Islam by country

Islam is the world's second largest religion after Christianity. According to a 2010 study and released January 2011,[1][2] Islam has 1.57 billion adherents, making up over 23% of the world population.[3][4]

Islam is the predominant religion in the Middle East, the Sahel, the Horn of Africa, North Africa,[1][5][6][7] and some parts of Asia.[8] Large communities of Muslims are also found in China, the Balkans, India and Russia.[1][9] Other parts of the world host large Muslim immigrant communities; in Western Europe, for instance, Islam is the second largest religion after Christianity, where it represents 6% of the total population.[10]

According to the Pew Research Center in 2010 there were 49 Muslim-majority countries.[11] Around 62% of the world's Muslims live in South and Southeast Asia, with over 1 billion adherents.[12] The largest Muslim population in a country is in Indonesia, a secular nation home to 12.7% of the world's Muslims, followed by Pakistan (11.0%), India (10.9%), and Bangladesh (9.2%).[1][13] About 20% of Muslims live in Arab countries.[14] In the Middle East, the non-Arab countries of Turkey and Iran are the largest Muslim-majority countries; in Africa, Egypt and Nigeria have the most populous Muslim communities.[1][13] The study found more Muslims in the United Kingdom than in Lebanon and more in China than in Syria.

Muslim world

The term Muslim world (also known as the Ummah[2] or Islamosphere[3][4]) has several meanings. In a religious sense, the Islamic Ummah refers to those who adhere to the teachings of Islam, referred to as Muslims. In a cultural sense, the Muslim Ummah refers to Islamic civilization, exclusive of non-Muslims living in that civilization. In a modern geopolitical sense, the term Islamic Nation usually refers collectively to Muslim-majority countries, states, districts, or towns. Although Islamic lifestyles emphasise unity and defence of fellow Muslims, schools and branches (see Shi'a–Sunni relations, for example) exist. In the past both Pan-Islamism and nationalist currents have influenced the status of the Muslim world.
