In our local congregation there are around 50 in the hall and 15 or so online. This compares with usual attendances of around 50 to 60 before the pandemic. Is that down or up? It’s pretty much the same.
Last year’s summer convention in Glasgow had between 7000 and 8000 in attendance. This is similar to figures stretching back as far as I can remember. On that measure attendance has been pretty flat for around 30 years. I don’t see any major moves, up or down.
One thing that has changed is there are more foreign language congregations however, especially Polish in Scotland. So overall the number of active JWs is probably slightly up when you take that into consideration.
By contrast most other churches are declining rapidly, including the Catholic Church which also benefitted from an influx of polish Catholics in the early 2000s.
