In 1910, the Azusa Street Revival led to an explosion of growth of the Pentecostal church around the United States, as members of the Silent Generation forever changed the religious landscape in America. In the 1970s, baby boomers had a similar experience as the Jesus Revolution swept across the country. Now, in 2025, Generation Z seems to be reversing the trend as many choose more traditional churches over contemporary ones.

The Catholic, Reformed, and Orthodox churches are some of the fastest-growing in the U.S. Membership in the Presbyterian Church of America between the ages of 18 and 29 has increased by 8.9% since 2018. The overall percentage of Gen Z Christians has increased from around 45% in 2023 to 51% in the current year. Catholic converts steadily climbed from around 50,000 in 2021 to 160,000 in 2025. Pew Research Center found that around 14% of all Catholics in the country are between the ages of 18 and 29. By contrast, a much smaller number of all Baptist or Pentecostal denomination members are within the same age range.
