The socioeconomic group that had the most deaths were people of foreign background aged 65 or more. Maybe Sweden just has a proportionally larger group of those?

Covid deaths aren't the same as "excess deaths". It's just one of many causes of deaths over a year. Excess deaths is the difference between expected (typically an average of the past 5 years) and actual number of deaths in a year. IOW, due to the circumstances, excess deaths can be 0 despite Covid deaths being > 0.

Just so we are clear. You're saying that if Covid didn't kill anybody, Sweden would have seen [1] 97k - 14k == 83k deaths in the year of 2020?

I am not sure what parts of my post you have issues with.

One good source of excess mortality data for a large part of Europe (plus Israel for some reason) is at https://euromomo.eu/graphs-and-maps/, which also groups data by age in addition to country.

It may come as a surprise that, in the area covered by this source, excess mortality for children age 0-14 was actually negative in 2020.
