The other side of the ledger: more than half of people with depression worldwide get no treatment
A World Health Organization review of 37 studies put the median share of people with major depression who receive no treatment at 56%. Any account of oversold conditions has to hold that number too.
Caveat on this rating: Treatment gap figures depend on survey instruments that define who counts as a case, and critics argue those instruments over-count distress as disorder, especially across cultures. The 2004 data are old and coverage has changed. The row uses the figure for what it measures, people meeting survey criteria who received no care, and does not claim all of them need medication.
