Between January and June 2011, the United Nations documented 1,462 civilian deaths in Afghanistan, which was a 15% increase over the same six months the year before. Anti-government forces, e.g. the Taliban, were responsible for 77% of the casualties and pro-government forces were responsible for 12%. (The remainder were indeterminate.) These and other casualty figures were compiled from published sources by the Congressional Research Service (CRS) in “Afghanistan Casualties: Military Forces and Civilians,” September 30, 2011.
Some other recently updated CRS reports include the following (all pdf).
