Two regions,parts of South and Southeast Asia together with a belt across North and sub-Saharan Africa,hold the bulk of the world’s Muslim population, often surprising learners who first encounter Islam through Middle Eastern headlines. Indonesia tops the global ranking with more than 230 million Muslims, putting Southeast Asia ahead of every Arab-majority state. Pakistan, India, and Bangladesh each clear 100 million, and the global Muslim population now sits near 1.9 billion, roughly a quarter of humanity.
This guide ranks the ten countries with the most Muslims, explains why Asia,not the Arab world,leads global Muslim demographics, and flags the large Muslim populations hiding inside non-Muslim-majority nations like India and China.
Indonesia Holds the World’s Largest Muslim Population
A chain of more than 17,000 islands stretching from Sumatra to Papua is home to more Muslims than any single country on the planet. Indonesia reports roughly 230 million Muslim residents, a figure that puts its national Muslim population ahead of the entire population of Russia. About 87% of Indonesian citizens identify as Muslim, making the country the most populous Muslim-majority nation on Earth and a clear answer to the question of which country has the most Muslims.
The size of Indonesia’s Muslim community surprises most people outside Asia, and the reason sits in centuries of Indian Ocean commerce. Muslim traders reached the archipelago by the 13th century, and the religion spread through port cities, merchant networks, and royal courts rather than through conquest. Today Java alone holds more Muslims than Egypt, Saudi Arabia, and Syria combined.
Trade Routes Built Indonesia’s Muslim Majority
Spice routes linking Gujarat, Hadramaut, and the Malay world carried Sufi teachers, scholars, and merchants into Indonesian harbors. Walisongo, the nine saints credited with Islamizing Java, used trade guilds and mosque schools to convert coastal populations between the 15th and 16th centuries. The interior highlands held onto older Hindu and animist traditions far longer, which is why pockets of non-Muslim identity persist in Bali, Flores, and parts of Sumatra today.
Why Indonesia Outranks the Arab World
Saudi Arabia, the custodian of Mecca and Medina, hosts only about 32 million people, roughly an eighth of Indonesia’s Muslim count. Egypt carries close to 90 million Muslims and ranks sixth globally. The gap between Indonesia and the Middle East reflects birth rates, not religious devotion: Indonesia’s total fertility rate held above replacement longer than most Arab states, and its young median age keeps the population curve climbing.
The Top 10 Countries With the Most Muslims, Ranked
Four Asian nations dominate the top of any ranking of Muslim populations by total count, and three African countries round out the leaders. The table below pairs each country’s absolute Muslim population with the national percentage, because that second number is what flips India’s position, Egypt’s place, and the rest of the field when you switch metrics.
| Rank | Country | Muslim Population | Share of Citizens |
|---|---|---|---|
| 1 | Indonesia | ~230 million | ~87% |
| 2 | Pakistan | ~220 million | ~96% |
| 3 | India | ~200 million | ~14% |
| 4 | Bangladesh | ~150 million | ~91% |
| 5 | Nigeria | ~110 million | ~50% |
| 6 | Egypt | ~90 million | ~90% |
| 7 | Ethiopia | ~40 million | ~34% |
| 8 | Iran | ~85 million | ~99% |
| 9 | Turkey | ~80 million | ~95% |
| 10 | Algeria | ~40 million | ~99% |
The Total-vs-Percentage Flip
India holds the third-largest Muslim community on Earth, yet Muslims make up only about 14% of its 1.4 billion citizens. Ranked by share instead of total, India drops out of the top 10 entirely and Ethiopia falls below half its current position. Egypt, Iran, and Algeria keep their spots under both metrics because their populations are nearly uniform in religious affiliation.
What Changes If You Rank by Percentage Alone
Switch the lens to share of citizens and the top of the list becomes a parade of small, deeply Muslim states. The Maldives, Mauritania, Somalia, and Djibouti each report Muslim populations above 95% of the national total, but none breaks 20 million in absolute terms. That contrast is exactly why anyone tracking global Muslim demographics needs both numbers side by side.
