Several years ago, the congregation average was about 120+. Memorial attendance at one point was getting close to the 200 mark with many having to stand as there were no seats left. It was decided that because Jehovah was 'speeding it up', the congregations had to be split in two in preparation for all the newbies that were going to be coming in. Didn't quite work out that way. Within 3 years, so many had either quit going or had moved, that there were no more than 40 or 50 in each congregation, so they put the congregations back together. Last year at the Memorial, I was shocked to see that the Hall was only 3/4 full. I think there was about 125 there.
What I think they find really embarassing is the fact that all the churches in this area are filled to capacity on Sundays. Doesn't seem quite fair to JWs that they spend tens of thousands of hours in Field Serve-Us every year, and they have fewer attendees than what Babylon the Great does.
