I examined U.S. troop fatalities in Iraq for the period of February (when the surge escalation began) through August of 2007 for troop deaths compared to the same months of 2006. I also looked at comparing the number of U.S. troops wounded in Iraq for the period of February through July of 2007 compared to the same period in 2006 (numbers for August 2007 were not available through the data source I used --

I must add the caveat that I am not a statistician and was doing this from vague memories from my college statistics classes using the very simple statistical functions in Microsoft Excel. Those who know more about this type of analysis please feel free to let me know if I am way off base.

At least based upon my admittedly simple comparison, it appears that both the number of troop deaths since the surge escalation began and the number of troops wounded since the surge began have increased significantly when compared to the same time period in 2006. Details after the fold.

Data table for comparing troop fatalities:


The average (mean) number of troop deaths per month in 2007 was 94 (rounded) compared with 57 in 2006.

At alpha .05, the difference was significant at p<0.0014. Whether the escalation caused the average increase in troop deaths or failed to control other factors cannot be determined by this simple comparison; however, there is little doubt our troops are being killed at greater rate now than in the year before.</p>

Data table for comparing troops wounded:



Mean monthly wounded in 2007 period:  632 (rounded)
Mean monthly wounded in 2006 period:  450 (rounded)
P<0.000985 at alpha .05</p>

As we are told this week that the escalation must continue, let us remember our troops and what is happening to them the longer this absurdity continues.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
