious nor spiritual” rate, 19%, is the lowest of any generation measured, lower than Boomers at 23%.
