Statistics from Iraq Body Count.
Here are the Coalition Hostile Death Tolls for the war (all coalition countries, and only deaths due directly to enemy attack):
2003: 397 (510 annualized)
So, since 2003, there has been a pretty constant rate of hostile deaths: 738 +/- 26 per year, or a little more than 2 a day.
Now the last three months of 2006 were pretty bloody, but the first three months and July were pretty mild, so things even out.
I would suspect that if we stay in Iraq, the death tolls will be somewhat higher in 2007, but then again, I believe I have been wrong about these things before. (Which reminds me, I'll have to check out my predictions from the beginning of 2006 and see how I did).
That is all.
