I noticed an interesting statistic that might surprise many. When people talk about Islam, they usually think of the Middle East, but the reality is quite different. It turns out that most of the largest Muslim countries are located in a completely different region — in South and Southeast Asia.

I looked at data from Pew Research Center for 2025, and the picture becomes quite clear. Indonesia simply dominates — there are 242 million Muslims living there, more than in any other country in the world. For comparison, that's almost the same as the entire population of the United States. Next is Pakistan with 235 million (96% of the population), India with 213 million, although that only accounts for 15% of its total residents.

The list then looks like this: Bangladesh 25M, Nigeria 1.4B, Egypt 104M, Iran 88M, Turkey 84M. If you look at Muslim countries with the highest proportion of believers, the top is quite different — Iran (99.8%), Yemen (99.1%), Somalia (99.8%), Afghanistan (99.7%). Almost 100% of the population.

What surprised me is the contrast between the number and the percentage. India ranks in the top 3 by absolute number of Muslims, but that's only 15% of its population. China is also on the list — 25 million Muslims, but that's only 1.4% of 1.4 billion residents.

Overall, when you look at this data, it becomes clear that understanding the global distribution of Islam requires a broader perspective. Muslim countries in Asia are not just religious centers; they are demographic giants with enormous influence on world politics and economics. It’s an interesting picture when you dig into the numbers.
