Roughly 359 million people worldwide have an anxiety disorder, making it the most common mental health condition on the planet. That figure, from 2021 data compiled by the World Health Organization, represents about 4.4% of the global population. In the United States alone, about one in five adults experiences an anxiety disorder in any given year.
Global and U.S. Numbers
Anxiety disorders affect more people than depression, bipolar disorder, or schizophrenia. The 359 million global figure includes all types of anxiety disorders, from generalized anxiety to panic disorder to phobias. Because many people never seek a diagnosis, the true number is almost certainly higher.
In the United States, past-year prevalence sits at about 19% of adults, with notable variation by age. Adults between 18 and 44 have the highest rates, with roughly 22% affected in a given year. That drops sharply after age 60, when the rate falls to about 9%. Among adolescents aged 13 to 18, the numbers are even higher: about 32% meet criteria for an anxiety disorder, with rates consistent across the teen years.
Children are affected too. CDC data from 2022 to 2023 shows that 11% of U.S. children ages 3 to 17 have a current, diagnosed anxiety disorder.
Who Is Most Affected
Women and girls are consistently more likely to develop anxiety disorders than men and boys, across every age group and every type of anxiety. Among U.S. adults, 23.4% of women experience an anxiety disorder in a given year compared to 14.3% of men. That gap is even wider among teenagers: 38% of adolescent girls versus 26.1% of adolescent boys.
A 2022 CDC survey measuring anxiety symptoms found the same pattern. About 21.4% of women reported anxiety symptoms, compared to 14.8% of men. Severe symptoms specifically affected 3.6% of women and 2.0% of men. The reasons for this gap are complex and likely involve a combination of hormonal differences, social pressures, and differences in how men and women report symptoms.
Age plays an equally strong role. Anxiety symptoms decrease steadily as people get older. In the 2022 CDC data, 26.6% of adults aged 18 to 29 reported some level of anxiety symptoms. By age 65 and older, that dropped to 11.2%. Severe anxiety symptoms showed the same decline: 4.5% in the youngest adult group, just 1.1% among those 65 and older.
Types of Anxiety Disorders by Prevalence
Not all anxiety disorders are equally common. The most widespread type is specific phobias, with a lifetime prevalence of 12.5%. These are intense, irrational fears of particular things like heights, spiders, or flying. Social anxiety disorder is nearly as common at 12.1%, affecting people who experience overwhelming fear of social situations or being judged by others.
Generalized anxiety disorder, the type most people picture when they think of anxiety, has a lifetime prevalence of about 5.7%. It involves persistent, hard-to-control worry about everyday concerns like health, finances, or work. Panic disorder, characterized by sudden episodes of intense fear with physical symptoms like a racing heart and shortness of breath, affects about 4.7% of people over a lifetime.
Anxiety Rarely Comes Alone
One of the most striking statistics about anxiety is how often it overlaps with depression. Among people who currently have an anxiety disorder, 63% also have a current depressive disorder. Over a lifetime, that overlap climbs to 81%. This means the vast majority of people living with anxiety will also experience depression at some point, and the two conditions can reinforce each other, making both harder to manage without treatment.
The Economic Weight of Mental Illness
Anxiety disorders don’t just affect individuals. Mental illness as a whole costs the U.S. economy an estimated $282 billion per year, roughly equivalent to the economic impact of an average recession. That figure, from a 2024 Yale study, is about 30% larger than previous estimates because it accounts for effects beyond lost wages and treatment costs. People living with mental illness also tend to consume less, invest less, and gravitate toward less demanding jobs, all of which compound the economic toll.
The same study found that expanding mental health services, particularly by addressing the shortage of mental health professionals, could reduce mental illness prevalence by about 3.1% and generate societal benefits equal to 1.1% of total U.S. consumption. In practical terms, that means closing the gap between the number of people who need help and the number who can actually access it would yield returns far beyond the cost of providing care.
