Anxiety symptoms by age group

The classic NCS-R age curve shows past-year prevalence of any anxiety disorder highest in young adulthood (18-29), roughly stable through middle age (30-59), and lowest in adults 60 and older. The gradient is present in every specific anxiety disorder studied, though the size of the drop-off varies: it's largest for specific phobia and social anxiety and smaller for GAD.

CDC YRBSS data have tracked a clear rise in adolescent distress over the past decade. The share of high-school students reporting persistent feelings of sadness or hopelessness rose from about 30 percent in 2013 to about 42 percent in 2021, with the largest increases among girls and among LGBTQ+ students. The Surgeon General's 2021 advisory identified youth mental health as a national priority and framed the trend as a public-health problem rather than a clinical one alone. See the reports on anxiety and college students and anxiety and school absenteeism for related pieces.

Late-life anxiety is under-recognized for at least three reasons. First, older adults are more likely to present with somatic complaints (chest pain, GI distress, fatigue) than to name anxiety directly. Second, anxiety in older adults often overlaps with medical illness and depression, complicating diagnosis. Third, most anxiety screeners were validated in younger samples. Wolitzky-Taylor and colleagues' geriatric anxiety reviews consistently argue that the low survey numbers reflect measurement gaps rather than true absence.

Cross-sectional data show today's older adults with lower anxiety rates than today's younger adults. That could mean anxiety fades with age (an age effect) or it could mean today's older adults grew up in an era with lower baseline anxiety exposure (a cohort effect). Longitudinal cohort studies suggest both contribute: individuals do show some decline in symptom levels with age on average, and generations do differ. Neither pattern fully explains the other, and both are consistent with the survey data.

Anxiety isn't spread evenly across the lifespan. In national survey data, anxiety symptoms and anxiety disorders are most common in younger adults and tend to decline with age. Kessler and colleagues' NCS-R analyses show past-year prevalence of any anxiety disorder at roughly 22-23 percent among adults 18-44, roughly 21 percent among adults 45-59, and roughly 10 percent among adults 60 and older. The CDC Household Pulse Survey, which tracks recent symptoms, shows the same age gradient, with the highest rates in younger adults.

Adolescents are a particular focus. The CDC Youth Risk Behavior Surveillance System has documented a rise over the past decade in adolescents reporting persistent feelings of sadness or hopelessness, from about 30 percent in 2013 to about 42 percent in 2021. Surveys of high-school and college students (see the report on anxiety and college students) have tracked rising anxiety-related distress. The US Surgeon General's 2021 Advisory on Protecting Youth Mental Health drew this evidence together at the national level.

Older adults present a measurement challenge. Late-life anxiety is real and often goes under-recognized, partly because older adults may report physical symptoms rather than naming anxiety, and partly because anxiety in older adults frequently occurs alongside medical illness and depression. The USPSTF's 2023 anxiety-screening recommendation is Grade B for adults 19-64 and an I (insufficient evidence) statement for adults 65 and older, reflecting the thinner evidence base in older adults rather than a lower true burden. The lower survey numbers in older age groups likely understate the true burden.

Age patterns differ between symptom surveys and diagnostic surveys. Under-recognition of anxiety in older adults likely makes their survey numbers an underestimate rather than a true low.

Cross-sectional surveys can't fully distinguish age effects (how anxiety changes with the individual's age) from cohort effects (how anxiety differs between generations who lived through different eras).
