JWs Ranked by Babylon the Great
Amazing, you said they are growing at 2-3%. I think they are down to 1.7% as I recall from stats at FreeMinds. There is no growth at all in 24 large countries. All the growth comes from the underdeveloped countries.

If they did, those underdeveloped countries would be as dry as the dust bowl.
And Islam is growing faster than all of them.
the islam ist the fastest in increasing - but the jws are the fastes in disfellowshipping
