People with no religious affiliation make up the third-largest global group in a new study of the size of the world’s faiths, placing after Christians and Muslims and just before Hindus. You can read the details at Pew Research
The study, based on extensive data for the year 2010, also showed Islam and Hinduism are the faiths mostly likely to expand in the future while Jews have the weakest growth prospects.
It showed Christianity is the most evenly spread religion, present in all regions of the world, while Hinduism is the least global with 94 percent of its population in one country, India.
Overall, 84 percent of the world’s inhabitants, which it estimated at 6.9 billion, identify with a religion, according to the study entitled “The Global Religious Landscape” issued by the Pew Forum on Religion and Public Life on Tuesday.
The Roman Catholic Church makes up 50 percent of that total, with Protestants — including Anglicans and non-denominational churches — at 37 percent and Orthodox at 12 percent.
