eyeuse2badub. Although there is a reasonable amount of people getting baptised each year, the figure does not tell you how many witnesses have left, either faded or disfellowshipped etc. In other words they got 280,000 in through the front door but also a large number out the back door. JWfacts has some good graphs of this on his website.
Hopefully if it is published we will see how many publishers have left later this month .
