On the one hand , if their is a disaster , a natural occurrence such as an earthquake , tsunami , tornadoes etc, the witness Armageddon barometer kicks in .Many fence sitters , relatives etc. flock to the nearest K.H. for a time.
On the other hand ,
Because of the information that is now available on the internet ,Child abuse scandals ,Govt. investigations /Charitable status ,questions many people are leaving the organization .
It`s a to & fro motion that goes on .in a never ending cycle .
Disasters happen an influx in numbers proving Jehovah`s blessing
Bad publicity a decrease in numbers proves Bible is true
When the increase occurs its because of Jehovah`s blessing his one true religion
When a decrease occurs it`s fulfilling scripture prophecy " In the last days the love of the greater number will cool off "
So the J.W.`s have an each way bet on whatever happens
How do you reason with that kind of logic.?
So I think they will still be around for a long time yet .
