Cofty,
Is that correct, that excess deaths are 31% above average in the UK week after week after week? I'm not that good on understanding the statistics shown on the link you gave. But it looks to me that the week in question was
''Expected'' registered deaths based on week 16 of 2019 was 9,484. (Quotation marks are from the link)
Excess deaths (and as a percentage of expected) 2.936 (31%)
But comparing week 15 of 2023 with week 15 of 2019 it was a drop of 8%.
