The seeds are planted early, and they grow.
Depression and anxiety affect over 1 billion people globally, with women comprising 581.5M cases versus 513.9M men affected. Mental disorders cost €850 billion annually in lost productivity and reduce life expectancy by 9-13 years depending on condition.

WHO reports over 1 billion people worldwide experience mental health problems, with depression and anxiety most common. The figure has grown faster than global population since 2011, disproportionately affecting women and low-income populations.
The World Health Organization released a stark accounting this week: more than one billion people across the globe are living with a mental health disorder. That number has grown faster than the world's population itself over the past decade, a gap that widens each year and shows no sign of closing.
Depression and anxiety dominate the landscape. They are the two most prevalent conditions, appearing in every country and every economic stratum, though they strike hardest at people with low and moderate incomes. The gender divide is pronounced: 581.5 million women carry these diagnoses compared to 513.9 million men. The COVID-19 pandemic sharpened this disparity, pulling more women into mental illness even as it strained systems everywhere.
The young are not spared. Seven percent of children between five and nine years old experience a mental disorder. Among adolescents aged ten to nineteen, the figure climbs to fourteen percent. What troubles researchers most is the trajectory: roughly one-third of all adult mental illness takes root before age fourteen. Half of it emerges by eighteen. Nearly two-thirds by twenty-five. The seeds are planted early, and they grow.
Suicide casts the darkest shadow. In 2021 alone, approximately 727,000 people ended their lives. The WHO's director of noncommunicable diseases and mental health, Dévora Kestel, called it a tragedy that persists with unacceptable frequency. Among young people, suicide ranks as a leading cause of death across all countries and income levels—a distinction that cuts across every boundary of geography and wealth. Yet the world is not on track to meet its own targets. The Sustainable Development Goal calls for a one-third reduction in suicide rates by 2030. At the current pace, the world will achieve only a twelve percent reduction. The gap between aspiration and trajectory is widening.
The economic toll is staggering. Depression and anxiety alone drain 850 billion euros annually from global productivity—money that vanishes from wages not earned, work not completed, potential not realized. Mental illness also shortens life itself. People with schizophrenia die nine years earlier on average. Those with bipolar disorder die thirteen years earlier. The disorder does not merely diminish the present; it steals the future.
Yet even the figure of one billion may be an undercount. Stigma remains a powerful silencer. People do not seek help. Doctors do not diagnose. Cases go unnamed and uncounted. The true scale of the crisis may be larger still, hidden behind shame and silence, waiting for a world willing to see it clearly.

La Conversación del Hearth Otra perspectiva de la historia
Why does the WHO think the actual number might be higher than one billion?
Because stigma keeps people from seeking help or admitting they're struggling. If you're ashamed, you don't go to a doctor. If you don't go to a doctor, you don't get counted. The statistics are only as good as the people willing to be honest about what they're experiencing.
The report mentions the pandemic made things worse for women specifically. What happened there?
COVID isolated people, disrupted routines, created economic uncertainty. Women often carry more of the caregiving burden—children at home, elderly parents—so the pressure intensified. The pandemic didn't create the inequality; it exposed and deepened it.
A thirteen-year reduction in life expectancy for bipolar disorder seems almost unimaginable. Is that from the condition itself or from how people live with it?
Both. The condition affects the body—cardiovascular stress, metabolic changes. But it's also how the world treats people with it. Poverty, lack of access to care, the weight of being stigmatized—these shorten lives too.
The suicide numbers are sobering. But you said the world won't meet its 2030 targets. What would it take to actually get there?
A fundamental shift in how societies fund and prioritize mental health. Right now it's underfunded everywhere. You'd need more therapists, more hospitals, more prevention programs in schools. You'd need to destigmatize asking for help. And you'd need to do it fast, because the current path leads nowhere.
Why does mental illness show up so early in children's lives?
We don't fully know. Genetics play a role. So does environment—trauma, poverty, instability. But the fact that two-thirds of adult mental illness begins by age twenty-five tells us something: if you want to prevent it, you have to start young. Prevention is cheaper and more humane than treating crisis.
