The most believed religions in the world are Christian (which includes Protestant, Catholic, Anglican, Jehovah Witnesses, etc.) It has a following of approximately 2.3 billion followers. I think it is the most poplar because it is a hope that there is life after death and that once we die that is it. It has a lot of good things which it talks about.

The next major religion with approximately 1.5 billion people is Islam, which includes Shiite, Sunni, etc. It is the more popular in the eastern countries than in the west but many immigrants are now coming to America, Canada etc. So it is starting to become more and more popular there too.

There are also the people that have no religious views like Atheist, secular, agnostic etc.. Most of them just think that there is nothing after you die and that that is it. They also are very skeptical to believe anything they have not seen.

The fifth largest of all the religions is Chinese traditional religion which includes Confucianism. As the name obviously states it is primarily found in China. It has a following of almost 400 millions people. China has a very large amount of people so it makes sense that it would have a large religion following.
