Key Context & Facts

• Pew Research Center's Religious Diversity Index (RDI) measures how evenly a country's population is distributed among the world's major religions. A score of 10 would mean perfectly equal distribution.
• Religiously homogeneous countries (RDI below 2.0) include Vatican City (100% Catholic), Morocco (99%+ Muslim), and Cambodia (96%+ Buddhist).
• Religious diversity does not always lead to conflict. Singapore, Taiwan, and South Korea demonstrate that highly diverse religious landscapes can coexist peacefully with good governance and social norms.

Final Thoughts

Singapore's position atop the religious diversity rankings reflects its extraordinary multicultural composition and effective governance of interfaith relations. The most religiously diverse countries tend to be either Asian nations with syncretic traditions or West African countries with balanced Muslim, Christian, and indigenous populations. Religious diversity is a fascinating lens through which to understand a country's history, migration patterns, and cultural dynamics.
