How to read these numbers.
Five figures come from the Substance Abuse and Mental Health Services Administration's 2024 National Survey on Drug Use and Health, released in July 2025. It estimates the civilian, noninstitutionalized U.S. population age 18 and older.
One figure comes from the Centers for Disease Control and Prevention's 2024 National Health Interview Survey report, published in June 2026. Medication and counseling or therapy are measured separately and may overlap.
Any mental illness includes a broad range of recognized mental health conditions. Serious mental illness is a smaller subset associated with substantial functional impairment.
