The Catholic share of the population in several Latin American countries has shrunk over the last 10 years, while a growing percentage of Latin American adults are religiously unaffiliated, describing themselves as atheist, agnostic or “nothing in particular.”
Catholicism still appears to be Latin America’s largest religion, according to Pew Research Center surveys in six of the region’s most populous countries: Argentina, Brazil, Chile, Colombia, Mexico and Peru.
Today, Catholics make up 46% to 67% of the adult population in each of these countries, while the share of adults who are religiously unaffiliated ranges from 12% to 33%.
