It's proportional. The excess mortality increases by ~10% across the board but the base mortality rate for younger demographics is much lower.

I made this table: https://imgur.com/PZqKWk2

It shows the point melolife made, that the percent excess (excess deaths as percent of expected) can be high, but the expected number is fairly low, so the total number of deaths is still relatively small.

The data is from November 9, so not up to date.

The excess mortality in the United States doesn't make any sense at all. I followed the link to the article that contained the data regarding the United States, however it was an article that only dealt with the Eurozone and made no mention of "us" "united" "the united states" "America" or "usa" anywhere in the article, so I'm not really sure what evidence supports their claims about the USA?

I can't answer your question, but I do happen to know that there has been a large increase in drug overdoses and suicides according to the data I've seen for a specific region I was looking at recently. No idea if it's a national trend.

> All the previous findings were that

That was first wave data. Second wave data has shown that the risk for younger people is higher than we thought.

I don't think this explains all that increase though.

As early as Spring last year, mortality increase was estimated to be about the same for all age groups.
