On threads about 8 or 9 months ago, I put up some detailed data from the 2011 and 2006 Australian censuses. Data from the 2016 census is becoming available in stages, and I mentioned recently that I would do an update. Finally, as of about today, some data of interest is available, and I have started to look at this, but it is time consuming, and I am time-poor.
Anyway, the first search I have conducted is just a simple breakdown of the number of People describing themselves as JW's. Here are the results, for each of the last 3 censuses:
Year 2006 (when Watchtower Yearbook reported 60,022 av pubs): 80,918
Year 2011 (when Watchtower Yearbook reported 64,498 av pubs): 85,498
Year 2016 (when Watchtower Yearbook reported 66,689 av pubs): 82,512
Just to repeat what I said in an earlier post, e census numbers are always going to be larger than the Yearbook number, because the census numbers include kids in the same household. Eg, the 2011 census listed 5,162 JW's aged 10 to 14, 4,857 aged 5 to 9, and 4,538 aged 0 to 4.
I couldn't initially believe the data for 2016, but I extracted it two separate ways, and repeated it for each census database in the same manner. I also extracted a breakdown by gender, which gave for the 2016 census: 35,913 male and 46,600 female (totalling 82,513).
So from 2011 to 2016, when Aust population grew by about 7 or 8%, average publishers increased by 3.4%, the number of people who stated they were JW's on the census DECREASED by 3.5%.
