Mental illness is a major public health concern. One in six Idahoans has been diagnosed with a mental health disorder.
The National Survey on Drug Use and Health conducted by the Substance Abuse and Mental Health Services Administration estimates 4.7 percent of Idahoans over age 17 – more than 53,000 – have a serious mental illness, a disorder that causes substantial functional impairment and urgently requires treatment.
The national average is 4 percent. Idaho ranks 10th in the highest share of adults with a serious mental illness based on annual averages from the 2011 and 2012 national surveys. New Jersey had the lowest rate of serious mental illness at 3.1 percent, and West Virginia was highest at 5.5 percent.
