Question

main religion in latin america

Answer 1

The main religion in Latin America is Christianity — overwhelmingly Roman Catholicism due to Spanish and Portuguese colonization. Over the last few decades there has been strong growth of Protestantism (especially Evangelical and Pentecostal churches), plus continued presence of indigenous and Afro‑Caribbean syncretic traditions (e.g., Andean, Candomblé, Santería). A smaller but growing share of people identify as religiously unaffiliated, and there are small Jewish, Muslim and Buddhist communities.

If you’d like, I can give current percentage estimates (overall and by country), or a brief history of how these religious patterns developed. Which would you prefer?
