Roughly 359 million people worldwide have an anxiety disorder, according to 2021 estimates from the World Health Organization. That’s 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, and close to one in three will deal with one at some point in their lifetime.
Those numbers have been climbing. If you searched this question because anxiety feels like it’s everywhere, the data backs up that impression.
Anxiety Rates in the United States
An estimated 19.1% of U.S. adults had an anxiety disorder in the past year, and 31.1% experience one at some point in their lives. To put that in perspective, if you’re in a room with ten people, roughly two of them are dealing with a diagnosable anxiety disorder right now, and three of them will at some point.
These figures cover the full spectrum of anxiety disorders, including generalized anxiety disorder, social anxiety, panic disorder, and specific phobias. Generalized anxiety disorder on its own affects about 2.7% of U.S. adults in a given year and 5.7% over a lifetime. It’s the type most people picture when they think of anxiety: persistent, hard-to-control worry that interferes with daily life.
Children aren’t spared. Based on CDC data from 2022 to 2023, 11% of children ages 3 to 17 have a current, diagnosed anxiety disorder. That breaks down to about 9% of boys and 12% of girls.
Who Is Most Affected
Women are consistently more likely to experience anxiety than men. For generalized anxiety disorder specifically, the past-year rate among women is 3.4%, compared to 1.9% among men. That roughly two-to-one ratio holds across most types of anxiety and appears as early as adolescence, where 3.0% of teenage girls have generalized anxiety versus 1.5% of teenage boys.
Age matters too. Adults between 18 and 44 showed some of the sharpest increases in anxiety symptoms between 2019 and 2022. The rise wasn’t limited to one demographic, though. It cut across racial groups, income levels, education levels, and geographic regions.
Anxiety Has Been Rising
The percentage of U.S. adults reporting anxiety symptoms jumped from 15.6% in 2019 to 18.2% in 2022. That increase showed up in nearly every subgroup researchers examined: men and women, across racial and ethnic groups, across income brackets, and in both urban and rural areas. The fact that the rise was so broad suggests it reflects something systemic rather than a shift in any single population.
By 2022, about one in five U.S. adults reported anxiety symptoms in the previous two weeks. Most of those cases were mild: 11.4% had mild symptoms, 3.9% moderate, and 2.8% severe. Still, the overall trend line is clearly moving in the wrong direction. Globally, new anxiety diagnoses have been increasing steadily since at least 1990, with about 600,000 new cases added in 2019 alone.
The Real-World Burden
Anxiety doesn’t just feel bad. It costs years of healthy life. Researchers use a measure called disability-adjusted life years (essentially, years lost to illness or reduced functioning) to quantify the toll of diseases. For anxiety disorders globally, that number rose 54% between 1990 and 2019, climbing from about 18.7 million to 28.7 million. That puts anxiety among the leading causes of non-fatal health burden worldwide, ahead of many conditions that get far more public attention.
This burden shows up in practical ways: difficulty concentrating at work, avoiding social situations, disrupted sleep, strained relationships. Because anxiety disorders tend to start early (often in childhood or young adulthood) and can persist for years, the cumulative impact over a lifetime is substantial.
The Gap Between Prevalence and Treatment
One of the most striking things about anxiety is how common it is relative to how often it goes untreated. Many people with anxiety disorders never receive professional help. Barriers range from not recognizing symptoms as a treatable condition, to cost, to limited access to mental health providers, to stigma that still surrounds seeking help for something that can feel like “just worrying too much.”
The numbers make one thing clear: if you’re dealing with anxiety, you’re far from alone. It is one of the most widespread mental health conditions on the planet, affecting hundreds of millions of people across every age group, income level, and country. The scale of the problem has pushed anxiety to the center of global mental health conversations in a way it wasn’t even a decade ago.
