David I agree with much of what you say. However we already know from independant sources that the JW religion is one of the most mobile in the world. It is reliabaly reported that two thirds of those brought up in the religion leave during their adulthood. So the facts already show that many leave.
I think the figures I stated are reasonable. The only thing I didn't include was the approx 1% who die each year. So if those figures are repeated year on year the only conclusion would be that they were indeed losing many. Suposing the baptisms were increasing at 10% per year and publishers increase was 2.5%. Surely that would mean that many were being lost.
I totally agree it does show a 2.5% increase, but it also shows that many are leaving. These figures are not a science they are purely approxamate.
For a more in depth picture of what we are speaking of, go to the jwfacts website where the figures are explained better than my effort.
