This isn’t about excluding minority faiths within these nations, but rather highlighting the prevalent religious identity.

Latin America consistently shows high percentages of Christians. brazil, for example, reports over 86% of its population identifying as Christian. Similar trends are observed in countries like Mexico (83%) and Peru (89%).

Jewish-Majority Nations

Israel is the only country with a Jewish majority, with approximately 74% of the population identifying as Jewish. This reflects Israel’s unique past and religious significance.

Other religious Majorities

While the above represent the largest religious demographics, several countries have significant majorities adhering to other faiths. For example, in Laos, over 64% of the population identifies with Theravada Buddhism. Smaller nations may exhibit unique religious profiles due to historical and cultural factors.

Data Considerations

It’s important to note that these figures represent self-identification and may not reflect the depth of religious practice. Furthermore, demographic shifts are ongoing, and these percentages are subject to change. The Pew Research Center’s ongoing research provides valuable insights into these evolving trends. This data offers a snapshot of religious affiliation as of early 2026.
