Total active duty (AD) Army suicides and suicide rates vs US population suicide rates by year of suicide (2001-2011). Active duty includes Active Army and activated National Guard and US Army Reserves. Suicides are confirmed or pending confirmation (2 from 2009 and 5 from 2010) by the Armed Forces Medical Examiner System. The AD Army and US population rates are age standardized to the 2000 US Census standard population using the age groups 18 to 24, 25 to 34, and 35 to 64 years. Data sources used include the Armed Forces Medical Examiner System, the Defense Manpower Data Center, the Centers for Disease Control and Prevention Web-based Injury Statistics Query and Reporting System, and the US Census. The calculations were performed in July 2012 by the Behavioral and Social Health Outcomes Program, US Army Institute of Public Health, US Army Public Health Command, Aberdeen Proving Ground, Aberdeen, Maryland.
