This report presents estimates of the prevalence of substance use in substate regions based on data from the combined 2006-2008 National Surveys on Drug Use and Health (NSDUHs).
An annual survey of the civilian, noninstitutionalized population aged 12 or older, NSDUH is sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA). It collects information from persons residing in households, noninstitutionalized group quarters (e.g., shelters, rooming houses, dormitories), and civilians living on military bases.
In 2006-2008, NSDUH collected data from 204,408 respondents aged 12 or older and was designed to obtain representative samples from all 50 States and the District of Columbia. The survey was planned and managed by SAMHSA's Office of Applied Studies (OAS), and data collection was conducted under contract with RTI International.
This report marks the fourth time that detailed estimates for substate regions (also referred to as planning regions, substate areas, or regions) in all 50 States and the District of Columbia have been presented by SAMHSA. The first report to provide such estimates used data from the 1999-2001 surveys (OAS, 2005b). The second report presented estimates for 22 measures or outcomes based on the 2002-2004 NSDUHs (OAS, 2006). The third report presented estimates for 23 measures or outcomes based on the 2004-2006 NSDUHs (OAS, 2008).
This report presents estimates for 21 measures of substance use based on the 2006-2008 NSDUHs among persons 12 or older.
Additionally, it presents estimates for underage (12 to 20) alcohol use and binge alcohol use.
These reports provide a more detailed perspective on the variations in substance use rates both within and across States than is possible with State reports (e.g., Hughes, Muhuri, Sathe, & Spagnola, 2010; Hughes, Sathe, & Spagnola, 2009).
