I can extrapolate.
*** w94 4/1 p. 16 par. 8 Are You Resisting the Spirit of the World? ***
"each year about 40,000 individuals are disfellowshipped from Jehovah’s organization"
So in 1994 40,000 out of 4.5 million average publishers. This is 0.9%
Applying that percentage to today's 7.9 million publishers = 71,000 per year.
Add to this the death rate which in 2014 was about 0.8% globally.
Applying that percentage to today's 7.9 million publishers = 63,000 per year.
On top of this there are those who just leave.
Very broad estimates!
Regarding the CD-ROM, one was released last year and I've not heard that it is discontinued just yet.
I think it is inevitable that it will be stopped in favour of the JW website, however.
