WHO ARE THE MUSLIMS?
Over 1.2 billion people from a vast range of races, nationalities and cultures across the globe -- from the southern Philippines to Nigeria -- are united by their common Islamic faith. Only about 18% live in the Arab world; the world's largest Muslim community is in Indonesia; substantial parts of Asia and most of Africa are Muslim, while significant minorities are to be found in Russia, China, North and South America, and Europe.
