Anxiety disorders have risen steadily over the past three decades, with the sharpest increases appearing among young people and in wealthier nations. The COVID-19 pandemic accelerated that trend dramatically, pushing global anxiety and depression rates up by 25% in a single year. But the climb started long before 2020, driven by a combination of economic pressure, digital culture, and broader awareness that has reshaped how many people experience and report anxiety.
The 30-Year Global Trend
Between 1990 and 2021, the global prevalence of anxiety disorders among people aged 10 to 24 rose from about 4,121 to 4,977 per 100,000 population. That’s a steady upward drift, not a sudden spike, and it played out unevenly across the world. Wealthier regions saw the largest jump: high-income countries experienced a 33.5% increase in prevalence over that period, while lower-income regions saw a smaller rise of about 21%. Central Latin America had the steepest climb of any region, while East Asia was one of the few areas where anxiety prevalence actually declined.
These numbers capture diagnosed anxiety disorders, not the broader pool of people who feel anxious but don’t meet clinical thresholds. The real scope of the increase is almost certainly larger than what diagnostic data alone can show.
The Youth Mental Health Surge
The most striking numbers belong to adolescents. In the United States, diagnosed anxiety among young people jumped 61% between 2016 and 2023, rising from 10.0% to 16.1%. Diagnosed depression rose 45% over the same window. Overall, the share of U.S. adolescents with any diagnosed mental or behavioral health condition climbed from 15.0% to 20.3%, a 35% increase in just seven years.
Emergency departments have reflected this shift. In Germany, where nationwide data tracks mental health visits closely, emergency presentations for anxiety disorders more than tripled between 2012 and 2022, rising from about 3.85 to 13.66 cases per 100,000 people. Adolescents between 15 and 19 showed particularly sharp increases, with the emergency room often serving as a first point of contact for panic attacks and acute anxiety episodes.
What the Pandemic Did
COVID-19 didn’t create the anxiety trend, but it supercharged it. The World Health Organization estimated that global prevalence of anxiety and depression increased by 25% in just the first year of the pandemic. Lockdowns, social isolation, fear of illness, grief, and economic disruption all converged at once. For many people already on the edge of clinical anxiety, the pandemic tipped the balance.
What’s notable is that rates didn’t simply snap back when restrictions eased. The adolescent data from 2023 shows continued elevation well after the acute phase of the pandemic ended, suggesting that the disruption left a lasting imprint on population-level mental health.
Economic Stress as a Driver
Financial pressure is one of the most consistent predictors of anxiety at the population level. Research on the post-pandemic inflation period illustrates this clearly. By mid-2023, nearly 79% of working-age adults in the U.S. reported that rising prices were moderately or very stressful, up from about 77% the previous fall.
The gradient by income is steep. People living below the poverty line were roughly twice as likely to report inflation-related stress compared to higher earners. Those who couldn’t afford food were seven times more likely to report that stress. People who had lost employment income, experienced long COVID, or were transgender also faced significantly higher odds. With 64% of Americans living paycheck to paycheck, even modest price increases in groceries and essentials can translate directly into chronic worry. Economists have long documented that recessions correlate with higher rates of anxiety, depression, and suicidal ideation, and sustained inflation appears to operate through similar pathways.
Social Media’s Role
Social media often gets blamed as a primary driver of rising anxiety, especially among teens. The research supports a connection, but a more modest one than headlines typically suggest. A longitudinal study tracking nearly 2,400 adolescents over three years found that more time on social media was significantly associated with increased symptoms of depressed mood, social anxiety, and physical anxiety symptoms. The effect grew stronger over time and was more pronounced for girls than boys.
However, the effect sizes were small, small enough that the researchers themselves questioned whether the relationship reaches clinical significance. Social media likely contributes to the broader anxiety landscape, particularly for vulnerable young people, but it doesn’t appear to be the dominant explanation for the population-level increases seen over the past three decades. The rise in anxiety predates smartphones and persists in populations with limited social media exposure.
Climate Anxiety Among Young People
A newer form of distress has emerged alongside traditional anxiety triggers. A global survey of 10,000 young people aged 16 to 25 across ten countries found that 59% were very or extremely worried about climate change, and 84% were at least moderately worried. More than half reported feeling sad, anxious, angry, powerless, helpless, or guilty about the climate crisis. Seventy-five percent said they believe the future is frightening.
This isn’t abstract concern. Over 45% of respondents said their feelings about climate change negatively affected their daily life and ability to function. Whether or not this qualifies as a clinical disorder, it represents a meaningful source of psychological burden for a large share of young people worldwide, one that simply didn’t exist at this scale a generation ago.
Most People With Anxiety Don’t Get Treatment
Perhaps the most sobering dimension of rising anxiety is how few people receive adequate help. A study spanning 21 countries found that among people who met diagnostic criteria for an anxiety disorder, only 27.6% received any treatment at all. Just 9.8% received treatment that could be considered adequate. In low- and middle-income countries, that figure dropped to 2.3%.
That means fewer than one in ten people with a diagnosable anxiety disorder get treatment that would actually be expected to help. Even in high-income countries, only about one in seven received adequate care. This treatment gap is wider for anxiety than for depression, partly because anxiety disorders are more often normalized or dismissed as personality traits rather than treatable conditions. As prevalence continues to climb, this gap represents a growing burden of avoidable suffering.
Why the Numbers Keep Rising
No single factor explains the sustained increase in anxiety. Several forces are working simultaneously. Greater awareness and reduced stigma mean more people seek diagnosis, which inflates reported rates without necessarily meaning more people are anxious. Better screening tools catch cases that would have been missed in earlier decades. At the same time, genuine increases in exposure to anxiety-provoking conditions, including economic instability, climate uncertainty, pandemic trauma, and constant digital connectivity, are adding real psychological load.
The pattern is clearest among young people, in wealthier countries, and among women and economically vulnerable populations. It cuts across cultures and continents, suggesting that the drivers are structural rather than local. And with the treatment gap as wide as it is, rising prevalence translates directly into rising untreated distress for millions of people worldwide.
