A Report on the Size and Distribution of the World's Muslim Population
Map: Distribution of Muslim Population by Country and Territory
Only countries with more than 1 million Muslims are shown
Roll over a country bubble to see its estimated 2009 Muslim population, the percentage of its population that is Muslim and the percentage of the world Muslim population it represents.
* Indicates the use of a source with a small enough sample size to make these estimates somewhat less reliable. Due to this greater margin of error, percentages are rounded to the nearest integer rather than to the first decimal place and are therefore more approximate (~). The only exception to this rule is the display of Turkey's percentage of world population as 4.7% rather than ~ 5%.
"--" indicates that the number of Muslims is too small to be reliably estimated.
