I can believe the numbers - we hardly ever see people out in service round here and when we do it's usually a pair of die-hards on their own.
One thing that puzzles me though: didn't the WT make a 'thing' out of the fact that they only count those who preach as members? So if they are not going out preaching then how can they have any % that are inactive? (if that makes sense!) Surely they should just have a lower number of members ... unless, of course, that admitting it would *really* hurt!
Keep massaging your figures WT
