This report presents State estimates for 22 measures of substance use or mental health problems based on the 2003 and 2004 National Surveys on Drug Use and Health (NSDUHs).1 Sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA), NSDUH is an ongoing survey of the civilian, noninstitutionalized population of the United States aged 12 years or older. Interview data from approximately 135,500 persons were collected in 2003-2004. State estimates presented in this report have been developed using a small area estimation (SAE) procedure in which State-level NSDUH data are combined with local-area county and census block group/tract-level data from the State. This model-based methodology provides more precise estimates of substance use at the State level than those based solely on the sample, particularly for smaller States.
