Roughly 359 million people worldwide have an anxiety disorder, making it the most common mental health condition on the planet. That number, from 2021 World Health Organization data, represents about 4.4% of the global population. In the United States alone, nearly one in five adults experiences an anxiety disorder in any given year.
Global Numbers at a Glance
Anxiety disorders affect more people than depression, bipolar disorder, or schizophrenia. The 359 million figure covers all formally recognized anxiety disorders, including generalized anxiety, social anxiety, panic disorder, and specific phobias. Because many people never seek a diagnosis, especially in countries with limited mental health infrastructure, the true number is almost certainly higher.
The COVID-19 pandemic pushed these numbers sharply upward. Global cases of anxiety disorders rose by an estimated 26% in 2020 alone, with the steepest increases in countries hit hardest by the virus. Women and younger adults were disproportionately affected. Some studies conducted during the pandemic found anxiety symptoms in as many as 46% of people surveyed, though that broader figure includes people with temporary symptoms who may not meet the threshold for a clinical diagnosis.
How Common Anxiety Is in the United States
About 19.1% of U.S. adults, roughly one in five, have had an anxiety disorder within the past year. Over a lifetime, the numbers are even more striking: 31.1% of American adults will experience an anxiety disorder at some point. That means nearly one in three people in the U.S. will deal with clinical-level anxiety during their lives.
These rates have been climbing. In 2019, before the pandemic, 8.1% of U.S. adults reported symptoms of anxiety in a given survey period. That baseline jumped significantly in 2020 and the years that followed, driven by pandemic-related isolation, economic uncertainty, and disruption to daily routines.
Anxiety in Children and Teenagers
Anxiety isn’t limited to adults. CDC data from 2022 to 2023 shows that 11% of U.S. children ages 3 to 17 have a current, diagnosed anxiety disorder. Girls are slightly more likely to be affected (12%) than boys (9%). These figures only capture children who have received a formal diagnosis, so the actual prevalence among young people is likely higher. Anxiety in children often shows up differently than in adults: stomachaches, school avoidance, difficulty sleeping, and irritability can all be signs.
Who Is Most Affected
Women are significantly more likely to develop anxiety disorders than men. About one in three women will meet the criteria for an anxiety disorder during her lifetime, compared to roughly 22% of men. Across all types of anxiety, women are affected at nearly twice the rate of men, with the largest gaps appearing in generalized anxiety, panic disorder, and PTSD.
In the U.S., anxiety symptoms also vary across racial and ethnic groups, though the pattern may not be what you’d expect. Non-Hispanic white adults report the highest rates of anxiety symptoms at 16.5%, followed by non-Hispanic Black adults (14.6%) and Hispanic adults (14.5%). Non-Hispanic Asian adults report the lowest rates at 8.5%. These differences reflect a mix of factors including cultural attitudes toward reporting mental health symptoms, access to screening, and real variation in exposure to stressors. Lower reported rates don’t necessarily mean lower actual rates.
Why the Numbers Keep Rising
The increase in anxiety isn’t just a result of the pandemic. Researchers tracking global data from 1990 to 2021 have documented a steady upward trend that the pandemic accelerated rather than created. Several forces are driving the rise. Social media use, particularly among adolescents, has been linked to increased anxiety symptoms. Economic instability, climate-related stress, and greater social isolation all play a role. At the same time, reduced stigma around mental health means more people are willing to report symptoms and seek diagnosis, which inflates the numbers in a way that actually represents progress.
Young adults, particularly those ages 18 to 25, consistently show the highest rates of anxiety symptoms in U.S. surveys. This age group faces a unique combination of pressures: transitioning into independence, student debt, uncertain job markets, and heavy digital engagement.
The Treatment Gap
Despite being the world’s most common mental health condition, anxiety disorders remain undertreated in most countries. Many people with anxiety never receive a formal diagnosis or any kind of professional support. Barriers include cost, limited availability of therapists, long wait times, and the simple fact that many people normalize their symptoms for years before recognizing them as a treatable condition.
In the United States, the financial footprint of anxiety is substantial. Medical spending on anxiety and mood disorders totaled $36.8 billion as far back as 2007, with half of that going toward prescription medications. Adjusted for inflation and the post-pandemic surge in cases, current costs are considerably higher. Beyond direct healthcare spending, anxiety drives productivity losses through missed work days, reduced performance, and early disability.
Effective treatments exist, including cognitive behavioral therapy and several classes of medication, and most people who receive appropriate care see meaningful improvement. The challenge is not a lack of solutions but a gap between the number of people affected and the number who actually get help.
