…The world’s Muslim population is expected to increase by about 35% in the next 20 years, rising from 1.6 billion in 2010 to 2.2 billion by 2030, according to new population projections by the Pew Research Center’s Forum on Religion & Public Life.
Globally, the Muslim population is forecast to grow at about twice the rate of the non-Muslim population over the next two decades — an average annual growth rate of 1.5% for Muslims, compared with 0.7% for non-Muslims. If current trends continue, Muslims will make up 26.4% of the world’s total projected population of 8.3 billion in 2030, up from 23.4% of the estimated 2010 world population of 6.9 billion.
• The Muslim population in sub-Saharan Africa is projected to grow by nearly 60% in the next 20 years, from 242.5 million in 2010 to 385.9 million in 2030. Because the region’s non- Muslim population also is growing at a rapid pace, Muslims are expected to make up only a slightly larger share of the region’s population in 2030 (31.0%) than they do in 2010 (29.6%).
• Various surveys give differing figures for the size of religious groups in Nigeria, which appears to have roughly equal numbers of Muslims and Christians in 2010. By 2030, Nigeria is expected to have a slight Muslim majority (51.5%).
