Countries with the Largest Muslim Population 2026 — 2.06 Billion Muslims Worldwide

Muslim Population 2026 — 2.06 Billion Across 195+ Countries

Islam is the world's second-largest religion, with approximately 2.06 billion followers, commonly known as Muslims or adherents of Islam. They are collectively referred to as the Ummah (the global Muslim community) also known as Muslims or adherents of Islam — more than one in every four people on Earth. Muslims are present in virtually every country on the planet, from Indonesia (242.7 million) to Iceland (fewer than 15,000). What most people do not realise is that the geographic heart of the Islamic world is not the Middle East but South and Southeast Asia, which together are home to more than half of all Muslims globally.

Islam is also the world's fastest-growing major religion — expanding at approximately 1.84% per year, faster than any other faith including Christianity (1.38%).

The primary driver is demographic: Muslim-majority countries have higher fertility rates of 3.1 children per woman (vs. world average of 2.4), as tracked in our global population by gender data. They also have a significantly younger age structure, meaning more women of childbearing age. The Organisation of Islamic Cooperation (OIC), the world's largest intergovernmental body after the United Nations with 57 member states, reflects this geographic spread. At this rate, Islam's global total is projected to reach 2.8 billion by 2050, nearly matching Christianity for the first time in history. The global religious demographics connect to our broader global population analysis and world GDP data.

Top 10 Countries with the Largest Muslim Population 2026

The chart below shows the ten countries with the most Muslims in absolute numbers. The scale is striking: Indonesia alone has more Muslims than all Arab countries combined. Pakistan and India are virtually tied for second place in total numbers, though India's Muslim share of its total population (approximately 14%) is far smaller than Pakistan's (nearly 97%).

The chart below breaks down the world's 2.06 billion Muslims by geographic region. Asia-Pacific dominates with 61% — meaning more than 1 in 2 Muslims on Earth lives in South or Southeast Asia. The Middle East and North Africa, despite being the birthplace of Islam, account for only 20%. Hover each bar to see the total Muslim population for that region and its projected growth rate through 2050.

Sub-Saharan Africa deserves special attention: its Muslim population is growing at the fastest pace of any region.

Nigeria alone has nearly 100 million Muslims, and countries like Ethiopia, Tanzania, Mali, Niger, and Senegal each have tens of millions more. The continent's high birth rates and young populations mean Africa will be home to a significantly larger share of world Muslims by 2050.

Europe currently has approximately 25–26 million Muslims (about 5–6% of its population), concentrated in France, Germany, the UK (see our UK population analysis), and the Netherlands. This growth comes primarily from immigration and their descendants. The Muslim diaspora in Western countries, particularly in Europe, North America, and Australia — represents an additional 30–40 million Muslims outside their countries of heritage. The interconnection between Muslim population growth and global economic trends is visible in our global financial markets analysis.

Muslim-Majority Countries — Which Nations Are 90%+ Islamic?

There are approximately 50 Muslim-majority countries, also called Islamic countries or Muslim nations. These are nations where more than 50% of the population is Muslim. Within this group, a number of countries have populations that are 95% or more Muslim, effectively representing near-total Islamic societies. These include the Maldives, Mauritania, Afghanistan, Western Sahara (disputed), Somalia, Yemen, and several others where non-Muslim populations are extremely small minorities.

The chart below ranks the countries with the highest percentage of Muslim population — note how these differ completely from the countries with the largest absolute numbers. Small nations like the Maldives (almost 100% Muslim) or Mauritania (99.9%) rank above Indonesia and Pakistan on the percentage scale. These nations are culturally and legally organized around Islamic principles, with Islam often enshrined in their constitutions as the state religion.

An important distinction: Saudi Arabia, birthplace of Islam and home of Mecca and Medina, has a Muslim population of approximately 99% but only ranks 16th in total Muslim numbers (31.5 million). Similarly, Iran is 99% Muslim but ranks 8th by total numbers (82.5 million). Turkey, officially a secular state since Atatürk's reforms in the 1920s, nonetheless has approximately 99% of its population identifying as Muslim — though the government maintains strict separation of religion and state.

Muslim Population as a Share of Total — Sunni & Shia Countries 2026

Understanding which countries have the highest percentage of Muslim population versus which have the highest total Muslim population reveals two very different pictures of the Islamic world. Below are key facts for the most significant Muslim-population countries by both measures.

