Looking at this chart I can't help but notice that pre-1984 the growth statistics were extremely erratic. Then, all of the sudden in 1984 the growth statistics calmed down and have ever since fallowed a much more stable trend. It's almost a straight line after 1984.
So what happened? What changed? Did the WTS growth stabilized after the Governing Body took over? Organizations that are controlled by committee tend to be far more stable than organizations controlled by a single charismatic leader.
Does anyone know precisely when the Governing Body came into power?
Does anyone have any other theories as to why the WTS's growth rate would stabilize in 1984?
