If you asked someone ten years ago which country has more Muslim residents, they’d answer "Indonesia" without blinking. It was the standard trivia fact. But things have changed lately. Populations aren't static, and the demographic race between Southeast Asia and South Asia has actually reached a massive turning point in 2026.
Honestly, the numbers are staggering. We aren't just talking about a few million people; we’re talking about the gravitational centers of a global faith. While many people still instinctively look toward the Middle East—places like Saudi Arabia or Egypt—when they think of Islam, the real "powerhouses" of the population have been in Asia for a long time.
The New King: Why Pakistan Is Now Number One
For decades, Indonesia held the title of the world’s most populous Muslim-majority nation. But as we move through 2026, Pakistan has officially overtaken Indonesia to claim the top spot.
How did this happen? It basically comes down to birth rates. Indonesia’s fertility rate has been cooling off for a while. Their government had some pretty successful family planning initiatives, and as the country became more middle-class and urbanized, families started getting smaller.
Pakistan, on the other hand, is still booming. According to data from the Pew Research Center and recent 2025-2026 census updates, Pakistan’s Muslim population has surged past 240 million. Indonesia is still right there, hovering around 236 to 238 million, but the trajectory is clear. Pakistan is growing faster.

Breaking Down the Top Five (2026 Estimates)
It’s not just a two-horse race. The global map of where Muslims actually live might surprise you, especially when you see how many live in countries where they aren't even the majority.
- Pakistan: ~242 Million. The new demographic leader.
- Indonesia: ~238 Million. The longtime champion, now a very close second.
- India: ~213 Million. This is the one that trips people up. Even though India is a Hindu-majority country, it houses one of the largest Muslim populations on the planet.
- Bangladesh: ~153 Million. A dense, South Asian hub that continues to grow steadily.
- Nigeria: ~120 Million. Africa’s biggest contributor to the list, where the population is split roughly down the middle between Christians and Muslims.
Why the "Arab World" Isn't the Biggest
There’s this common misconception that "Arab" and "Muslim" are interchangeable. It’s a total myth. Only about 15% to 20% of the world's Muslims are actually Arab.
Think about it this way: the combined Muslim populations of Saudi Arabia, the UAE, Qatar, Kuwait, and Jordan don't even come close to the population of a single province in Pakistan or a major island in Indonesia. The heart of the religion’s numbers is firmly in South and Southeast Asia.
Egypt is the largest Muslim country in the Arab world, with about 100 million people. That's a lot! But compared to Pakistan's 242 million? It's not even half.

The India Factor: What Most People Get Wrong
When discussing which country has more Muslim citizens, India is the "wildcard" that changes the whole conversation. Some demographers actually predict that by 2050, India could have more Muslims than any other country on Earth, even Pakistan.
Wait, how?
Basically, India's total population is so massive (over 1.4 billion) that even a "minority" percentage results in a number that eclipses entire nations. In India, Muslims make up about 14-15% of the population. That "small" slice equals more than 210 million people. You've got more Muslims living in India than in the entire Middle East combined.
The Role of Migration and the West
We also can't ignore what's happening in Europe and North America. While they don't affect the "top 10" list yet, the growth rates are notable. In countries like France and Germany, the Muslim population is around 6 million each. In the United States, it’s closer to 4 million but growing fast due to both immigration and higher-than-average birth rates.

What This Means for the Future
The "which country has more Muslim" question isn't just about bragging rights or trivia. It has real-world consequences for:
- Economic Markets: Halal tourism and Islamic finance are trillion-dollar industries. Companies are looking at Pakistan and Indonesia as the primary consumers of the future.
- Geopolitics: The political "center" of the Muslim world is slowly drifting away from the Gulf States and toward the "Big Three" in Asia (Pakistan, Indonesia, India).
- Cultural Influence: From Indonesian "Modest Fashion" to Pakistani cinema and Indian Sufi music, the cultural output of these regions is starting to dominate the global Islamic identity.
If you’re trying to keep track of these shifts, the most important thing to remember is that the "Global South" is where the action is. The population growth in Sub-Saharan Africa (specifically Nigeria and Ethiopia) is also something to watch. Nigeria is on track to become the third most populous country in the world by 2050, and its Muslim population will grow right along with it.
Actionable Takeaways for 2026
If you're a researcher, a business owner, or just a curious traveler, here is how you should view the landscape today:
- Focus on South Asia: If you want to reach the largest Muslim audience, Pakistan and India are the primary targets, not the Middle East.
- Watch the Demographic "Crossover": Pakistan is now the largest, but India is the one to watch for the 2030-2050 window.
- Recognize Diversity: A Muslim in Jakarta lives a very different life—culturally and linguistically—than a Muslim in Lahore or Cairo. Don't treat these populations as a monolith.
The numbers don't lie. The "center" of the Muslim world has moved east, and it's staying there.
