The Sunni Muslims are predominant - 87-90% - with predominantly Shi'a concentration - 68-80% - in Iran, Pakistan, India and Iraq.
More than 300 million Muslims, or one-fifth of the world's Muslim population, live in countries where Islam is not the majority religion. These minority Muslim populations are often quite large. India, for example, has the third-largest population of Muslims worldwide. China has more Muslims than Syria, while Russia is home to more Muslims than Jordan and Libya combined.
