Global Depression Statistics

Depression affects about 300 million people worldwide and is tied to 1.0 million suicide deaths globally, but the page also highlights the gap between health need and real access, including how many people still go untreated even in high resource settings. You will see what this looks like across countries, from major work and healthcare losses to the rising role of telehealth, alongside costs that reach into the hundreds of billions.

Depression touches an estimated 300 million people worldwide, yet the gap between need and care is still wide and costly. In 2019, depressive disorders contributed to about 3.1% of global total DALYs and were linked to 1.0 million suicide deaths, while many countries report that large shares of adults do not receive treatment. Here, we connect the human toll to the economic and health impacts across regions, from lost workdays to higher risks of chronic disease.
