After quickly analyzing the most developed countries (HDI >0,8), I noticed that grouping countries according to some culture related patterns is quite easy. More analysis should be done (by someone else), but seems, that suicides have more to do with culture than development. Some cultures are able to handle development better, some – worse.
What: Suicide rate vs human development index
When: Suicide rate – 2016, HDI – 2017
Where: Countries with HDI > 0,8
Source: Suicide rate – WHO, HDI – UNDP
