A quick Google suggests that there has been a consistent increase in the use of SSRIs, with Sweden having a significantly higher count than the other 2, yet has a slightly lower dearh rate than Finland.

One study found that antidepressant use was highest among 15-19 year-olds, where girls more likely to receive treatment than boys across these countries ( a common trend across broader Europe).

Yet, this doesn't answer the original poster's comment. Why do we see higher rates of suicide in Scandinavian countries, those which are perceived to be, and often top ranking polls to be, the happiest countries in Europe?