Why Asia, Not the Middle East, Dominates Global Muslim Demographics
Walk into any mosque in Kuala Lumpur, Dhaka, or Karachi and you’ll find yourself inside a community larger than the entire Muslim population of the Arabian Peninsula combined. More than 60% of the world’s Muslims live in the Asia-Pacific region, a share that overturns the assumption that Islam’s center of gravity sits in the Arab world. South and Southeast Asia hold roughly 1 billion Muslims, while the Middle East-North Africa region carries around 600 million despite a higher concentration rate.
The Middle East-North Africa region is roughly 93% Muslim, giving it the highest concentration by percentage even though its total population is smaller than Asia’s. Africa and Asia together host more than 85% of the world’s Muslims, leaving the Americas, Europe, and Oceania to share what’s left.
Africa’s Quiet Rise Into the Top Five
Nigeria already ranks fifth globally by total Muslim population, and projections from Pew Research suggest it could climb into the top three before 2050. Sub-Saharan Africa shows the fastest proportional growth in Muslim demographics worldwide, driven by higher birth rates and a younger median age than any other region. Egypt, Ethiopia, and the Sahel states from Mali to Niger contribute the bulk of that African total.
Europe, the Americas, and the Muslim Diaspora
Europe hosts roughly 25 to 30 million Muslims, with France, Germany, and the United Kingdom carrying the largest communities. The US Muslim population sits near 4 million, accounting for about 1% of the national total. These diaspora populations matter for understanding labor migration patterns, religious freedom debates, and the cultural reach of Muslim communities well beyond the 57 member states of the Organisation of Islamic Cooperation.
Countries With Large Muslim Minorities Often Overlooked
China’s Muslim population is estimated at 20 to 25 million, mostly Uyghur and Hui, yet the country never appears on Muslim-majority lists. Russia carries 15 to 20 million Muslims across the North Caucasus, the Volga region, and Tatarstan. Ethiopia, already listed above for its 40 million Muslims, qualifies as a Muslim-minority nation because Muslims make up only a third of its citizens. India rounds out the overlooked group with more Muslims than Egypt and Iran combined.
Counting only Muslim-majority countries misses the majority of South Asian Muslims, all of China’s Muslims, and most of Russia’s. These minority populations shape diaspora networks, labor migration routes, and geopolitical debates that rarely show up in standard country rankings.
India as the Outsized Minority Case
India’s 200 million Muslims form the world’s third-largest Muslim population, larger than every country in the Middle East except Egypt and Saudi Arabia. The community spans Sunni, Shia, Bohra, and Ahmadiyya branches, and its size shapes regional politics in Kerala, West Bengal, and Uttar Pradesh. Treating India as a Hindu-majority country with a footnote on Muslims misses how its internal diversity compares to whole Muslim-majority states.
Why Minority Populations Get Skipped
Most lists of Muslim countries pull from the 57 OIC members, which excludes China, India, and most non-OIC states. Census practices also differ: India counts religion explicitly, China restricts the question, and Russia stopped including religion in its national census after 1937. The result is a knowledge gap that flattens the demographic reality of roughly 300 million Muslims living as minorities.
How Sunni and Shia Majorities Reshape the Country Rankings
About 85% of the world’s Muslims are Sunni, leaving Shia Islam as the second-largest branch with most followers concentrated in Iran, Iraq, Azerbaijan, and Bahrain. Iran alone accounts for nearly 40% of the global Shia population, and Iraq adds another 25 to 30 million. The sectarian split changes how analysts interpret demographics, foreign policy alliances, and even how census data is collected and reported.
Understanding this split helps you avoid treating the Muslim world as a single bloc when comparing national populations. Sectarian composition influences everything from embassy staffing to seminary funding, and it shows up clearly in the religious freedom records maintained by the US State Department and Pew Research.
Where Sunnis Dominate the Top 10
Indonesia, Pakistan, Bangladesh, Nigeria, Egypt, Turkey, and Algeria are all Sunni-majority, and that holds true for most of the top 10 by total population. Sunni Islam in these countries usually follows either the Hanafi school, dominant across South Asia and Turkey, or the Shafi’i school, dominant in Indonesia and parts of Egypt. The Maliki school prevails across North and West Africa.
