Did you mean to link to some other data? This list shows that the Nordic state with the highest suicide rate is Finland at number 38, in which suicides are about 30% higher than the European average (although of course Greenland remains an interesting artefact). I don't think that really fits your description.

It's always been pretty interesting (and I'd say quite well-known) that the Nordics do have a somewhat higher suicide rate than other similar states. But it's also likely a pretty bad proxy; I'd be suspicious of a metric suggesting the average North Korean citizen is substantially happier than the average Finn.

Probably better is the World Happiness Report (https://worldhappiness.report/ed/2020/social-environments-fo...). It's a bit arbitrary for my taste, but does at least have a pretty long history as well as plenty of transparency about what it's measuring and why. And it consistently places the Nordics in the top ten.
