Yes and as Cofty said, closing congregations is the one to watch. And I think we'll see a ton of that in the next few years, as a result of dwindling numbers and aging congregations, lack of elders, and financial troubles. It's already started. Correct me if I'm wrong, but didn't the number of congregations actually decline in the United States last year, and in Germany? For the first time ever?
On top of that, census results from Australia and Canada show declining numbers of people identifying as JWs.
On top of that there has been a drive to baptise JW children younger. Yet even despite that push the baptism figures continue to fall.
Plus many countries that could be relied upon for growth in years past are no longer driving JW increases. Countries like Mexico, Nigeria, Japan, Philippines, Russia, Ukraine, Colombia, Venezuela. It's just not there any more.
Plus I don't know if it's a safe assumption to trust the official WT figures any more. It's true they've been honest about their figures in the past. But frankly it's easy to be honest about growth when things are going well. Will they continue to publish truthful statistics when a clear pattern of decline emerges? It's a situation that hasn't been tested.
Plus there's certainly been inflation of all the measures over the years. Publishers can now count 15 minutes on the ministry. Pioneers dropped from 100, to 90, then to 70 hours. Bible Studies used to be reported only after the second successful study or something like that. Now even a simple "agreement" to a Bible study is reported (if I picked it up right). Plus if each congregation hosts a cart, that's upwards of 300 hours per congregation per month. That's a huge chunk of the global "hours" preaching actually spent standing next to a cart.
The only measure that can't really be inflated, fudged, or falsified is the number of congregations. That's the number to keep an eye on, and it's a figure that is already declining in some countries.
