The Pew Research Center has released a report projecting a 35% increase in the world’s Muslim population over the next 20 years, “rising,” in the words of the Executive Summary, “from 1.6 billion in 2010 to 2.2 billion by 2030.” The Executive Summary also tells us:
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.
