I thnk the reduction in hours for a pioneer is a massive reason why there are many more now. I'm not sure what the reg hours are now, I think it's 60? That a massive difference from 90 when you are also trying to earn a living at the same time.
i know the cong I was part of in Scotland years ago has decreased. I am very good friends with an ex elder who left just 2 years ago, he was telling me when he was an elder in 2011 there were only 3 elders in the hall. There was something like 15 when I was there.
Figures are deceiving. Whether there are more jw's now, less, more or less elders, more or less pioneers, what difference does it make? It could increase 10 fold and it wouldn't be any more true than it is today. Something is still false whether 10 believe it or 10 million.
