Performance Improvement 2007. What Are the Local Area Prevalence Rates of Substance Use, Abuse and Dependence and Mental Health Problems in the United States?



An analysis was carried out on combined 2002, 2003, and 2004 survey data. The annual survey collects information about drug use, abuse and dependence, and mental health based on samples representative at the national, state and local levels of the civilian, non-institutionalized population of the United States aged 12 and older. This multi-year analysis estimates the prevalence of substance use, abuse and dependence, and mental health problems in 357 substate areas. These areas were defined by officials from each State and were typically based on the substance abuse treatment planning areas specified by the States in their applications for the Substance Abuse Prevention and Treatment Block Grant. This analysis includes local level estimates for 22 measures of substance use or mental health problems based on more than 200,000 respondents.

During 2002-2004, 8.1 percent of persons in the United States aged 12 or older used illicit drugs in the month before the survey. Of the 15 areas with the lowest rates of illicit drug use in the previous month, 6 were from four Midwestern States: Iowa, Kansas, Nebraska, and South Dakota. Moreover, South Dakota had three eastern regions among those with the lowest rates of illicit drug use. The highest rate (13.6 percent) of illicit drug use among persons 12 and older was reported by northern California (the 14 northernmost counties). The 15 areas with the highest rates of illicit drug in the past month were dispersed among 10 States, with Alaska accounting for 3 areas and Michigan accounting for 3 areas. Of the top 15 areas, 11 were metropolitan areas or parts of a metropolitan area. Utah County, Utah had the lowest rate of past month alcohol use (19.8 percent), and Ward 3 in the District of Columbia had the highest rate (74.7 percent). Tobacco is the second most commonly used substance in the United States after alcohol. The 15 substate areas with the lowest rates of past month tobacco use were in California and Utah, and Maryland (Montgomery County). The two highest areas were in Kentucky.
