Thank you shepherdless, this is excellent information. 👍
I wonder, do you have access to the figures for the very small groups: Christadelphians and Unitarians? Because I have a particular interest in these groups, and the data is not available on Wikipedia.
I am all in favour of comparisons between groups, because I think it’s a major way we can make sense of trends and the significance of various factors affecting growth. It’s fair to point to the pandemic as having a major impact, for example, and at the same time all religious groups experienced the pandemic. So if some groups declined and others grew during the pandemic, then we need to expand on the relevance of the pandemic as an explanation for a particular trend in a particular group.
According to the data for 2021 and 2016 for religious groups in Australia, this is how JW growth compares with other Christian groups:
Anglican - 19.5%
Baptist + 0.6%
Catholic - 4.1%
Churches of Christ - 9.3%
Jehovah’s witnesses + 2.3%
Latter Day Saints - 6%
Lutheran - 16%
Eastern Orthodox - 8.1%
Pentecostal - 0.3%
Presbyterian and Reformed - 21.2%
Salvation Army - 27.6%
Seventh-day Adventist + 1.3%
Uniting Church - 22.6%
So Jehovah’s Witnesses are the fastest growing Christian group at + 2.3%, followed by Seventh-day Adventists at + 1.3%, and Baptists at + 0.6%
The other Christian groups have all declined, some, including the Uniting Church, Lutheran, Presbyterian and Reformed, and Anglican by around a fifth, or 20%. The steepest decline was in the Salvationists at - 27.6%.
These figures are similar to trends in the UK. Over the year 2021, for example, the Church of Scotland lost over 5% of its membership. Other churches are similar. The only groups I have observed showing signs of growth during the pandemic are JWs and SDAs.
