Yes, that’s correct. Some of the reduction in number of congregations is a reduction in foreign language congregations that were deemed not viable. Some of it was also a consolidation in KHs in response to the financial troubles Watchtower experienced around 2015.
All numbers are subject to redefinition over time. This is a feature of statistics in general not just Watchtower statistics. A publisher today isn’t the same as 20 years ago and the same goes for other measures. Even an attender at the memorial isn’t the same today because Zoom attenders are now counted.
Nevertheless it remains the case that JW numbers, taken as a whole, compare very favourably with most other churches in western countries. There are 9 million JWs today compared with 6 million 25 years ago. There are 240,000 members of the Church of Scotland compared with 600,000 25 years ago. Whatever way you look at it that indicates significant growth of JWs and significant decline of the Church of Scotland. In the west most churches are declining like the Church of Scotland and few match the growth of JWs.
Scenic View you ask what I think of the generation teaching? I think it’s nonsense, obviously. That doesn’t change the fact that JWs are still growing contrary to your comments. Just because you or I might wish JWs to decline doesn’t make it so. There’s no point pretending that JWs are “losing badly” when the facts are the opposite. What’s the point of denying reality? Or impugning the motives of others who don’t go along with denying reality?
