| Survey Response | Trends | Clients in Treatment per 100,000 Population Aged 18 and Over |
This chapter presents facility data by
State and jurisdiction for March 30, 2007. Facilities operated by Federal agencies are included in the States in which the facilities are located, although these facilities may have clients from other States.
Table 6.1 details the 2007 N-SSATS survey
response rate.
Tables 6.2a to 6.4b provide State- or jurisdictional-level detail for treatment facility and client trends presented in Chapters 2 and 3.
Tables 6.5a to 6.24b provide State- or jurisdictional-level detail for the facility tables presented in Chapter 4.
Tables 6.25a to 6.32 provide State- or jurisdictional-level detail for the client tables presented in Chapter 5.
Table 6.33 presents the number of clients in treatment per 100,000 population aged 18 and over, according to substance abuse problem treated, by State or jurisdiction.
Table 6.1. The overall response rate for the
survey was 94.5 percent. Thirty-four States or jurisdictions had response rates that equalled or surpassed the overall rate, including all of the five U.S. jurisdictions, four of which achieved response rates of 100 percent.
Tables 6.2a and 6.2b. Both the number of substance abuse treatment facilities and the number of clients in treatment were slightly higher on March 30, 2007, than on March 31, 2003.
California, New York, and Florida had the largest numbers of both facilities and clients in treatment on March 30, 2007. Together they accounted for 27 percent of all clients in treatment on that date and 25 percent of all facilities. California had 13 percent of all facilities and 12 percent of all clients. New York had 7 percent of all facilities and 10 percent of all clients, and Florida had 5 percent of all facilities and 5 percent of all clients.
The next five States with the largest number of facilities were, in descending order, Illinois, Michigan, Texas, Pennsylvania, and Washington, with a combined total of 19 percent of all facilities.
The next five States with the greatest number of clients in treatment on March 30, 2007, were, in descending order, Illinois, Pennsylvania, Washington, Michigan, and Ohio, with a combined total of 19 percent of all clients in treatment.
Clients in Treatment per 100,000 Population Aged 18 and Over
Table 6.33. For the United States, there were 458 clients in treatment per 100,000 population aged 18 and over on March 30, 2007.
The rate was highest for persons with both
alcohol and drug abuse (203 per 100,000 population aged 18 and over), followed by drug abuse only (170 per 100,000 population aged 18 and over), and alcohol abuse only (86 per 100,000 population aged 18 and over). While these rates can suggest the extent of the underlying substance abuse problem, they also reflect the level of resources available for treatment and should be interpreted with caution.
Figure 10 maps the rates of clients in treatment by State by quartile of rates—there are 12 or 13 14 States in each quartile.
