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

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

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

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

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

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

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

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

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

UPDATE – Mortality 2020
Yesterday we published the last week of Eng & Wales death registration stats for 2020
There were c.608k deaths registered across the full calendar year (1 Jan - 31 Dec)
My colleague Sarah’s blog puts these figures into context https://twitter.com/ONSfocus/status/1348946050875355136

My colleague Sarah’s blog puts these figures into context https://twitter.com/ONSfocus/status/1348946050875355136
The blog also gives the provisional age-standardised mortality rate (ASMR) for 2020
= 1043.5 per 100k
This was c.13% higher than the ASMR for 2019
And c.8% higher than the recent 5-yr average ASMR
We have annual ASMRs published back to 1994 – charted here
= 1043.5 per 100k
This was c.13% higher than the ASMR for 2019
And c.8% higher than the recent 5-yr average ASMR
We have annual ASMRs published back to 1994 – charted here
We can therefore look at annual change against the 5-yr average ASMR back to 1999, as in the chart shown here
The long-run trend is one of improvements driven by better healthcare, public health, the way we live, less risky occupations etc

Although we do not have ASMRs back further than 1994, @EdConwaySky’s thread on Monday had calculations provided by @ActuaryByDay and colleagues
Note the next tweet in his thread shows year-on-year change, not vs 5-yr avg https://twitter.com/EdConwaySky/status/1348708802716196864

All our data for 2020 is still provisional, subject to final cross-checks and QA
Comprehensive annual analysis will be provided later this year
Next Tuesday will see the first release of weekly data from 2021 registrations
Please stay safe
