Anxiety is the most common mental health condition in the United States and the world. About 19.1% of U.S. adults have an anxiety disorder in a given year, and 31.1% will meet the criteria for one at some point in their lives (NIMH). Those two figures — roughly one in five adults each year, and nearly one in three across a lifetime — are the most recent nationally representative diagnostic estimates the National Institute of Mental Health publishes. They come from the National Comorbidity Survey Replication (NCS-R), whose diagnostic interviews were collected in 2001–2003. NIMH has not fielded a newer national diagnostic survey since, so these remain the reference figures, even though the fieldwork is now more than two decades old.
Worldwide, the picture is just as prominent: an estimated 359 million people had an anxiety disorder in 2021 — about 4.4% of the global population — making it the single most common mental disorder on the planet (WHO, 2025). NIMH reports U.S. anxiety prevalence as percentages only and does not publish an official population count for any-anxiety-disorder. Applied illustratively to the more than 260 million adults living in the U.S. today, the 19.1% past-year share would translate to on the order of 50 million people — but treat that as an approximation for scale, not an official NIMH count.
This article breaks down how many people have anxiety by disorder type, sex, and age, distinguishes diagnosed disorders from a newer symptom screen, and places the U.S. numbers in a global context. For the full clinical overview, see our anxiety statistics pillar page.
Anxiety in U.S. Adults: Past-Year and Lifetime
The headline diagnostic figures for adults come directly from the NCS-R (NIMH):
- Past-year prevalence: 19.1% of adults had any anxiety disorder in the prior 12 months.
- Lifetime prevalence: 31.1% of adults will experience an anxiety disorder at some point.
A word on data vintage is essential here. These are the most recent nationally representative diagnostic-interview estimates NIMH publishes, but they were collected in 2001–2003. They should not be read as brand-new, current-year measurements. They remain widely cited precisely because no comparable national diagnostic survey has replaced them.
Anxiety by Sex and Age
Anxiety disorders are consistently more common in women than in men, and prevalence declines sharply in the oldest age group. The table below shows past-year prevalence of any anxiety disorder among U.S. adults (NCS-R, NIMH):
| Group | Past-year prevalence |
|---|---|
| Women | 23.4% |
| Men | 14.3% |
| Ages 18–29 | 22.3% |
| Ages 30–44 | 22.7% |
| Ages 45–59 | 20.6% |
| Ages 60+ | 9.0% |
The sex gap is substantial: women are affected at well over one and a half times the rate of men. Prevalence stays elevated through midlife and then drops by more than half among adults 60 and older, one of the more consistent age patterns in the anxiety literature.
Anxiety in Adolescents
Anxiety begins early. Among adolescents ages 13–18, 31.9% will experience an anxiety disorder at some point — a lifetime figure nearly identical to the adult lifetime rate, underscoring how often these conditions take hold before adulthood (NCS-A, NIMH). Of those adolescents, 8.3% have anxiety with severe impairment.
The sex difference is already pronounced in the teen years: lifetime prevalence is 38.0% among girls versus 26.1% among boys (NCS-A, NIMH). Like the adult figures, these come from the National Comorbidity Survey Replication Adolescent Supplement (NCS-A), collected in 2001–2004 — the most recent nationally representative diagnostic estimates NIMH publishes for this age group. For more on younger populations, see our teens and young adults pages.
Anxiety Disorders by Type
“Anxiety disorder” is an umbrella covering several distinct conditions. Specific phobia and social anxiety disorder are the most common, while generalized anxiety disorder and panic disorder affect a smaller but significant share of adults. The table below shows past-year and lifetime prevalence, along with the past-year split by sex (NCS-R, NIMH):
| Disorder | Past-year | Lifetime | Women (past-year) | Men (past-year) |
|---|---|---|---|---|
| Specific phobia | 9.1% | 12.5% | 12.2% | 5.8% |
| Social anxiety disorder | 7.1% | 12.1% | 8.0% | 6.1% |
| Generalized anxiety disorder (GAD) | 2.7% | 5.7% | 3.4% | 1.9% |
| Panic disorder | 2.7% | 4.7% | 3.8% | 1.6% |
Each type carries its own profile. Generalized anxiety disorder involves persistent, excessive worry across many areas of life. Social anxiety disorder centers on intense fear of social or performance situations. Panic disorder is defined by recurrent, unexpected panic attacks. Specific phobia — the most prevalent single type — involves marked fear of a particular object or situation. Across every subtype, women’s past-year rates exceed men’s, mirroring the overall sex gap.
