An international Pew Research Center's Forum on Religion & Public Life poll has found that Christianity remains the religion with the most adherents worldwide, while roughly one-third of people around the globe have no religious affiliation.
The comprehensive poll examined more than 230 countries worldwide, and asked respondents to identify which religion, if any, they belong to. The results determined that 32 percent of the world's population, 2.2 billion people, are Christians, 23 percent or 1.6 billion are Muslim, 15 percent or 1 billion are Hindu, and that 7 percent or 500 million are Buddhists. African, Asian, Native American and other folk religions are still practiced by 6 percent or 400 million people. Close to 1 percent belong to other established groups like the Baha'i faith, Jainism, Sikhism, Shintoism, Taoism, Tenrikyo, Wicca and Zoroastrianism, while Jewish people account for only 0.02 percent, or 14 million of the population.
The Pew poll found that almost half of the world's Christians are Catholic, while 37 percent identify as one of the Protestant traditions, which includes Anglicans. The Orthodox Communion numbers 12 percent, while minority denominations, sometimes referred to as "cults" like Mormons and Jehovah Witnesses only make up around 1 percent of the global Christian population.
