Numbers, Facts and Trends Shaping Your World

Religious composition of the world’s migrants, 1990-2020

This interactive table shows the estimated religious breakdown of immigrants to, and emigrants from, countries and regions of the world. Click the “Living in” button to see how many immigrants have moved into each country and remain there. Click the “Born in” button to see how many emigrants have moved away from each country and are living elsewhere.

You also can choose between counts and percentages (estimated number vs. % of all migrants). And you can toggle between decades to see how much change has occurred over time.

For an explanation of key findings and the methods we used to generate these estimates, read “The Religious Composition of the World’s Migrants.”

Pew Research Center also has estimated the religious composition of each country’s overall population.

Who are migrants?

The United Nations counts international migrants as people of any age who live outside their country (or in some cases, territory) of birth – regardless of their motives for migrating, their length of residence or their legal status.

In addition to naturalized citizens and permanent residents, the UN’s international migrant numbers include asylum-seekers and refugees, as well as people without official residence documents. The UN also includes some people who live in a country temporarily – like some students and guest workers – but it does not include short-term visitors like tourists, nor does it typically include military forces deployed abroad. 

For brevity, this report refers to international migrants simply as migrants. Occasionally, we use the term immigrants to differentiate migrants living in a destination country from emigrants who have left an origin country. Every person who is living outside of his or her country of birth is all three – a migrant, an immigrant and an emigrant.

The analysis in this report focuses on existing stocks of international migrants – all people who now live outside their birth country, no matter when they left. We do not estimate migration flows – how many people move across borders in any single year.
