Avg. daily Coalition fatality rate for the last month: 3.52
(nearly all Americans, and excluding Iraqis)
Last year, October 2005: 3.19.
Overall daily average to date is 2.31. Total US dead as of today: 2826.
Iraqi monthly military/police fatalities: 224.
Last year, October 2005: 215.
Total Iraqi military dead: 5703.
Note that I've seen media reports suggesting the Iraqi military casualty figures are signficant undercounts.
Iraqi monthly civilian fatalities: 1,315
Last year, September 2005: 463.
To-date total since March 2005: 18,962. Note that the civilian numbers are far less accurate than others (most likely to be greatly underestimated, or even ridiculously underestimated), but could still be useful in determining trends.
Comments: there's a deteriorating trend, but it's too early to determine if American casualty rates are entering a permanently higher level. Civilian casualties remain terrible.
