Adult mental health illness rates by state

Utah has the highest percentage of adults reporting mental illness of any U.S. state, according to a recent analysis from KFF.

The organization analyzed 2021-22 data from the Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health to identify the percentage of adults reporting a mental, behavioral or emotional disorder in the past year. KFF noted the estimates reflect indicators of mental illness rather than direct diagnoses. 

Nationwide, 23.1% of adults reported having a mental illness in the past year.

Here's how each state and Washington, D.C., stacked up:
