Interesting...Memorial attendance really hasn't changed much in 17 years. It was 27K (and change) last year...and the same in 1998. Meanwhile, the population of NZ has grown by 1 million in that same period (26%).
The 2017 "Ratio 1 publisher to..." has slowly increased to 1:340 in 2017-- the worst ratio in NZ since 1986...31 years. Clearly the efforts of JWs in NZ to even keep up with population growth has stalled.
"Peak publishers" has basically stayed flat, only fluctuating within a small margin since 2008...nearly 10 years.
