World Muslim Population: Current Numbers and Growth Trends
Islam is the second-largest religion in the world, practiced by a global community that spans nearly every country and continent. But how many Muslims are there exactly, where do most of them live, and how is that number expected to change in the coming decades? This guide summarizes current, publicly available demographic estimates — noting clearly that population figures are estimates and projections, not precise counts.
How Many Muslims Are There Today?
According to research published by the Pew Research Center, one of the most widely cited sources for global religious demographics, the world's Muslim population is estimated to be approaching two billion people. This makes Islam the second-largest religion globally by number of adherents, following Christianity.
It is important to note that population figures of this kind are always estimates, based on census data, surveys and demographic modeling — actual figures can vary between different research organizations and change as new data becomes available.
Where Do Most Muslims Live?
Contrary to a common assumption, the majority of the world's Muslims do not live in the Middle East. The Asia-Pacific region, encompassing South and Southeast Asia, is home to the largest share of the global Muslim population.
| Country (illustrative) | General Population Context |
|---|---|
| Indonesia | Largest national Muslim population in the world |
| Pakistan | Among the largest national Muslim populations |
| India | Home to one of the largest Muslim minority populations globally |
| Bangladesh | Among the largest national Muslim populations |

Is the Global Muslim Population Growing?
Demographic researchers, including those at Pew Research Center, project continued growth in the global Muslim population over coming decades. This projected growth is generally attributed to factors such as relatively younger population age structures and higher fertility rates in many Muslim-majority countries compared to some other regions — though such projections are estimates, subject to change based on evolving social and economic conditions.
A Global, Diverse Community
What population statistics cannot fully capture is the extraordinary diversity within the global Muslim community — spanning hundreds of ethnicities, languages and cultural traditions, from West Africa to Southeast Asia, from Central Asia to Western Europe and the Americas. This diversity is, in many ways, one of Islam's most defining historical characteristics, a product of the many centuries of peaceful trade, migration and scholarship covered throughout this blog series.
