Catholic-to-Protestant switching trend

Pew’s 2024 cross‑national surveys (24 countries plus the U.S. Religious Landscape Study) show that adults raised Catholic are switching out at higher rates than they switch in across many countries, while Protestantism registers net gains in several places. The pattern is based on comparing childhood religion to current affiliation, capturing moves to other Christian denominations and to unaffiliated identities. — Religious switching at scale reshapes electoral coalitions, civic institutions, and cultural authority where Catholic institutions have historically been dominant.
