Faith on the Move, a study by the Pew Research Center’s Forum on Religion & Public Life, published on 8 March 2012, focuses on the religious affiliation of international migrants, examining patterns of migration among seven major groups: Christians, Muslims, Hindus, Buddhists, Jews, adherents of other religions and the religiously unaffiliated.

About 3% of the world’s population has migrated across international borders. While that may seem like a small percentage, it represents a lot of people. If the world’s 214 million international migrants were counted as one nation, they would constitute the fifth most populous country on the globe, just behind Indonesia and ahead of Brazil.
