These statistics are almost useless for determining rates of mental health issues. They measure mental health as reported by mental health professionals. Of course groups which are antagonistic or dismissive of mental health will be underrepresented. Folks who receive counseling for mental health issues at their Church will also not be represented in these numbers. That doesn't mean these other groups don't have mental health issues. It means they don't seek help for it or get help via resources that don't report these stats. All this tells me is that young liberal women are the most likely to seek help for themselves from professionals.
