Short answer?
Because the population was ageing in that period. It's DEMOGRAPHY!
I'm a big fan of @dannydorling but he's got this one wrong.
As @ActuaryByDay will tell you, once you age adjust the death rates you'll see they kept falling from 2012 to 2019. This is important.
Here are some charts that illustrate the point.
First off is simple deaths per year (England & Wales).
Yes, deaths crept up post 2010, reversing a long trend of falls.
But now recall that a) the population is ageing and b) these demographic trends matter enormously
More old people in a bigger population means, all else equal, that deaths will tend to rise each year. Because older people are more likely to die than younger people. That's why actuaries age adjust their data. And if you age adjust the data here's what it looks like:
Now it's certainly true that the rate at which mortality rates decreased slowed somewhat post 2010. It's plausible that austerity played a part in this. But saying mortality dropped but slightly less quickly than in previous years is v v different from saying it rose!

Thread: Since the UK has just released its latest data on greenhouse gas emissions, this feels like as good a time as any to look at the numbers and ask: what’s really going on? The broad picture is v promising (see these headlines from earlier): emissions falling fast.
Before we go any further, this is not a thread about “the science”. It’s not a debate abt climate change. Feel free to debate that elsewhere. This is abt the DATA. And while there are some interesting question marks over the data, the overarching aim of govt right now is v simple
The UK has committed, in law, to get greenhouse gas emissions down to zero in net terms by 2050. If you consider the starting point for that effort to be 1990, it’s now nearly (but not quite) halfway there. This is quite something…

Since it’s a year on from lockdown and the second wave of excess mortality now seems to be over, a few datapoints on #COVID19 mortality in the UK.
Starting with this: we’re now at 149k deaths according to the @ONS measure (deaths where COVID mentioned on certificate)
Important to note this isn’t the only measure though: excess deaths, which is deaths from ALL causes vs 5yr historical average, puts the toll at 123k. We’ll get to why there’s a big difference in a moment. Even so: however you measure it we’re talking about high numbers of deaths
Strikingly, on the basis of the most comprehensive @ONS #COVID19 figures, total #COVID19 deaths (149k in total). The second wave was far bigger than the first wave. 91k in the latest wave vs 58k in the first.

Something to ponder as you fill in the census. We’re currently in the midst of the most dramatic fall in the UK population since 1941, as three forces collide to push down the number of people living in this country news.sky.com/story/the-thre…
Incidentally a few people have understandably asked whether the fall in migrants last year might have been a Brexit effect. But while this might have contributed at the margin it doesn’t seem to be the main explanation. Anyway, the exodus was both EU and non-EU workers
That last chart is from this piece migrationobservatory.ox.ac.uk/resources/comm…. The phenomenon of enormous migrant outflows was first pointed out by @StrongerInNos and @jdportes ukandeu.ac.uk/estimating-the…

One year on, how big a deal was the furlough scheme? Short answer: a v v v big deal.
I think we sometimes underplay this.
It has pervaded our lives in a way few if any other economic policies have and had all sorts of unintended consequences - good & bad. thetimes.co.uk/article/d724c3…
Comparable data on this isn’t especially easy to come by but the last time the @OECD had a look (turn of the year), UK had more people on furlough than any other country. Think about that for a second. And note we didn’t have either the most cases or toughest lockdown back then
When you think about it it’s pretty remarkable. Britain was unusual in Europe in not having a job retention programme (short time working) before #COVID19. But the generosity of the furlough scheme, and the enthusiasm with which it was taken up exceeded most of Europe.

New: according to the @ONS the total UK #COVID19 death toll has now surpassed 125k.
Was 126,023 as of 29 Jan.
Note these are deaths where #COVID19 was mentioned on the certificate. Of those deaths, around 91% were caused by #COVID19, according to the @ONS.
Another way of calculating the death toll is excess deaths, which is deaths from all causes vs the five year average.
This was 111,540 across the UK between March 2020 and late Jan 2021.
Total deaths from all causes in week 4 of 2020 (the latest week) were higher than in the corresponding week of ANY year going back to 1970.
That’s still true even after adjusting for population.
31 deaths per 100k in week 4
Previous worst week 4: 28 per 100k in 1985

I’m dearly hoping govt releases some actual data on the lethality of the new variant.
Holding a press conference to announce this ominous news alongside vague caveats about uncertainty is not a functional way to share this news
Nor was leaking it to journalists ahead of the event
There’s an irony here: @uksciencechief just told us to be a bit wary of the reports coming out of Israel warning abt the efficacy of single dose #COVID19 vaccines.
Why? Because of a lack of data.
Yet here he is making equally significant claims without providing the data.
Argh!
This episode underlines a deeper problem: a culture of data secrecy in Whitehall & NHS.
There are vast datasets that are never publicly released. Sometimes secrecy is justified to protect privacy.
Rest of the time there’s no justification for it.
This is public data. OUR data.
