The suicide rates by ethnicity are very interesting as well - white people have a significantly higher suicide rate (2x) than most other ethnicity, despite presumably facing fewer problems overall.
My theory is that they can't attribute issues in their life to things like racism/discrimination, so they perceive failures in their own life as their own fault rather than the fault of a racist society. That also seems to fit with suicides dropping during the world wars, when there is something else which you can blame for your problems, suicide rates are lower. I have nothing to back this up though so idk but it makes sense to me, blaming someone else for your situation is a common way to make yourself feel better about it (and is reasonable in many cases I think, there are lots of things you can't control which contribute to failures in your life).
