ONS deaths data has been released for week ending 23 Dec.

2,982 more deaths were recorded in-week compared to the 2015-19 average. That’s 26% more, the largest excess we’ve seen all year.

Year-to-date there have been 567,379 deaths recorded which is 8% more than 2015-19 avg.
There were 429 deaths in England and Wales this week where COVID was mentioned on the death certificate. The number of COVID deaths increased each week through December.

72% of deaths with COVID mentioned on the death certificate had it listed as underlying cause.
Deaths data was also released today for the previous week (ending 16 Dec).

This showed 1,639 more deaths compared to the 2015-19 average. That’s 15% more, also a bigger excess than we had been seeing.
The data ends just before Xmas so there’s no impact from Bank Hols. We know that COVID and flu were at high levels and there were severe delays in A&E. These are also weeks when nurses (15 and 20) and paramedics (21) were on strike (but note delay between death and registration).
Comparisons of death counts can be distorted by population growth and ageing.

The best way to compare deaths during the pandemic to prior years is to use age-standardised death rates.

The CMI Mortality Monitor takes this approach. Their next update is expected later today.
The CMI age-standardised mortality analysis is now available and shows death rates 18% higher than pre-pandemic this week.
More discussion of the issues here👇
Here’s how yesterday’s ONS deaths data look when we consider (modelled) date of death rather than date the death was registered.

I’ve marked up acute factors on the chart but chronic factors like NHS pressure are there throughout, contributing to continuous excess for 9 months.
Going to be kicking myself all day about “Omicrom” typo (and copy/pasting it repeatedly times”).

Here’s a typo free version (I hope) for anyone who wishes to share it.

I had an extensive and at times provocative discussion with @freddiesayers on the significant excess deaths we’ve seen in recent months.

We discussed what the data shows and the limits of what we can currently say about who is dying and the immediate and underlying causes.
Data from @OHID shows a clear pattern of recent excess mortality in all adult age groups. Cardiovascular, diabetes and urinary diseases stand out as major causes with a significant excess, where acute covid does not seem to be the immediate cause.
Some of the excess deaths are of course caused by acute COVID. Once we age standardise, COVID seems to explain around half the excess in England&Wales and Northern Ireland. It seems to explain all of the excess in Scotland.

ONS deaths data has been released for week ending 26 August.

1,785 more deaths were recorded in-week compared to the 2015-19 average. That’s 19% more.

Year-to-date there have been 374,970 deaths recorded which is 6% more than the 2015-19 average. Image
There were 453 deaths in England and Wales this week where COVID was mentioned on the death certificate. That is a significant fall from last week.

62% of deaths with COVID mentioned on the death certificate had it listed as underlying cause.
So this week continues the recent pattern of abnormally high excess deaths. See my recent @COVID19actuary blog for a discussion of the recent pattern and possible underlying causes. The blog has links to recent media appearances discussing the same.

Are we seeing significant excess deaths in England and Wales at the moment? Yes, absolutely. Death rates have been around 11% above pre-pandemic over the last 8 weeks.

So why might skeptics suggest otherwise? If acting in good faith then they don’t fully understand the data 🧵
There has been a lot of discussion of excess deaths in the last week or so. The issue made the front page of the @Telegraph in an article which (I’d say wrongly) pinned the blame on lockdowns. /2
You might have seen my @UKandEU blog discussing likely causes of the excess deaths.

And unless you were hiding under a rock you’ll have seen an excellent @jburnmurdoch mega-thread on the same topic. /3

This rhetoric is divisive and unhelpful, particularly the headline.

It’s correct to say we are experiencing significant excess deaths. It’s also correct that much of the excess didn’t arise directly from COVID.

But I disagree with calling these deaths “lockdown effects”. 🧵
We have been experiencing significant excess deaths for around three months now, as I have highlighted each week.

Some of the excess is explained by the ageing population, but the CMI’s age-standardised calculation still shows significant excess deaths - over 11,000 this year.
A significant proportion of the age-standardised excess are deaths with COVID.

However, a similar number are not. It is these non-covid deaths that @sarahknapton’s article focuses on, calling them “lockdown effects”. This attribution is speculative and I’d say it’s inaccurate.

ONS deaths data has been released for week ending 5 August.

1,662 more deaths were recorded in-week compared to the 2015-19 average. That’s 18% more.

Year-to-date there have been 342,691 deaths recorded which is 5% more than the 2015-19 average. Image
There were 723 deaths in England and Wales this week where COVID was mentioned on the death certificate. That is a significant fall from last week.

65% of deaths with COVID mentioned on the death certificate had it listed as underlying cause.
So this week’s excess is a little lower than the last two weeks, both of which included additional deaths arising during the heatwave. However 18% is still an extremely high excess, continuing the pattern we’ve seen over the last three months.

A lot of people have asked for a @COVID19actuary view on this thread. I’ll give a personal reply for now, though others I’ve spoken to concur.

Big picture: broad agreement that the recent excess mortality is concerning and we need to better understand root causes. Detail below.
My biggest quibble is around the size of the excess. Yes, @ONS shows 1,034 excess deaths a week in Eng&Wal over the last 11 weeks. However, after age-standardising, around half the excess goes away.

CMI analysis shows 486 excess deaths a week over the same period.
I should note that the @OHID data which @dgurdasani1 also refers to also allows for changes to the population structure. I haven’t looked at that approach in detail. The OHID data is a couple of weeks behind but gives an average excess between the ONS and CMI numbers.
