Assuming that COVID deaths are fully accounted for, that would mean about 200k excess deaths due to other, presumably COVID related, factors (suicide, drug overdose, ...).

That's a big assumption though. Some places had death rates decline for many 'normal' causes of death.

Suicide, flu and car crashes caused less deaths than usual where I am, and the lockdowns led a negative value for 'excess deaths'. I'm in New Zealand.
