is confucianism one of the worlds' largest religions?

I wouldn't say that Confucianism is a religion.

According 2 statistics: Possibly !

Confucianism is a pure philosophy.
Confucianism is not a religion.
Much like Buddhism it is a process for stilling the mind so that one can elevate their thought process, and bring it once again into a state of balance.

No. Many would argue that it shouldn't even be counted as a religion, including many of the people who follow it. Adherents.com includes it in "Chinese traditional religion", which is puts at 394 million (but that is including many beliefs, not just Confucianism)

There are five major religions. In no particular order other than alphabetical, they are:
Buddhism
Christianity
Hinduism
Islam
Judaism
