Christians most populous of world's religions: report
Pew assembled data on the size and geographic distribution of 8 major religious groups, including non-believers.
It found that Christians make up about 32% of the world's population, followed by Muslims, the 2nd largest group, with 1.6 billion adherents.
Hindus were the 3rd largest group, numbering about one billion (15 percent), followed by Buddhists, at 500 million (7%) and Jews, who number 14 million (0.2%.)
The worldwide demographic study of more than 230 countries and territories found that more than 8 people in 10 -- about 5.8 billion people -- identify with a religious group.
More than 400 million people (6%) practice various folk traditions, including African traditional, aboriginal or folk religions, the global survey found.
The Pew Forum said that the study, in which religious affiliation was based on self-identification, did not attempt to measure the degree to which practitioners observe their faiths. - Rappler.com
