Islam by country

World Muslim population by percentage (Pew Research Center, 2012)[1]

Adherents of Islam constitute the world's second largest and fastest growing major religious grouping, maintaining suggested 2017 projections in 2022.[2][3] As of 2020, Pew Research Centre (PEW) projections suggest there are a total of 1.9 billion adherents worldwide.[4][5] 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.[3][6]

Most Muslims fall under either of two main branches:

  • Sunni (87–90%, roughly 1.7 billion people)[7] or
  • Shia (10–13%, roughly 180–230 million people).[8]

In a 2010 publication, there were 50 Muslim-majority countries.[9][10] Islam is the majority religion in several subregions: Central Asia, Western Asia, North Africa, West Africa, the Sahel, and the Middle East.[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.[19] 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%.[11][20]

Africa has the 5th and 6th largest populations in Nigeria—5.3% and Egypt—4.9%.[11][20] 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.[21]

A common compromise figure ranks Sunnis at 90 percent and Shias at 10 percent.

  14. ^ Encyclopædia Britannica. Britannica Book of the Year 2003. Encyclopædia Britannica, (2003) ISBN 978-0-85229-956-2 p.306 According to the Encyclopædia Britannica, as of mid-2002, there were 376,453,000 Christians, 329,869,000 Muslims and 98,734,000 people who practiced traditional religions in Africa. Ian S. Markham, (A World Religions Reader. Cambridge, MA: Blackwell Publishers, 1996.) is cited by Morehouse University as giving the mid-1990s figure of 278,250,800 Muslims in Africa, but still as 40.8% of the total population. These numbers are estimates, and remain a matter of conjecture. See Amadu Jacky Kaba. The spread of Christianity and Islam in Africa: a survey and analysis of the numbers and percentages of Christians, Muslims and those who practice indigenous religions. The Western Journal of Black Studies, Vol 29, Number 2, June 2005. Discusses the estimations of various almanacs and encyclopedium, placing Britannica's estimate as the most agreed figure. Notes the figure presented at the World Christian Encyclopedia, summarized here, as being an outlier. On rates of growth, Islam and Pentecostal Christianity are highest, see: The List: The World's Fastest-Growing Religions Archived 11 July 2018 at the Wayback Machine, Foreign Policy, May 2007.
