Indonesia's Muslim Population Below Pakistan's by 2030

The Pew Research Center on Religion & Public Life projects that the world's Muslim population is expected to increase by about 35 percent in the next 20 years, rising from 1.6 billion in 2010 to 2.2 billion in 2030. A notable development will occur in Pakistan, where the Muslim population is projected to surpass that of Indonesia. By 2030, the Muslim population in Pakistan is estimated to be 256.1 million, while Indonesia's Muslim population is projected to reach 238.8 million.

Muslim communities remain concentrated in the Asia-Pacific region. However, significant growth is expected in Sub-Saharan Africa over the next 20 years. Furthermore, while Muslims will remain a minority in Europe and America, their numbers are projected to increase as a percentage of the total population in these regions.
