What I see here where I am, the local congregations (two congos, different languages) have been shrinking, so an attendance of 60 at the meeting would be 100% if that's all the publishers you have. (Do they still calculate it that way?)
After combining congregations the attendance is still only at 80-85, so I'm thinking a few people took the opportunity to fade. (Smart!) Several just call in, and their numbers are included in those figures.
Fifteen years ago, meeting attendance here would almost always be over 100% - say 120 plus people at the Sunday meeting, and that's just for the English speaking congregation, which had around 95 publishers.
