OK I got my world population infor from here.

If the JWs have an average of 6.7 million publishers and there are 6.7 billion people in the world then simple math tells us the publisher to population ratio is 1:1000 . I will update this thread as I get information which I do not have in front of me at the moment because I am at work.
In 1980 the worlds population was 4.5 million and yet there were 2.5 million witnesses - so the JW: World population ratio was 1:1800
In 1990 the worlds population was 5.2 million
CURRENT 1:1000 - I am using average publishers not peak publishers.
So there is no question they are growing - just not nearly as fast as from about 1981 -1993 when the growth rate was tremendous
