According to this article Greenland is the country with the world's highest suicide rate. From 1900-1930 Greenland had a suicide rate of 0.3 per 100,000. Now it's a staggering 100 in 100,000 and is the highest in the world! Why such a huge increase? In the first half of the 20th Century they lived much as they had for the past 4000 years-- namely hunting and fishing and living in small villages. So perhaps something to do with the change in the way they live?
suspect people are happier in small closely knit communities with a
shared history and identity, where everyone knows each other, and where
they do traditional work rather than doing repetitious work for some
faceless company in the modern world. I would speculate the modern
world, and the style of living it inaugurated, has some role to play in
why so many people are depressed and commit suicide.
