THREAD – Mortality 2020

Today we published England & Wales mortality statistics for the w/e 25 Dec

Nearly a full year’s data for 2020

In the last 52 weeks there were:
c.604k deaths registered across E&W

This is:
c.73k deaths (14%) above the 5-yr avg = excess deaths

1/11
Remember the bank holiday effect which affects weekly figs

And the lag between deaths occurring and being registered

We now provide modelled estimates of death occurrences to remove these

The chart below shows both registrations and modelled occurrences across 2020

2/11 Image
Looking at excess deaths, we began the year with death levels below the 5-yr avg

This was followed by a huge peak in the spring, driven by COVID, until lockdown1 took effect

Note the small Aug heatwave peak

And then a gradual pick up through autumn as CV took hold again

3/11 Image
A seasonal effect means more deaths in winter than summer

The pattern of excess deaths as a % of normal weekly deaths is similar

There is a noticeable jump in the latest w/e 25 Dec

Given the recent alarming rise in CV infections this will increase further in Jan

4/11 Image
For longer term context we can compare annual deaths back to 1900

Deaths have been rising recently as life expectancy improvements have stalled, but the jump this year to over 600k is clear

Only one previous year has topped 600k – 1918, the year of the “Spanish” flu

5/11 Image
Numbers of deaths are affected by population size

We can also consider death rates – as a proportion of the population

“Crude” death rates are shown below

All improvements in the first decade of this century will be reversed this year

“Spanish” flu did the same in 1918

6/11 Image
Numbers of deaths are also affected by population structure, such as age. We will produce age standardised rates soon

Whilst the UK-born population is ageing, with post-war baby boomers now in their 50’s to 70’s, recent immigration will have predominantly been younger

7/11
Our world changes too

Medical advances, the NHS, welfare state, better living conditions, all mean that 14% of babies do not die before their 1st birthday. They did in 1900

Excess deaths vs the last 5 years gives current context

This year will see the most since 1940

8/11 Image
We can adjust by population to get crude excess death rates

2020 will also be the highest since 1940

Even with measures taken to limit COVID spread, 2020 will still top 1951, the year of a major flu epidemic

Without all our efforts, 2020 could have been much worse

A week is a long time in a pandemic

But the basic COVID logic remains the same 👇

Thank you to everyone caring for the sick in such difficult circumstances, you are heroes

My deepest condolences to all who have lost loved ones this year

10/11

Thread on today’s figures from the main ONS account below 👇

Best wishes to all suffering with COVID today

And best wishes for an eventual recovery to all of you with Long COVID – I know how you feel

Stay safe and keep others safe

11/11 - ENDS

THREAD – “The death rate from COVID is only 0.1%” – Oh no it isn’t

I won’t name and shame, but this fake stat also seems to have been sold to some people. Buyer beware

In what is starting to feel like an advent calendar of fact checking, let’s let in some light…

1/4
This one is simple

Even a basic calculation shows that the death rate must be much higher than 0.1%

With c.65k people having sadly died *from* CV across England & Wales, that would mean 65M had already caught it

There are only 60M of us here

It’s still spreading

2/4
Death registrations have nothing to do with any 28-day cut-off period

A fatal car accident is a fatal car accident

Doctors across the country are not all conspiring to put CV on death certificates

If only we could trace the sources of this stuff 🤔

THREAD – mortality rates

The linked thread addressed fake ONS stats that were circulating

As I made clear in the final tweet, the number of deaths is affected by population size/structure and much more

Thanks for the comments. Some thoughts on rates and context…

1/11
The very best place to start for full context is this report on how our population has changed since 1900

Our population – Where are we? How did we get here? Where are we going?

ons.gov.uk/peoplepopulati…

I co-authored it and we published in Mar, which seems a lifetime ago

2/11
Although the no. of deaths registered this year will be similar to 1918, the population is much different – bigger and older

The country is totally different too. Better sanitation & living conditions, antibiotics & universal healthcare, welfare support etc etc

THREAD – statistical misrepresentation

I have seen the table below being widely shared to falsely imply that deaths are no higher than normal this year

The table is both factually incorrect and misleading

Those who created it deliberately sow confusion and doubt

1/6
Firstly, a common approach used to manipulate statistics is the selective use of dates or time periods

In the table you can see that previous complete years are being compared to a partial year – only going up to week 45 of this year, which ended on 6 Nov

2/6
Secondly, having made it look like official numbers are being used, the wrong number is actually given

There had been 517k deaths registered by 6 Nov this year, not the 485k that are stated in the table

THREAD – COVID local area and deprivation analysis

Today we have updated our spatial analysis to include all deaths registered and processed so far that occurred from Mar-May

Our interactive local level MSOA map can be found here:

ons.gov.uk/peoplepopulati…

1/n
An updated interactive Local Authority map is in section 4 (fig.4) of our report:

ons.gov.uk/peoplepopulati…

For both the MSOA and LA maps you can select areas, months, and whether to include all deaths that occurred or only those where COVID was mentioned on death certs

2/n
London had the highest COVID-related age-standardised mortality rate (ASMR) with 137.6 deaths per 100k persons (Mar-May)

This was significantly higher than any other region in Eng and more than a third higher than the region with the next highest rate (the NW)

THREAD – Deaths registered w/e 29 May (E&W)

This was another bank holiday (Mon 25 May) affected week

As a result, we expected to see a reduction in the number of deaths registered. We also hoped to see a drop in the % that deaths remained above the 5-yr weekly average

1/n
There were 9,824 deaths registered, 20% fewer than the week before

This was 1,653 “excess” deaths above the 5-yr weekly average

= 20% above what we’d expect in this week of the year, down from 24% above the week before

2/n
1,822 deaths mentioned COVID on death certificates, 19% of all deaths registered

As in the week before, this was 110% of the number of excess deaths i.e. slightly more

Deaths not mentioning COVID on death certs were slightly below the 5-yr weekly average

THREAD – “Non-COVID” excess deaths

Between 7 Mar & 1 May there were 130k deaths registered across E&W

This was 46.4k deaths above 5-yr averages

According to death certs 12.9k (28%) of this “excess” did not mention COVID

98% are now fully coded enabling detailed analysis

1/n
Possible explanations include:

1. COVID was present but undiagnosed, particularly in the presence of other co-morbidities and the absence of a positive test

2. Reluctance to seek care or a delay in receiving care for people with serious health conditions

2/n
3. Reduced hospital capacity affecting ongoing care for people with underlying conditions

4. An increase in stress related causes due to lockdown

5. An increase in death registration efficiency introducing a process effect
