Wow! We're third on the list. Amazing. We're almost as many as the Muslims. And a larger group than the Roman Catholics. I guess we're mainstream, then.
This statistic would support what I stated, thanks. However, my real point was really more focused on the term Christian and not specifically the emphasis on religion. For each "religion" there is a good deal of nominal (in name only) adherents. In many places people do not take any faith serious but someone builds a church or mosque and proclaims all the inhabitants as adherents to that group all of a sudden...but no real change has taken place in the person (in the case of Christianity) or awareness of their inclusion in that religion (in the case of other religions such as Islam).
