More than 1 in 8 people worldwide live with a mental disorder, yet annual experiences can be even higher at about 1 in 6 people. Behind those counts are sharp differences in disability, treatment access, and economic impact, from global DALYs and YLDs to how many people actually receive care. The pattern becomes especially striking when you compare where need shows up and where support lags.
