# Islam by country

Adherents of Islam constitute the world's second largest and fastest growing major religious grouping, maintaining suggested 2017 projections in 2022. As of 2020, Pew Research Centre (PEW) projections suggest there are a total of 1.9 billion adherents worldwide. Further studies indicate the worldwide spread and percentage growth of Islam, may be attributed to high birth rates followed by a trend of worldwide adoption and conversion to Islam.
Most Muslims fall under either of two main branches:
* Sunni (87–90%, roughly 1.7 billion people)
* Shia (10–13%, roughly 180–230 million people).
In a 2010 publication, there were 50 Muslim-majority countries. Islam is the majority religion in several subregions: Central Asia, Western Asia, North Africa, West Africa, the Sahel, and the Middle East.
The diverse Asia-Pacific region contains the highest number of Muslims in the world, surpassing the combined Middle East and North Africa $_{(short:Mena)}$. Around 62% of the world's Muslims live in the Asia-Pacific region (from Turkey to Indonesia), with over one billion adherents. Asia hosts the world's top 4 largest domestic populations, starting with Indonesia at 12.7% of the world, followed by Pakistan—11.1%, then India—10.9%, and Bangladesh—9.2%.
Africa has the 5th and 6th largest populations in Nigeria—5.3% and Egypt—4.9%. The Middle East hosts 7th and 8th with both Iran and Turkey holding an estimated 4.6%. Only about 20% of Muslims live in the Arab world.

## Regional comparisons

South Asia has the largest population of Muslims in the world, with about one-third of all Muslims being from South Asia. 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 more than 200 million adherents.
The Middle East-North Africa (MENA) region hosts 23% of the world's Muslims, and Islam is the dominant religion in every country in the region other than Israel. and Cyprus
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 in the majority in Brunei, Indonesia, and Malaysia.
About 15% of Muslims reside in Sub-Saharan Africa, and sizeable Muslim communities are also found in the Americas, Russia, 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.

## Denominations

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. Furthermore, there are concentrated Shi'a populations in Lebanon, Russia, China, Pakistan, Bangladesh and 10 sub-Saharan African countries. The major surviving Imamah-Muslim Sects are Usulism (with around 8.5% of the total Muslim population), Nizari Ismailism (with around 1%) and Alevism (with slightly more than 0.5% but less than 1%). The other existing groups include Zaydi Shi'a of Yemen whose population is around 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 around 1%), non-denominational Muslims, Quranist Muslims and Wahhabis (with around 1–2% of the world's total Muslim population) also exist.
A study from the Pew Research Center in 2012 found that many Muslims (one out of five in 22 Muslim majority countries) identify as non-denominational or "Just a Muslim". This non-denominational affiliation is most common in Southern and Eastern Europe as well as Central Asia, with minority populations in Southeast Asia and sub-Saharan Africa. The study found that a median percentage of 74% of Muslims in Kazakhstan, 65% in Albania, 64% in Kyrgyzstan, 56% in Indonesia, 55% in Mali, and 40% in Cameroon identify this way. However, it is much less common in parts of Africa, the Middle East, and South Asia.

## Projected demographic changes

The Pew Research Center, has established a continued trend since its 2017 report into 2022. Islam continues to close the gap between itself and Christianity, while constituting the world's second largest religious group it also continues to be the fastest-growing major religious grouping.
A Pew Research Study in 2015 found that the Muslim population was expected to grow twice as fast (70%) as the world population by 2060 (1.8 billion in 2015 to 3 billion by 2060). This expected growth is much larger than any other religious group. Muslims are likely to constitute roughly 26.3% of the world's total population by 2030. This expected growth is attributed to Muslim families generally having more children as well as the fact that the Muslim population has the youngest median age of any religion. Furthermore, increased healthcare conditions in Muslim majority countries are currently increasing life expectancy and decreasing child mortality, which, if trends continue this way, will also contribute to the growth of the Muslim population more than any other religious group. These trends are not for every region, however. In fact, Muslim population growth is expected to slow down in Asia (including the Middle East) and Africa, due to lower birth rates.
The largest Muslim population growths are expected to be in the Middle East and Africa. Furthermore, Pakistan is projected to be the country with the largest Muslim population by 2030. Muslims are expected to grow to 8% (52.8 million) of the total population of Europe, and this growth is expected to be the largest in the western European countries. Russia will have the largest total population of Muslims in Europe, however. Most of these changes are expected to come from immigration.
In the Americas, Canada’s Muslim population is expected to increase to 6.6% and United States' to 2% by 2030. These increases, much like Europe, are expected to be driven mainly by immigration.
