That is assuming that facebook usage is globally homogenous.

Social climates, sex and age play a huge factor. Young insecure girls that are bombarded with how they should look, and what their friends are doing without them will not be affected as the boomer who only goes onto facebook marketplace to sell, talk with family, or the kind that posts trump memes. Heres some interesting data. https://www.smartinsights.com/social-media-marketing/social-...

I don't think usage of instagram is much different here in western europe and the results regarding teen suicide are not the same seemingly. So I'm not sure of what to think.

Open to being proven wrong about instagram usage in the us vs europe. I haven't really looked into it. But it seems all teens and preteens here are hooked on it.

It is multidimensional, it does not mean that social media is going to have the same effect even among the same country with the same usage. Widespread anti-semitism for instance in the US did not cause the holocaust as it did in Germany. The culture in parts different parts of western Europe is different than it is from southern US and northern US.

You will find no shortage of people quitting social media and reporting benefits around the world, the algorithms on instagram will also vary with what is shown. Without enough data I cannot quantify it but other factor such as wealth are also associated with suicides, low income and high income communities have lower suicide rates. https://en.wikipedia.org/wiki/List_of_countries_by_suicide_r...
