It looks like Jehovah’s Witnesses, Baptists, and Seventh-day Adventists are the only Christian groups to have increased between 2016 and 2021, and JWs have the largest percentage increase of the three.
Anglicans, Catholics, Churches of Christ, Later Day Saints, Lutherans, Eastern Orthodox, Pentecostals, Presbyterians, Salvationist Army and Uniting Church all declined between 2016 and 2021.
Jehovah’s Witnesses increased by 2.3% between 2016 and 2021, whereas Mormons decreased by 6%.
Jehovah’s Witnesses, despite all their problems, and the Royal Commission in Australia, continue to outperform other religious groups. Why is that?
