That would be an estimation of the total number of people who identify as being Muslim, but many people who identify as being Muslim would also identify as being Christian, Buddhist, Hindu or some other religion.  Even for people who do identify as Muslim, how seriously they take the religion varies a lot between individuals and between places.  The accurate rank of Islam in a “rank of the world’s largest religion” is difficult to establish.

There isn’t a good answer for the ranking of Islam in the United States either, since the faith is so multifaceted, and how people practice the faith varies so much.  Overall, the U.S. census says that 1.3% of the US population identifies as Muslim.
