or Shia (10-13%, roughly 180–230 million people).See * * * * Islam is the dominant religion in Central Asia, Indonesia, Middle East, North Africa, the Sahel and some other parts of Asia. The diverse Asia-Pacific region contains the highest number of Muslims in the world, easily surpassing the Middle East and North Africa. South Asia contains the largest population of Muslims in the world. One-third of Muslims are of South Asian origin. Islam is the dominant religion in the Maldives, Afghanistan, Pakistan, and Bangladesh. India is the country with the largest Muslim population outside Muslim-majority countries with about 200 million adherents. The various Hamito-Semitic, Arab, Berber, Turkic, and Iranic countries of the greater Middle East-North Africa (MENA) region, where Islam is the dominant religion in every country other than Israel, host 23% of the world's Muslims. The country with the single largest population of Muslims is Indonesia in Southeast Asia, which on its own hosts 13% of the world's Muslims. Together, the Muslims in the countries of Southeast Asia constitute the world's third-largest population of Muslims. In the countries of the Malay Archipelago, Muslims are majorities in each country other than the Philippines, Singapore, and East Timor. About 15% of Muslims reside in Sub-Saharan Africa, and sizeable Muslim communities are also found in the Americas, China, and Europe. Western Europe hosts many Muslim immigrant communities where Islam is the second-largest religion after Christianity, where it represents 6% of the total population or 24 million people.


Islam is divided into two major denominations, Sunni and Shi'a. Of the total Muslim population, 87–90% are Sunni and 10–13% are Shi'a. Most Shi'as (between 68% and 80%) live in mainly four countries: Iran, Azerbaijan, Bahrain, and Iraq. The major surviving Imamah-Muslim Sects are Usulism (with nearly more than 10%), Nizari Ismailism (with nearly more than 1%) and Alevism (with slightly more than 0.5% but less than 1%According to Krisztina Kehl-Bodrogi, ''Syncretistic Religious Communities in the Near East'' edited by her, B. Kellner-Heinkele, & A. Otter-Beaujean. Leiden: Brill, 1997.). The other existing groups include Zaydi Shi'a of Yemen whose population is nearly more than 0.5% of the world's Muslim population, Musta’li Ismaili (with nearly 0.1% whose Taiyabi adherents reside in Sindh and Gujarat in South Asia. There are also significant diaspora populations in Europe, North America, the Far East, and East Africa), and Ibadis from the Kharijites whose population has diminished to a level below 0.15%. (with nearly around 1%), non-denominational Muslims, Quranist Muslims and Wahhabis (with nearly around 1–2% of the world's total Muslim population) also exist. According to the Pew Research Center in 2010, there were 50 Muslim-majority countries. Around 62% of the world's Muslims live in the Asia-Pacific region (from Turkey to Indonesia), with over one billion adherents. The largest Muslim population in a country is in Indonesia, a country home to 12.7% of the world's Muslims, followed by Pakistan (11.0%), and India (10.9%). About 20% of Muslims live in the Arab world.See: * Esposito (2002b), p.21 * Esposito (2004), pp.2,43 In the Middle East, the non-Arab countries of Iran and Turkey are the largest Muslim-majority countries, while Egypt and Nigeria in Africa have the same status. The study found more Muslims in the United Kingdom than in Lebanon and more in China than in Syria. The Indian state of Uttar Pradesh has more Muslims than any other Muslim-majority countries except Indonesia, Pakistan, Bangladesh, Egypt, Iran and Turkey.


Most of the percentages of Muslim populations of each country, if not stated otherwise, were taken from the study by the Pew Research Center report of ''5 facts about the muslim population in Europe'', 2017.
