sir82 a key trend that indicates decline is imminent is the fall in baptisms. There are not enough new JWs to replace those who dying, leaving or excluded.
It's true that, in absolute terms, baptism numbers have only declined a little. But in relative terms baptisms are at an all time low and falling. See the "baptisms as a percentage of publishers" graph on Paul's site.

In addition, a weird bump in publishers in the Congo inflated numbers last year. They can't count on that again next year. That's why I think it could easily be close to zero growth within a couple of years.
