Singapore tops the world as the most religiously diverse country, while the United States leads in that category among the ten most populous nations, according to a sweeping Pew Research Center analysis covering 201 countries and territories.
The report, “Religious Diversity Around the World,” measures how evenly each nation’s population is spread across seven groups: Christians, Muslims, Hindus, Buddhists, Jews, people of other religions, and those with no religious affiliation. Drawing on religious composition estimates from 2020—sourced from more than 2,700 censuses and surveys—researchers calculated a Religious Diversity Index (RDI) for every country in the study.
