Roughly 40 million U.S. adults experience an anxiety disorder in any given year, a number that represents about 19.1% of the adult population. Over a lifetime, nearly one in three Americans (31.1%) will meet the criteria for an anxiety disorder at some point, making it the most common category of mental illness in the country.
Anxiety by the Numbers
The 19.1% annual figure captures all types of anxiety disorders combined, including generalized anxiety, social anxiety, panic disorder, and specific phobias. Social anxiety disorder alone affects an estimated 7.1% of adults in any given year, with about 12.1% experiencing it at some point in their lives. Among those with social anxiety, roughly 30% have serious impairment in their daily functioning, while another 39% experience moderate impairment.
These numbers come from large national surveys, and they reflect diagnosed or diagnosable conditions rather than everyday stress. The distinction matters: a 2022 CDC report found that about 18% of adults reported anxiety symptoms in the previous two weeks, but only a fraction of those would meet the clinical threshold for a disorder. At the severe end, 2.8% of adults reported symptoms serious enough to significantly disrupt their daily lives.
Who Is Most Affected
Women are significantly more likely to develop anxiety disorders than men. About 23.4% of women experience an anxiety disorder in any given year, compared to 14.3% of men. This gap shows up consistently across different types of anxiety and across age groups.
Age plays a notable role, too, but not in the direction most people assume. Anxiety is most common among younger and middle-aged adults. The past-year rates are similar for adults 18 to 29 (22.3%), 30 to 44 (22.7%), and 45 to 59 (20.6%). After age 60, the rate drops sharply to 9%. This doesn’t necessarily mean older adults are less anxious by nature. It may partly reflect generational differences in reporting, changes in brain chemistry with age, or the fact that many people develop coping strategies over time.
Anxiety in Children and Teens
Anxiety disorders don’t start in adulthood for most people. An estimated 31.9% of adolescents ages 13 to 18 have experienced an anxiety disorder, and the rate is fairly stable across the teen years: 31.4% among 13- to 14-year-olds, 32.1% among 15- to 16-year-olds, and 32.3% among 17- to 18-year-olds. As with adults, the gap between girls and boys is wide. About 38% of adolescent girls are affected, compared to 26.1% of boys.
Among younger children, the numbers are lower but still substantial. CDC data from 2022 to 2023 shows that 11% of children ages 3 to 17 have a current, diagnosed anxiety condition, with girls (12%) slightly more affected than boys (9%). Because young children are less likely to be screened or to articulate their symptoms, the true prevalence in this group is probably higher than what diagnosis rates capture.
Most People Never Get Treatment
Perhaps the most striking statistic about anxiety in the U.S. isn’t how many people have it, but how few get help. Only about one in four people with an anxiety disorder receive any treatment for it. That means roughly 30 million American adults with a diagnosable anxiety condition go without professional support in a given year.
This gap exists despite the fact that anxiety disorders respond well to treatment. Therapy, particularly approaches that help people gradually confront the situations they fear, has strong evidence behind it. Medication is also effective for many people. The barriers are more practical than medical: cost, lack of access to mental health providers (especially in rural areas), long wait times, stigma, and the simple fact that many people don’t recognize their symptoms as a treatable condition. Anxiety can feel like a personality trait rather than something that could change with the right support.
Anxiety Alongside Depression
Anxiety rarely travels alone. It frequently overlaps with depression, and the two conditions share enough biology and risk factors that clinicians sometimes describe them as two sides of the same coin. People with an anxiety disorder are far more likely to develop depression than the general population, and the reverse is also true. When both conditions are present at the same time, symptoms tend to be more severe, daily functioning takes a bigger hit, and treatment becomes more complex.
The 2022 CDC survey captured this overlap indirectly: among adults reporting anxiety symptoms in the previous two weeks, a substantial portion also reported depressive symptoms. This combination is especially common in younger adults and in women, the same groups that carry the highest anxiety burden overall.
Why the Numbers Keep Growing
If the headline figure of 40 million feels larger than you expected, it’s worth noting that reported anxiety rates have been climbing for years. Some of that increase reflects genuine changes in how people experience modern life: financial instability, social media use, political uncertainty, and the aftereffects of the COVID-19 pandemic have all been linked to rising anxiety levels. But some of the increase also reflects better awareness and less stigma. More people are willing to report symptoms, and more clinicians are screening for them. Both trends push the measured prevalence upward, even if the “true” rate hasn’t changed as dramatically as the numbers suggest.
What’s clear either way is the scale. Anxiety disorders affect more Americans than diabetes, asthma, or heart disease. They cost the U.S. healthcare system tens of billions of dollars annually in direct treatment and lost productivity. And with three out of four affected people receiving no treatment at all, the full toll on quality of life is almost certainly larger than any statistic can capture.
