Surgeon General's Report on Mental Health (1999)
The first comprehensive federal appraisal of mental health in America found most people with diagnosable mental disorders received no treatment in the prior year. It documented wide gaps in care across age groups.
The report pushed mental health onto the public agenda and helped build support for parity in insurance coverage.
It set a national expectation that treatment gaps should be measured and closed.
The 2024 survey repeats the same finding at national scale for teens: most anxious adolescents do not get care. The measurement gap the 1999 report flagged is the one the new anxiety data now tracks year to year.
