Like I said in my post the 4 million number is just my opinion but I base it on observation. It pretty common that cults inflate their numbers. But just look at the year books the only real thing we have to go on. Every year they show publishers and now just count the peek number which we know is bullshit. Also the Baptisted number looks as though it’s added to the publisher number the year they get baptized but the newly baptized one has already been counted as a publisher.
Then consider how many leave, 60 to 70 % of the young ones leave many never even getting baptized. That’s what happen in my hall with my peers and again with my sisters group 15 years younger. So the numbers are smoke and mirrors , more proof is the 3000 + halls their selling off more proof they don’t have the numbers.
So with that said that’s how I come up with the roughly 4 million mark. Just remember we can’t trust watchtower on their biblical teachings and we know they lie about what’s scholars have said also lie about other things so why would we not think their lying about their membership numbers ?!
