The findings were part of a newly-released report based on surveys of 45,000 households every six months between 1992 and 1996.
Violence was defined as anything from a mere threat of violence to rape to assault to homicide.
You are comparing apples to oranges. The U.S. Department of Labor Statistics reports work-related fatalities. The questionable "survey" you reference lumps minor threats (these days "you are a jerk" can be construed as a threat) together with homicide.
Not a very scientific survey. I will stick with the U.S. Department of Labor Statitics numbers, thank you.
