You don't care how they did you literally just applauded them.
Here I'll do it for you. Triple the deaths of Norway, 6 times the deaths of Finland, 10 times the deaths of Norway and Iceland it's obscene how much higher it is but Iceland has a really tiny population. . But I digress. None of the Countries but Iceland have less than half the population fo Sweden. To add a feather to Denmark's cap they have 5 times the population density of Sweden.
And before you talk about Population Density of cities, Stockholm is the 7th most densely populated Nordic city. Copenhagen is both a bigger population and higher density.
Alright but let's talk about economy. There's no major difference in GDP from any of them.
