I wonder what percentage from each group claims to have converted, as opposed to being raised in it?
Of course that doesn't count the "born agains" who grew up with it, didn't really take it seriously, then got zealous about it later in life.
Here's (one) link:

According to the site, the largest group is "Christian" which has 2 billion, the second being "Islam" which has 1.2 billion, and then "Hindu" and "Nonreligious (Atheist, Agnostic, Secular Humanist, None, etc)" being tied at about 900 million.
