Very interesting. I also liked the comment about the actual number of active churchgoers in the pews every Sunday.
I don't have the figures handy, but perhaps someone could compare when the largest year of growth for the JWs was and how it's doing now by comparison.
I remember doing this as I was leaving, and at that time it had hit a peak in around 1994, then began dropping off after that. Perhaps it's going back up again now, a decade later, but I don't think so.
Also, even back when I was an elder in the 70s to the early 90s, there were many, many congregations with considerably less than 100% meeting attendance. I was shocked at that, because my congregation always ran about 120% on Sundays. How that is figured is based on the total number of active publishers equals 100%.
Now, say the average attendance at Sunday meetings is 80% of publishers. According to this article, that means out of 6 million JWs worldwide, only 4.8 million would be "filling the pews" at any given meeting.
