The Muslim population of the world is around one billion. 30% of Muslims live in the Indian subcontinent, 20% in Sub-Saharan Africa, 17% in Southeast Asia, 18% in the Arab World, 10% in the Soviet Union and China. Turkey, Iran and Afghanistan comprise 10% of the non-Arab Middle East.

There are 5 million Muslims in the United States.
O mankind! We created you from a single soul, male and female, and made you into nations and tribes, so that you may come to know one another. Truly, the most honored of you in God's sight is the greatest of you in piety. God is All-Knowing, All-Aware. (Quran, 49:13)