Where Shia Majorities Reshape the Picture
Iran, Iraq, Azerbaijan, and Bahrain carry Shia majorities that change how their demographics get reported in regional comparisons. Iran is the only top-10 country where Shia Islam is the state religion, and its roughly 85 million Muslims are overwhelmingly Twelver Shia. Iraq sits below the top 10 in absolute Muslim count but its 30 to 35 million Shia Muslims give it outsized influence over regional scholarship and pilgrimage networks.
Projected Growth and What the Numbers Will Look Like by 2050
Pew Research projects the global Muslim population will approach 3 billion by 2050, driven by higher birth rates and a younger median age in Muslim-majority nations. The total adds roughly 1 billion Muslims over a 30-year window, faster than any other major religion. By 2050, Muslims could make up close to 30% of the global population, up from about 25% today.
Treat the current rankings as a snapshot. Indonesia and Pakistan will keep their top spots in absolute totals, while countries with higher fertility rates will rise in rank as demographics shift.
Sub-Saharan Africa Will Climb Fastest
Nigeria, Niger, Mali, and the Democratic Republic of the Congo show the steepest growth curves in any Pew projection. Nigeria alone could add 100 million Muslims by 2050, pushing it past Indonesia and Pakistan into a top-three position by mid-century. Ethiopia and Tanzania round out the African countries expected to gain the most Muslim residents per decade.
What Stays Stable Through 2050
The Middle East-North Africa region is already 93% Muslim, leaving little room for proportional growth even as total population climbs. Iran’s share of the global Muslim total will likely shrink slightly as African and South Asian populations expand faster. Europe’s Muslim population could double from roughly 25 million to 50 million, driven mostly by immigration and higher birth rates among Muslim-minority communities.
Bottom Line
Asia holds the largest Muslim community in the world, Indonesia leads the global ranking by a wide margin, and the answer to which country has the most Muslims depends on whether you measure by total count or share of citizens. Pakistan, India, and Bangladesh together carry more Muslims than the entire Middle East, and African nations like Nigeria and Egypt add another 200 million on top of that. Get comfortable with both metrics, and the global picture becomes clear: Islam is a South and Southeast Asian religion in scale, an Arab religion in origin, and an African religion in its fastest growth.
FAQ
Which country has the highest Muslim population in the world?
Indonesia holds the highest Muslim population in the world, with roughly 230 million Muslims, or about 87% of its national population. It ranks first ahead of Pakistan and India regardless of whether you measure by total count or by share of citizens, though Pakistan narrows the gap when percentage is considered.
What are the top 10 countries with the most Muslims?
Indonesia leads the list with roughly 230 million Muslims, followed by Pakistan, India, Bangladesh, Nigeria, Egypt, Iran, Turkey, Algeria, and Ethiopia, according to Pew Research and recent census data. The exact order shifts when you rank by percentage, since India and Ethiopia drop out and small states like the Maldives climb in.
Is Islam the fastest-growing religion?
Pew Research projects the global Muslim population will approach three billion by 2050, making Islam the fastest-growing major religion worldwide. The growth comes from higher birth rates and a younger median age in Muslim-majority countries, especially across Sub-Saharan Africa and South Asia.
How many Muslims live in Europe?
Europe hosts roughly 25 to 30 million Muslims, with France, Germany, and the United Kingdom carrying the largest national communities. The total is projected to reach 50 million or more by 2050, driven by immigration and higher birth rates among Muslim-minority populations.
Which countries have Islam as the official state religion?
Roughly two dozen nations,Saudi Arabia, Iran, Pakistan, and Egypt among them, alongside most members of the Organisation of Islamic Cooperation,have formally enshrined Islam as their state religion. Indonesia and Turkey are notable exceptions within the top 10, since both keep Islam as the majority faith without naming it an official state religion in their constitutions.
What percentage of the world is Muslim?
Muslims make up roughly 25% of the world’s population, with estimates near 1.9 billion as of the latest Pew Research figures. That share is projected to approach 30% by 2050, making Islam the second-largest religion globally after Christianity.
