It's not just that we don't have a lot of data, it's that the only area about youth mental health that we actually do have a lot o data about is the suicide rate, which is decreasing. It's increasing in America, but it's increasing for everybody, not just young people. There's no clear youth-specific decline in mental health except a vague increase in teens that report feeling that their mental health is poor, but this is plagued by bias. I don't think the problem is that we don't have enough data to say if the youth mental health crisis is real, it's that I think we have enough to say that it isn't.
