We know cremation rates are changing and have been increasing for decades, and this is supported in a recent report on Observations from the British Islands.
One of the most stark changes is in the Disposition of Cremated Remains, in 1970, 69% were strewn in the crematorium grounds, but in 2019 it was only 15%.
Similarly in 1970, 14.5% of cremated remains were interred at the crematorium, but in 2019 only 4.5% were. In 2019, 80% of cremated remains were removed from the crematorium compared to only 12.5% in 1970.
