Since the pandemic began I worked with the assumption that it is about 1% (or with some fuzziness depending on uncertainties and social factors: 0.5 to 2%), based on the reported CFRs in specific outbreaks and knowing roughly the fraction of asymptomatic cases. Then the antibody studies in New York supported that (not less than 0.5%).
That figure varies significantly between countries. The differences could be real (due to healthcare, lifestyles, genes, population distribution, etc), or the methods for estimating could differ, or a combination. The Norwegian Institute of Public Health has published a risk assessment
with the following mortality rates by age:
All ages: 0.12%
80+: 4.0 %
That easily explains the negative excess deaths. In the 80+ group there are likely a few percent very frail people near death anyway, and without the flu threat many have lived an extra year.
