Countries with the largest Muslim populations

Key Takeaways

Indonesia has the largest Muslim population in any single country at 242 million—roughly 87% of its citizens.

South and Southeast Asia dominate the ranking, with Pakistan, India, and Bangladesh each home to more than 150 million Muslims.

This region is often overlooked for their Muslim populations as countries in the Middle East and North Africa tend to dominate conversations.

Islam is the world’s second-largest relgion and 1.8 billion Muslims are spread across every continent.

Indonesia (242 million), Pakistan (235 million), India (213 million), and Bangladesh (150 million) alone account for nearly 40% of the world’s Muslims.

Each of these densely populated nations has seen steady population growth over the past two decades, and fertility rates in Pakistan and Bangladesh remain above the global average.

Together, they underscore the demographic weight of South and Southeast Asia, regions sometimes overlooked when the focus is on the Middle East.