How Severe Is Anxiety?
Not every anxiety disorder is disabling. Among adults who had any anxiety disorder in the past year, severity broke down as follows (NCS-R, NIMH):
| Severity | Share of adults with any anxiety disorder |
|---|---|
| Serious | 22.8% |
| Moderate | 33.7% |
| Mild | 43.5% |
Roughly one in five cases is classified as serious, meaning it substantially interferes with daily functioning. The remaining cases split between moderate and mild — a reminder that prevalence alone does not describe the burden a condition places on any individual.
The 2024 GAD-7 Symptom Screen: A Different Measure
A newer and much more recent data source is worth reporting carefully, because it measures something different from the diagnostic figures above. In 2024, the National Survey on Drug Use and Health (NSDUH) used the GAD-7, a brief symptom-screening questionnaire, to capture anxiety symptoms over the prior two weeks (SAMHSA, 2024):
- Adults: 7.4% (an estimated 19.4 million) reported moderate-to-severe anxiety symptoms in the past two weeks.
- Adolescents ages 12–17: 18.8% (an estimated 4.9 million) reported moderate-to-severe anxiety symptoms.
These are symptom-severity screens, not diagnoses of an anxiety disorder. A GAD-7 screen captures how someone felt over a recent two-week window; it does not apply the full diagnostic criteria used in the NCS-R. For that reason, the 7.4% adult figure is not comparable to the 19.1% past-year diagnostic prevalence and should never be presented as a lower or updated count of diagnosed anxiety. The two measures answer different questions: one estimates who currently has bothersome symptoms, the other estimates who meets the clinical threshold for a disorder.
Anxiety Worldwide and Access to Treatment
Anxiety’s prominence is global. In 2021, an estimated 359 million people worldwide had an anxiety disorder — about 4.4% of the global population — making it the most common mental disorder measured (WHO, 2025). It outranks depression in raw case counts and affects every region and age group.
Treatment, however, reaches only a minority of those affected. Globally, only about 27.6% — roughly one in four people — with an anxiety disorder receive treatment (WHO, 2025). There is no clean, anxiety-specific national treatment rate published for the United States, but the global gap illustrates how large the untreated share remains even where care exists. Anxiety frequently co-occurs with depression; for the parallel numbers, see our companion piece on how many people have depression.
Frequently Asked Questions
How many people have anxiety?
About 19.1% of U.S. adults have an anxiety disorder in a given year, and 31.1% experience one over their lifetime (NIMH) — figures drawn from diagnostic interviews collected in 2001–2003, the most recent nationally representative estimates NIMH publishes. Globally, an estimated 359 million people (about 4.4% of the population) had an anxiety disorder in 2021 (WHO, 2025).
Is anxiety more common in women or men?
Women. Among U.S. adults, past-year prevalence of any anxiety disorder is 23.4% in women versus 14.3% in men (NCS-R, NIMH). The gap holds across every disorder subtype, from specific phobia to panic disorder.
What is the most common type of anxiety disorder?
Specific phobia is the most common, with a past-year prevalence of 9.1% among adults, followed by social anxiety disorder at 7.1% (NCS-R, NIMH). Generalized anxiety disorder and panic disorder each affect about 2.7% of adults in a given year.
How many teenagers have anxiety?
Among U.S. adolescents ages 13–18, an estimated 31.9% will experience an anxiety disorder at some point, and 8.3% have anxiety with severe impairment (NCS-A, NIMH). Prevalence is higher in girls (38.0%) than boys (26.1%).
Are anxiety statistics from NIMH current?
No. NIMH’s diagnostic prevalence figures for anxiety come from the NCS-R (adults, 2001–2003) and NCS-A (adolescents, 2001–2004). They remain the most recent nationally representative diagnostic estimates available, but the underlying interviews are more than two decades old and should not be read as current-year data.
Is the 2024 figure of 7.4% the same as diagnosed anxiety?
No. The 2024 NSDUH figure — 7.4% of adults (19.4 million) reporting moderate-to-severe symptoms — is a two-week GAD-7 symptom screen, not a diagnosis (SAMHSA, 2024). It measures recent symptom severity, not whether someone meets the clinical criteria for an anxiety disorder, and is not comparable to the 19.1% diagnostic figure.
