Don't wish to float a turd in the punchbowl, but this could start to sound like the longtime JW rant about how the churches are losing members at a staggering rate and then citing a church that closed somewhere as proof. The problem with that logic is, there's always another church somewhere that has grown from 0 to 5,000 members in 10 years!
The truth is, congregations come in all sizes. Much depends on the area and the rate of population growth (or decline). I went to one not long ago that had 195 in attendance, and it wasn't even the CO visit. Another congo in a very small hall had standing room only when I went to give a talk. Turned out I was not the attraction, after all, but rather the KH was in a small resort area and at that time of year there were dozens of JW "snowbirds" staying in nearby campgrounds and trailer parks and they packed out the hall for a couple of months every winter.
On the other hand, another meeting we attended had 54 people one Sunday, a poor but typical showing even for a small congo of some 85 pubs. Two years earlier, that congo had over 130 pubs, so a trend is under way at that location.
Overall, there does appear to be an emerging trend in favor of shrinking attendance. All of us "old timers" can remember when missing a meeting was a big deal; today, it's much more common.
