The Muslim World
In “the Muslim world,” this paper includes all the 57 members of the Organization of the Islamic Conference (OIC). The total population of these countries is 1.3 billion. This is about 21 percent of the world population of 6.2 billion. Since this figure of 1.3 billion also includes non-Muslims, the number of Muslims in these countries would be less than 1.3 billion. However, there are also Muslims in non-Muslim countries, especially in India and China where they live in large numbers. Moreover, the number of Muslims has been continually rising even in Europe, Canada, the United States and Africa. Therefore, if non-Muslims are excluded from the population of 1.3 billion in Muslim countries, and the number of Muslims in non- Muslim countries is then added, that constitutes the total Muslim population of the world. However, we do not have the precise figure for this total. There are a number of estimates ranging from 1.3 billion to 1.8 billion.
