Many religions heavily concentrated in one or two countries (Pew Research, 27 August 2014)
Earlier this summer, on World Population Day, we explained that half of the world’s population lives in just six countries. In many cases, the world’s major religious groups are even more concentrated, with half or more of their followers living in one or a handful of countries. For several years, demographers at the Pew Research Center have been studying the demographic characteristics of eight groups: Buddhists, Christians, adherents of folk religions, Hindus, Jews, Muslims, the religiously unaffiliated and followers of other religions. While Christians and Muslims are more widely distributed around the world, the other groups have a majority of their populations in just one or two nations, according to 2010 estimates from our Global Religious Landscape report.
