Morocco* 31,993,000 ~99 ~2
* Data for Turkey and Morocco come primarily from general population surveys, which are less reliable than censuses or large-scale demographic and health surveys for estimating minority-majority ratios (see Methodology). As a result, the percentage of the population that is Muslim in these two countries is rounded to the nearest integer.

The bulk of the world's Muslim population - more than six-in-ten (62%) - is located in Asia, a region that, for the purposes of this report, includes not only East Asian countries such as China but also countries as far west as Turkey. (For a complete breakdown of countries by region, see World Muslim Population by Region and Country.)
