A study released by the Pew Forum last week demonstrates that the future of the religious world is rapidly and dramatically changing. Differences in fertility rates and the high incidence of conversion make Islam the world’s fastest-growing religion. And, if current rates continue, by 2070 Islam could be the world’s largest.
Between now and 2050 the number of Muslims is projected to rise to 2.8 billion, a 35 percent increase. While India will continue to be predominantly Hindu, it will also be home to the world’s largest Muslim population. And, by 2050, Muslims are slated to make up 10 percent of Europe’s population and be the largest non-Christian religion in the U.S….
Changes are coming, though, for Christianity. The trend of southward expansion will continue. By 2050, 4 out of every 10 Christians will live in sub-Saharan Africa. Christianity will grow, but not in wealthier countries. In the U.S., the Christian majority will slip from roughly three-quarters of the population to a still-healthy two-thirds.
