GITNUXREPORT 2026

Anxiety Disorder Statistics

Anxiety disorders still touch tens of millions, with 31.1% of U.S. adults ages 18 to 29 affected in 2019 and anxiety symptoms reported by 41.7% of Americans during COVID. But the gap between need and care is the real story, since only 38.2% of U.S. adults with anxiety received any mental health service in 2019 and major work and health costs follow, making this page essential for anyone trying to understand both impact and access.

Anxiety disorders affect millions, but the most revealing pattern may be how uneven help and outcomes can be even when symptoms are common. For example, in 2020, 41.7% of U.S. adults reported anxiety symptoms at some level during COVID 19, yet only 38.2% of U.S. adults with anxiety disorders received any mental health service in 2019. We will compare prevalence, treatment gaps, and economic impact across the U.S., UK, and Australia, including how CBT and other options tend to perform in real life.
