Chapter 4
State Data: 1994-2004

TEDS aggregates data collected through the data collection systems of the Single State Agencies (SSAs) for substance abuse treatment. States have cooperated with the Federal government in the data collection process, and substantial progress has been made toward developing a standardized data set. However, because each State system is unique and each State has unique powers and mandates, significant differences exist among State data collection systems. These differences are compounded by evolving health care payment systems.

State-to-State comparisons must be made with extreme caution. Table 4.1 presents key characteristics of State data collection systems for 2004. However, these characteristics can change as State substance abuse treatment systems change, and thus may be responsible for some year-to-year variation within States. Sources of apparent variation in State-to-State substance abuse patterns include:

Table 4.5 presents, by State, the numbers of admissions aged 12 and over for 1994 to 2004. Table 4.6a is based on these numbers and presents, by State, admission rates per 100,000 population aged 12 and over for 1994 to 2004. Table 4.6b presents these rates per 100,000 population aged 12 and over adjusted for age, sex, and race/ethnicity. Age adjustment is used to take into account demographic variation across States. It compares the distributions under the assumption that each State’s TEDS population and the U.S. population had the same age, sex, and racial/ethnic composition.

Table 4.7 presents, by State and primary substance, the numbers of admissions aged 12 and over for 2004. Table 4.8a is based on these numbers and presents, by State and primary substance, admission rates per 100,000 population aged 12 and over for 2004. Table 4.8b presents these rates per 100,000 population aged 12 and over adjusted for age, sex, and race/ethnicity.

Comparisons across States should be made cautiously and should take into account the many sources of variation detailed above.
