You can only die once. The flu season in 2019 was very mild, which meant more people than normal survived to die in 2020.
The ONS reported that the total number of deaths in England and Wales was 506,790 in 2013, 501,424 in 2014, 529,655 in 2015, 525,048 in 2016, 533,253 in 2017, 541,589 in 2018, 530,841 in 2019 and 608,00 in 2020.
Much more important than these numbers is the fact that the 'age-standardised mortality rate' (adjusted for changes in both the size and structure of the population) in 2020 was the highest since 2008.
It was no higher than any of the years before 2008. The death rate in England and Wales in 2020 was lower than in the early 2000s.
Without lockdown another 97,000 would have died from Covid-19 this winter alone, according to a government estimate, but that is of course a guess. It can't be known what would have happened has looser restrictions been tried.
Estimates and modelling are one thing but there should be evidence by now after ten months of the pandemic - there should be an obvious reduction in deaths in places with lockdowns compared to places without a lockdown, but there isn't.
Peru has had the harshest, longest lockdown and has the highest death rate per capita in Latin America.
Romania had no lockdown after May and Covid deaths have been falling to the extent that they have reopened restaurants.
Belarus lied about the number of deaths and the real numbers were three times what the government said. Still, despite no restrictions of any sort, the number of deaths per capita in Belarus is no worse than with a bad flu season.
The report also says that more than 100,000 people are likely to die from non-coronavirus causes because of the pandemic. 40,000 may die over the coming years because of the economic consequences of the lockdowns. Again it's a guess.
I know don't know the figures for all of Europe but Swedish deaths in 2020 were about the same as in 2000-2003 and about 2.5% higher than 2018, despite not having a lockdown.
Two thirds of Covid-related deaths in Sweden three or four months ago had occurred in old people's homes and the average age of death was 84. Three quarters of Covid-related deaths, where Covid was mentioned on the death certificate, in old people's homes in one Swedish province were not in fact deaths from Covid.
