Especially as there's been a provable drop in other deaths from the self isolation tactics, less car journeys, less car crashes, far better hygiene, less flu and other transmitable disease deaths etc...Have a like for the general sentiments but as far as those casualty figures go, nationally they will be a statistical blip. Average UK deaths each year are around 600k. When you factor in that a lot of the COVID-19 deaths would be likely to die relatively soon anyway the number of deaths afterwards will probably experience a significant drop.
It will be important but in terms of long-term population change it probably won't make much of a difference in a decade.
