Trends

Tables 6.2a-b. California and New York had the largest numbers of both facilities and clients in treatment in every year from 2007 through 2011. On March 31, 2011, California had 12 percent of all facilities and 11 percent of all clients. New York had 7 percent of all facilities and 10 percent of all clients.

Florida and Illinois ranked 3rd or 4th in the total number of facilities from 2007 through 2011. Florida was 3rd or 4th for number of clients, but the number of clients in Illinois has been decreasing in recent years.

A core group of States (Michigan, Colorado, Pennsylvania, and Washington) generally ranked 5th to 10th in both the numbers of facilities and of clients from 2007 to 2011. Texas and North Carolina are part of this group based on the number of facilities, and Maryland and Massachusetts are part of it based on the number of clients.

Table 6.33 and Figure 8. For the United States, there were 473 clients in treatment per 100,000 population aged 18 and over on March 31, 2011. The rate was highest for persons with both alcohol and drug abuse (203 per 100,000 population), followed by drug abuse only (183 per 100,000 population), and alcohol abuse only (87 per 100,000 population). Figure 8 maps the rates of clients in treatment by State by quartile of rates­—there are 12 or 13 States in each quartile.
