A Pot of Dark Roast, the Internet, and Some Spare Time

Number of worker deaths due to homicide in multiple-fatality incidents...

Some have expressed concern that the death toll in workplace mass murder incidents is on the rise.  I offer the following for your consideration and analysis.  If anyone has the missing numbers (2007, 2000-2003) or more granular detail (1995-1999) please let me know.

2010, 17% of 401 deaths in multiple-fatality incidents = 68 due to homicide

2009, 23% of 355 fatalities = 82 homicides

2008, 14% of 495 = 69

2000-2003 multiple-fatality incidents not charted by the BLS

1995-1999, 19% of 2,949 = 575* (or ~115 per year over five years)  

*"The category includes 173 multiple-homicide incidents claiming 535 workers’ lives, plus 34 murder-suicides claiming an additional 40 workers’ lives beyond the assailants who committed suicide in these incidents.”
