Answer:
the Middle East-North Africa region has the highest concentration of Muslims of any region of the world: 93% of its approximately 341 million inhabitants are Muslim, compared with 30% in sub-Saharan Africa and 24% in the Asia-Pacific region.
Muslims make up a majority of the population in 49 countries around the world. The country with the largest number (about 209 million) is Indonesia, where 87.2% of the population identifies as Muslim. India has the world’s second-largest Muslim population in raw numbers (roughly 176 million), though Muslims make up just 14.4% of India’s total population.
