Do you think it's normal or expected? If so, why?

Precisely, I don't know. I would not expect such a specific group, or any other, to significantly differ (might be a sampling issue, or something with a reason). Hence my question, but that may also be a translation issue.

One could form hypotheses of course, but they won't be much of relevance here I think :)

> Precisely, I don't know. I would not expect such a specific group, or any other, to significantly differ

Do you mean for this specific item or in general? The former makes sense, but the latter I'd find a little weird given how publically well-known it is that there are group differences (take educational attainment in the United States for example).

Yes. A lot of depression about the world is driven by left wing views. Women are more left wing than men, liberals are obviously more left wing than conservatives, and young people are more left wing than older people. So being young liberal and female is the intersection of all those categories.

I don't know how important being white is there, but I also don't see much discussion of race in this line of articles, only gender geography age and politics.

Especially because left/right dichotomy smells particularly anecdotal here.

The article and related articles in the series are a pretty good place to start! They're laying down a lot of rigorous evidence that depression is strongly clustered in the most left wing segments of the population.

Now correlation isn't causation, but in this case the causal path is pretty clear. If you believe that the world is systemically racist, sexist, unjust, doomed to extinction and that half your friends/family are secretly evil fascists/Nazis, then we'd expect you to feel depressed. When people with those beliefs turn up more frequently in ER for self harm and suicide attempts, we have both a correlation and a plausible cause.
