The proportion of the global population living with depression is estimated to be 322 million people—4.4% of the world’s population—according to a new report, “Depression and Other Common Mental Disorders: Global Health Estimates,” released by the World Health Organization. The report also includes data on anxiety disorders, which affect more than 260 million people—3.6% of the global population. The prevalence of these common mental disorders is increasing, particularly in low- and middle-income countries, with many people experiencing both depression and anxiety disorders simultaneously.
