In North America & Europe, in general, convention attendance can be a little tricky to analyze. Lots of people go to multiple conventions, others go to one where they are not assigned...in most place which are at least moderately populated, there are usually multiple venues within a 2-3 hours drive, and 3, 4, maybe 5 convention weekends to choose from.
Picking just one convention in isolation, it can be hard to to gauge the level of interest just by looking at attendance numbers.
And yet.....
I don't want to go into too much detail, but I live in western Europe. Due to a special combination of geography, language, and economics, I live in an area where the idea of "well, if I can't go to XYZ convention, I'll just go to this other city this other weekend" doesn't work, at all.
So, one can gain a little better insight by analyzing attendance at this one convention in isolation.
At the recent regional convention, attendance topped out Sunday afternoon at about 2900.
Pre-pandemic, Sunday attendance was usually around 3500.
In other words: taking this convention where JWs have no real "Plan B" - it's attend this one, or stay home, for the most part - attendance dropped nearly 20% from 4 years ago.
Think about it: The first in-person convention in 4 years. We had Mark Sandwichson on a GB update exhorting the R&F to attend the convention. It was supposed to be a big deal.
And a huge chunk of the JW population just said, "meh, I'll just stay home, maybe catch it on streaming".
I think the WTS has lost the "weak ones". They're just gone - they may still be "active publishers", they still may attend meetings (mostly on zoom), but if they can't even muster up the enthusiasm to attend a convention for the first time in 4 years....they're pretty much over it.
Now, it's the guys who used to be "middle of the pack" who are the "weak ones". Before too much longer, they'll start drifting away too.
The WTS is slowly deflating.
