Deaths while on active duty in the U.S. Armed Forces, 1990-2011.

Crude mortality rates are lower among U.S. military members than their civilian counterparts; service members must be healthy when they enter service and deaths from illnesses are relatively infrequent. From 1990 through 2011, there were 29,213 deaths of U.S. military members while on active duty (crude overall mortality rate: 71.5 per 100,000 person-years). The most deaths occurred in years when major combat operations were ongoing; from 2004 to 2007, war-related injuries accounted for approximately 40 percent of all deaths. From 2000 to 2011, two-thirds of all deaths unrelated to war were caused by transportation accidents (n=4,761; 37%), other accidents (n=1,358; 10%) and suicides (n=2,634; 20%). From 2005 to 2011, the proportion of deaths due to suicide increased sharply while the proportion due to transportation accidents generally decreased; as a result in 2010 and 2011, suicides accounted for more deaths of service members than transportation accidents. The current focuses of the Services on safety and mental health are clearly indicated to minimize the premature loss of lives of young men and women in military service.
