According to a recent study (based on the 2010 world population of 6.9 billion) by The Pew Forum, there are:
2,173,180,000 Christians (31% of world population), of which 50% are Catholic, 37% Protestant, 12% Orthodox, and 1% other.
1,598,510,000 Muslims (23%), of which 87-90% are Sunnis, 10-13% Shia.
1,126,500,000 No Religion affiliation (16%): atheists, agnostics and people who do not identify with any particular religion. One-in-five people (20%) in the United States are religiously unaffiliated.
1,033,080,000 Hindus (15%), the overwhelming majority (94%) of which live in India.
487,540,000 Buddhists (7%), of which half live in China.
405,120,000 Folk Religionists (6%): faiths that are closely associated with a particular group of people, ethnicity or tribe.
58,110,000 Other Religions (1%): Baha’i faith, Taoism, Jainism, Shintoism, Sikhism, Tenrikyo, Wicca, Zoroastrianism and many others.
13,850,000 Jews (0.2%), four-fifths of which live in two countries: United States (41%) and Israel (41%).
So yeah
We Jews are 0.2% of the world population.
Muslims are about a quarter of the world population and rapidly increasing.
Christians are nearly a third.
But please by all means carry on trying to demonise and exterminate the tiny number of us that remain.
They're drawing Hitler moustaches on photos of kidnapped Jewish babies down the road from me.
But carry on
You're doing pretty well
