I'm really not even paying much attention to the numbers anymore; I'm just going by the general, overall pulse/feel/look/"smell"/etc.
JWdom is dying. It is weak. It is floundering. The org used to be proactive; it is now only reactive. It is simply in survival mode... flapping at the water trying to keep from drowning. It used to be analytical and would focus on doctrine and prophecy; it can no longer do that because the internet has exposed it and equipped others to counter it. Back in my zealous days, a lot of JWs almost relished challenges, deep questions, and arguments; now they run from such and don't even know their own doctrine.
A couple of years ago, a 35ish female JW approached me in a parking lot and tried to give me a tract. I didn't make it easy on her and tried to talk with her. I found out that she had never even heard of Fred Franz. That is inconceivable to me. He was one of the most influential figures in JW history; he was their one and only guru for many years, and she had never even heard of him. When her partner (parked in an SUV nearby) saw that I wasn't low-hanging fruit, she started calling for the lady to come join her (and leave me).
The old JWdom is dead. This new thing is a shallow, "plastic", dumbed down, televangelist-like, embarrassing, shiny & glittery, cult which has become a social club as compared to the somewhat analytical, seemingly scholarly religion it used to be.
I have mentioned this a number of times, but I see benefit in mentioning it again. Back in around the '80's, just in my area alone, there were eight engineers, two dentists, a veterinarian, an attorney, two medical doctors, a college professor with a doctorate, a high school teacher with a BS in physics, a brilliant armed forces pilot, a number of smart businessmen, and a number of deep-thinking hippies who became JWs. And these are just ones I'm aware of; I don't even know who became JWs in a nearby huge city. That will never happen again! Gone are the days when JWdom will appeal to such types.
The ones referred to in the previous paragraph studied, researched, questioned, analyzed, thought deeply. Such is virtually disallowed now in JW land, because the leaders know their theology and history can't stand up to such.
So, the numbers don't tell the whole story, and I really don't even trust them. I do like seeing reports and analyzing the numbers, but I put more emphasis on the general appearance. I do believe we're going to start seeing a decline in numbers in the relatively near future. If JWdom does continue to grow, though, it will be due to born-ins and low caliber types from the outside (the unstable, the needy, the lonely, those on the low end of the intelligence spectrum, etc.).
