Islam by country

Adherents of Islam constitute the world's second largest and fastest growing major religious grouping, maintaining suggested 2017 projections in 2022.

[11][12][13][14][15][16][17] The diverse Asia-Pacific region contains the highest number of Muslims in the world, surpassing the combined Middle East and North Africa (short: Mena).

[18] Around 62% of the world's Muslims live in the Asia-Pacific region (from Turkey to Indonesia), with over one billion adherents.

[11] 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.

[31] Furthermore, there are concentrated Shi'a populations in Lebanon, Russia, China, Pakistan, Bangladesh and 10 sub-Saharan African countries.

[32] 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%[33] but less than 1%[34]).

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%[35] whose Taiyabi adherents reside in Sindh and Gujarat in South Asia.

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.

[317] 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.

In fact, Muslim population growth is expected to slow down in Asia (including the Middle East) and Africa, due to lower birth rates.
