Over the next 25 years, the projected global economic burden of depression is $12 trillion (in 2024 U.S. dollars), according to a study in Nature Medicine. This number represents 0.46% of the world’s projected annual gross domestic product (GDP).Why It’s Relevant
Major depression is a chronic, debilitating disease that creates a tremendous economic burden by reducing workforce productivity, educational attainment, and recreational activities. Previous analyses of depression’s burden, which generally focus on healthcare costs or losses in quality of life, have not fully captured the macroeconomic consequences of this disease.
By the Numbers
- Researchers collected medical and economic data from 154 countries (encompassing 96% of the world’s population) using publicly available data from the World Bank and other sources.
- They estimated that, between 2025 and 2050, the global macroeconomic burden of depression will be $12 trillion, or about $1,400 per person.
- The United States had the highest economic burden at $4.1 trillion; in terms of GDP, Lesotho had the heaviest burden at 0.77%; and Switzerland had the highest individual cost at $12,251 per person.
- When also factoring in suicide deaths related to depression, the global projected economic burden rose to $14 trillion.
The Other Side
Though the researchers considered the costs of depression-related suicide, they did not assess other contributors to mortality in people with depression, such as elevated rates of diabetes or heart disease. In addition, most of the global prevalence data on depression was derived from household surveys and not clinical assessments.
Takeaway Message
“To lessen the global economic impact of depression, we need to work together to make sure that inexpensive, evidence-based therapies are available and that supportive policies are in place,” the researchers wrote. “Increasing investment in mental health services, especially through integration into primary care, can extend access, eliminate stigma, and promote early intervention, for an estimated yearly cost of only U.S. $1–5 per capita in low-resource countries.”
