You are correct Scotoma. Of course it all depends on the 'slice' of the statistics that are examined - especially in terms of percentage of gain.
For example, when a small country is cited in the Yearbook with publishers increasing from 12 to 24 over the previous year...oh my! They've had an increase of 100%. That's not such a 'big deal' when it's realized the the country's population is ten million.
In 1980 there was just over 2 million active JW's. Twenty years later the numbers jumped to 6 million. In the eyes of all of us active during those years, 'we' had grown beyond our wildest imagination. During that time the money was filling the contribution boxes and the push to build additional branches came with it.
From a personal perspective, I can only remember back to the time when Jehovah's Witnesses had 1 million publishers.
