This data represents State estimates based on the combined annual National Surveys on Drug Use and Health (NSDUHs) for the current and previous measurement year. For example, the 2010 data point represents survey data from the 2009 and 2010 NSDUH surveys. Sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA), NSDUH is an ongoing survey of the civilian, non-institutionalized population of the United States aged 12 years or older. Data are typically finalized late next in the calendar year (2014 data available late 2015). More data are available at SAMHSA reports by geography.
Any mental illness (AMI) is defined as having a diagnosable mental, behavioral, or emotional disorder, other than a developmental or substance use disorder, that met the criteria found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Estimates for AMI presented may differ from previously published AMI estimates because of revised estimation procedures. For details, see the NSDUH short report titled Revised Estimates of Mental Illness from the National Survey on Drug Use and Health at http://samhsa.gov/data/.
