I really thought the statistics were interesting until I thought about the numbers. I am not sure about the math used in this one. Please don't see me as some smart-ass or anything.
When they calculated the totals, they seem to have found the number of deaths per month instead of per year:
(2112deaths/22months)= 96deaths/month
((96 dths/mnth)/160,000)x100,000 = 60deaths/100,000/month in Iraq.
What they should have done was:
The 2112 deaths over 22 months translates into 1152/year. (2112/1.83yr).
The number of these deaths/year per 100,000 would be 720. ((1152/160,000)x100,000).
That's just what I happened to notice. Washington DC doesn't have a murder rate of 80/100,000/month (not even back in the early 90s). That is more of a yearly rate.
Let me know if I am wrong. I could have messed up some figures myself.
