produce more children than those who have no religious affiliation, so the world is getting more religious, not less – although there are significant geographical variations.
According , Christians form the biggest religious group by some margin, with 2.3 billion adherents or 31.2% of the total world population of 7.3 billion. Next come Muslims (1.8 billion, or 24.1%), Hindus (1.1 billion, or 15.1%) and Buddhists (500 million, or 6.9%).
The next category is people who practise folk or traditional religions; there are 400m of them, or 6% of the global total. Adherents of lesser-practised religions, including about 0.2% of the global population, concentrated in the US and Israel.
