There has been a recent study comparing mortality in Sweden and Norway which is much more sophisticated than the simplistic Sweden-bashing comparisons that are often made.

It looks like mortality has generally been higher in Sweden, not just this year: 'Our study shows that although Covid-19 associated mortality rate was almost 15-fold higher in Sweden than in Norway during the epidemic, all-cause mortality was not higher in Sweden compared with three of the four preceding years.'

They maintain that excess mortality in Sweden was concentrated into the first epidemic wave from the surrounding periods, which were lower, a type of 'displacement'.
