Six figures worth understanding.

These figures come from the 2022 National Survey on Drug Use and Health, as presented by the National Institute of Mental Health. They describe mental illness and treatment among U.S. adults, not the number of people receiving coaching.

Use these figures carefully

Data can show scale. It cannot tell anyone’s whole story.

Mental illness is a broad term that includes conditions with different symptoms, severity, and support needs. National estimates are useful for understanding the bigger picture, but they cannot diagnose an individual or predict what support will be right for them.

Coaching can support future-focused goals, decisions, habits, relationships, and accountability. It does not replace treatment from a licensed mental health professional. If a person is in crisis or feels unable to cope, they should call or text 988 in the United States or contact local emergency services.

Methodology and sources

Where the numbers come from.

This page reports selected adult estimates from the National Institute of Mental Health’s mental illness statistics page. The underlying figures are based on the 2022 National Survey on Drug Use and Health, conducted by the Substance Abuse and Mental Health Services Administration. Figures are reproduced as reported and will be reviewed when a newer comparable national release is available.
