More than one billion people worldwide are living with mental health disorders, according to new data released by the World Health Organization (WHO). The findings highlight the growing global burden of conditions such as anxiety and depression, which continue to take an immense toll on both human lives and economies.
The WHO report notes that while many countries have strengthened their mental health policies and programmes in recent years, the response remains far from sufficient. Experts warn that without greater investment and coordinated action, millions will continue to lack access to essential services.
“Mental health is a fundamental component of overall well-being, yet it remains one of the most neglected areas of public health,” WHO emphasized, calling on governments and partners to increase investment in prevention, care, and support systems. The organization stressed that protecting and promoting mental health requires comprehensive approaches, including early intervention, community-based services, and public awareness campaigns to reduce stigma.
The crisis is particularly stark in Africa, where investment and access remain critically low. Governments spend less than USD 0.50 per capita on mental health, far below the recommended USD 2, and there are only 1.4 mental health workers per 100,000 people, compared to a global average of 9. Outpatient visits are also scarce, with just 14 per 100,000 people in Africa against 1,051 globally. In Sierra Leone, nearly 99% of people with mental health conditions go untreated, while research into mental health remains extremely limited despite the growing need.
Young people across the continent are bearing much of the strain: studies show 15.3% suffer from depression, 11.8% from anxiety, 12.5% from PTSD, 9.8% from conduct disorders, and 6.6% from ADHD. Overall, around 29 million Africans, about 9% of the population, are living with depression, with striking regional variations. In northern Nigeria, clinic data suggests rates as high as 54.5%, while in South Africa, 1 in 5 women and 1 in 7 men report depressive symptoms. Among South African youth, nearly 44% face depression, 40% anxiety, and 1 in 4 report suicidal thoughts.
Between 2000 and 2015, Africa’s population grew by 49%, yet disability years lost to mental and substance use disorders increased by 52%, amounting to nearly 18 million years lost in 2015.
The WHO says urgent action is needed worldwide to ensure that mental health care is prioritized alongside physical health on national and international agendas.
