Almost 44 million American adults—18 percent—had some type of mental illness in the past year, according to a report by the Substance Abuse and Mental Health Services Administration (SAMHSA).

Among the states, mental illness estimates ranged from 15.83 percent in New Jersey to 22.72 percent in Oregon, HealthDay reports.

“The presence of [any mental illness] in every state reinforces that mental illness is a major public health concern in the United States,” the report noted. “Overall treatment levels remain low, and addressing the mental health of U.S. adults remains a concern for state and national public health officials.”