• Indonesia (87% Muslim, 242.7M): The world's largest Muslim-majority country by population. Islam arrived in Indonesia primarily through Arab traders in the 13th–14th centuries. Indonesian Islam is known for its moderate, syncretic character. Indonesia’s economic growth connects to our financial markets analysis — blending Islamic practice with local Hindu-Buddhist traditions in many regions. Despite being Muslim-majority, Indonesia is constitutionally a secular state based on Pancasila principles.
• Pakistan (96.5% Muslim, 240.8M): Created specifically as a homeland for South Asian Muslims at Partition in 1947. Pakistan is constitutionally an Islamic Republic. It will likely surpass Indonesia as the world's most populous Muslim country by 2030, given its higher fertility rate (approximately 3.3 children per woman vs. Indonesia's 2.3). Approximately 85–90% of Pakistani Muslims are Sunni; 10–15% are Shia.
• India (14% Muslim, 200M): India's Muslim community — descended from both indigenous converts and Muslim rulers — is the world's largest Muslim minority. Despite being only 14% of India's population, the sheer size of India's total population (1.44 billion) means even a minority becomes one of the world's largest Muslim communities. India's Muslim population is growing slightly faster than its Hindu population.
• Bangladesh (91% Muslim, 150.8M): One of the most densely populated Muslim-majority nations. Bangladesh separated from Pakistan in 1971. Its Muslim population is overwhelmingly Sunni. Bangladesh maintains a secular constitution despite its near-total Muslim majority.
• Nigeria (~49% Muslim, 97M): Africa's most populous country is roughly split between Muslims (predominantly in the north) and Christians (predominantly in the south). Nigeria's Muslim population is growing faster than its Christian population and may form a clear majority by 2060, according to Pew Research projections.
• Egypt (90%+, 90M): The most populous Arab country and the largest Muslim-majority nation in the Arab world. Islam is the state religion under Egypt's constitution. The vast majority are Sunni Muslim, with a Coptic Christian minority of approximately 10%.
• Turkey (99%, 84.4M): Officially secular since 1923, yet 99% Muslim. Turkey's unique position — bridging Europe and Asia, secular constitution with overwhelming Muslim population — makes it a distinctive case in the global Muslim demographic picture. Istanbul was once the seat of the Ottoman Caliphate.
• Iran (99%, 82.5M): The world's primary Shia Muslim nation and the center of Shia Islamic governance. Approximately 90–95% of Iranian Muslims are Shia — making Iran the most important country for the world's 240–340 million Shia Muslims. Iran has been an Islamic Republic since the 1979 revolution.

Fastest Growing Muslim Regions — Projected Growth 2010 to 2050

Sub-Saharan Africa will experience the most dramatic Muslim population growth of any region by 2050. The chart below shows projected % growth from 2010 to 2050 for each major region. While Asia-Pacific and the Middle East will grow significantly, Sub-Saharan Africa's +170% projected growth is unmatched — driven by the world's highest fertility rates in countries like Niger, Mali, and Nigeria.

Muslim Population 2026 — Key Statistics by Country & Region

Muslim Population Growth — From 200 Million in 1900 to 2.8 Billion by 2050

The growth of the global Muslim population over the past century is extraordinary. In 1900, there were approximately 200 million Muslims worldwide, about 12% of the global population at the time. Today, the figure stands at 2.06 billion: a tenfold increase in just 125 years. This growth has outpaced overall world population growth, meaning Muslims represent a steadily growing share of humanity.

The chart below tracks the Muslim population from 1900 to 2026 and projects forward to 2060. The acceleration visible from the 1970s onward reflects both the post-colonial population boom in Muslim-majority countries and the continued high fertility rates that distinguish Muslim demographics from other religious groups. Pakistan is projected to overtake Indonesia as the world’s most populous Muslim country by approximately 2030. Nigeria could have more Muslims than either country by 2060–2070, given its explosive demographic growth trajectory.

The chart below tracks the historical growth of the world's Muslim population from 1900 to present day, with projections to 2060. Notice the steep acceleration from the 1970s onward — this coincides with the post-independence population boom in Muslim-majority nations across Asia and Africa. The projection line (dashed) shows Islam on track to nearly match Christianity in total followers by 2050.

The donut chart shows how the world's 2.06 billion Muslims are distributed by region. The dominance of Asia-Pacific (61%) is striking — nearly two-thirds of all Muslims live in South and Southeast Asia, not the Middle East. Hover over each segment to see the exact population and the projected growth rate for each region through 2050.

The donut chart below visualises the same regional data in a different format, showing proportional shares at a glance. Asia-Pacific's golden segment (61%) dwarfs all others. The center displays the total world Muslim population. Sub-Saharan Africa's blue segment (15%) is today's smallest major region but will grow dramatically — its share is projected to increase significantly by 2050 as fertility rates in West and East Africa remain high.

Muslim population growth projections 2026–2060 (BusinessStats Research · Pew Research Center): 2026: 2.06 billion (25% of world) · 2030: ~2.2 billion · 2050: 2.8 billion (30% of world) · Islam growing at 1.84%/year — fastest major religion · Key driver: 3.1 children/woman average · Pakistan overtakes Indonesia by 2030 · Near parity with Christianity by 2050 · Islam projected to surpass Christianity 2060–2100.
