THE total number of Muslims in the world is 1.57 billion, nearly a quarter of the global total, according to a new survey of the world's Muslim population by the Pew Research Center. Almost two-thirds of Muslims live in Asia, with Indonesia providing the biggest contingent (203m), followed by Pakistan (174m) and India (160m).



One of the more surprising finds is that the European country with the highest Muslim population is not France or Germany, but Russia, where 16.5m adherents of Islam make up nearly 12% of the total national population. Compared with other studies, the report gives a lowish estimate for the number of Muslims in France (3.6m), as it does for the United States (2.5m); in both those countries, secular principles make it impossible to ask religious questions on a census.
