This report uses data from the Treatment Episode Data Set (TEDS) to examine treatment admission data in 2014, and trend data from 2004 to 2014, nationally, regionally (by the four Census regions and the nine Census divisions), and by state or jurisdiction. The report provides information on the demographic and substance abuse characteristics of admissions to treatment aged 12 and older for abuse of alcohol and/or drugs in facilities that report to individual state administrative data systems. It is important to note that values in charts, narrative lists, and percentage distributions are calculated using actual raw numbers and rounded for presentation in this report; calculations using rounded values may produce different results. For 2014, a total of 1,614,358 admissions aged 12 and older were reported to TEDS by 49 states, the District of Columbia, and Puerto Rico (South Carolina, which is in the South Atlantic Census division, did not report sufficient admissions for 2014)
