Government employees experienced a rate of nonfatal workplace violence that was more than three times the rate for private-sector employees during 2011.

Alaska, Louisiana and Montana had the most gun deaths of any U.S. states in 2010, and they fall among the states with the weakest gun laws, according to the Center for American Progress.

62 percent of workplace violence involved Maryland healthcare workers in 2010, despite the fact that these workers only make up 16 percent of the state's workforce.

20,515 crimes within healthcare facilities were reported in 2012, which is a 5,524-crime increase over 2010. 

Most active shooters in the past decade acted alone, the report notes, and 51 percent were deceased following the attack. 

The U.S. outpaces other wealthy countries in violent deaths, as well as in shorter life expectancy overall.
