About this research<\/summary>\n

This report describes how the religious affiliation of people in six Latin American countries has changed over the past decade. It also examines their religious beliefs and practices. It focuses on several of the largest countries in the region: Brazil, Mexico, Colombia, Argentina and Peru are the five most populous<\/a> countries in Latin America and the Caribbean, while Chile has the region\u2019s seventh-largest population.<\/p>\n\n\n\n

Why did we do this? <\/strong><\/p>\n\n\n\n

Some of our recent reports on religion and spirituality around the world have focused on religious switching<\/a>, beliefs about life after death<\/a> and public opinion on Pope Francis<\/a>.<\/p>\n\n\n\n

How did we do this? <\/strong><\/p>\n\n\n\n

This report is based mainly on a Pew Research Center survey conducted in spring 2024 that included more than 6,200 Latin American adults (ages 18 and older).<\/p>\n\n\n\n

Here are the questions and responses used for this report<\/a>, along with the survey methodology<\/a>.<\/p>\n\n\n\n

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%.<\/p>\n\n\n\n

But the Catholic shares have dropped by 9 percentage points or more in all six countries over the past decade, while the percentages of adults who are unaffiliated have risen by 7 points or more. In several countries, unaffiliated adults \u2013 sometimes called religious \u201cnones\u201d \u2013 now outnumber Protestants.<\/p>\n\n\n\n
