Footnotes:
India and Pakistan have Muslim populations of roughly similar size, and it is not entirely clear which is larger. The Pew Forum previously estimated that Pakistan had the world’s second-largest Muslim population and India had the third-largest; see the Pew Forum’s January 2011 report “The Future of the Global Muslim Population” and October 2009 report “Mapping the Global Muslim Population.” The difference between the rankings in this report and the previous reports is primarily due to a downward revision by the United Nations Population Division of its estimate of the size of Pakistan’s total population and an upward revision of the U.N. estimate of India’s total population.
