Mental Health Statistics

You do not have to look far to see the gap between need and care, from 9.5% of US adults reporting a serious mental illness and 5.8% still facing unmet treatment needs to only 48.0% of adults with any mental illness getting counseling or therapy in the past year. Pair that reality with what is scaling now, like teletherapy reaching 23% of outpatient behavioral health visits in the US by 2021 and the global digital mental health market projected to hit $19.9 billion by 2030.

Mental health pressures are reaching millions, but the gaps in access and outcomes are where the real story lives. In the United States, 9.5% of adults reported a serious mental illness in 2022 and 5.8% still had an unmet need for treatment, while 48.0% of adults with any mental illness received counseling or therapy in the past year. Add in worldwide impact like 700,000 deaths by suicide each year and shifting use of digital tools and therapies, and you get a picture that is both sobering and uneven.
