The increase in age-specific death rates in the younger parts of the population (15 – 54 years old) has been extraordinarily significant – it is above 20%. And one cannot even state the hypothesis (which – even if the numbers fit – would still have to be examined) that this increase is due to COVID-19: Just look at the numbers, the COVID-19 death rates in these age groups are far too small. Something else must have led to this increase in mortality in the younger population.
The conclusion is that the Coronavirus has no influence on the mortality of the 50-70 age groups. And that very conclusion is the same for all groups below 80 years of age. As 80 is the average age of death in the population, the general conclusion therefore is that the Coronavirus has no influence on population mortality.
