Mexico
Catholic-majority (~78%) with rapidly growing evangelical and Pentecostal minorities (~11%) and a small but real "no religion" population (~10%), especially in the cities.
Localized version for English
Leaving the church in Mexico is not the same operation as leaving the church in the United States, even though both are Catholic exits in countries with strong Catholic histories. Mexican Catholicism is woven through almost everything: the Virgin of Guadalupe is a national symbol as much as a religious one, baptisms and quinceañeras and church weddings are family events that go beyond doctrine, and a grandmother’s rosary is a daily artifact in millions of households. You can stop believing entirely and still be expected to show up for those events for the rest of your life, and most of you do, because the alternative is hurting people you love over an interior position they cannot see.
There is also a major and growing Pentecostal and evangelical exit happening in Mexico, particularly in the north and in working-class urban areas. Many of these churches are imported American forms with intense expectations around tithing, pastor authority, and lifestyle compliance, and the deconstruction looks more like the ex-evangelical exit further north than like the cultural Catholic fade.
The Mexican family system absorbs a lot of unbelief without rupture as long as the leaver is willing to maintain the rituals. The ones that break families are usually the ones where someone publicly converts to a different faith — evangelical from Catholic, or atheist with a flag — in a way the family experiences as a rejection. Quiet drift is much easier to sustain than loud departure, and most people who leave well do so quietly.
