Why do most people in Latin America practice Christianity?

Latin America is home to more than 425 million Catholics – nearly 40% of the world’s total Catholic population – and the Roman Catholic Church now has a Latin American pope for the first time in its history. Yet identification with Catholicism has declined throughout the region, according to a major new Pew Research Center survey that examines religious affiliations, beliefs and practices in 18 countries and one U.S. territory (Puerto Rico) across Latin America and the Caribbean.
