How many people practice paganism?

At least of 400,000 in the USA.
In the world, only about three million people are Witches. It seems like a big number but it really isn't if you consider that the earth holds at least at least three billion people.

In America about 38 percent of people believe in paganism, more than believe in Christianity.

In Europe the Statistics are even higher, as almost half of all Europeans believe they are Witches.
