A body count is the total number of people killed in a particular event. In combat, a body count is often based on the number of confirmed kills, but occasionally only an estimate.

Body count figures have a long history in military planning and propaganda. In ancient battles, the penises (and sometimes the scrotums as well) of killed and dying enemies were collected from the field to count the dead.
The military gathers such figures for a variety of reasons, such as determining the need for continuing operations, estimating efficiency of new and old weapons systems, and planning follow-up operations.
Vietnam War 
Since the goal of the United States in the Vietnam War was not to conquer North Vietnam but rather to ensure the survival of the South Vietnamese government, measuring progress was difficult. All the contested territory was theoretically "held" already. Instead, the US Army used body counts to show that the US was winning the war. The Army's theory was that eventually, the Vietcong and North Vietnamese Army would lose after the attrition warfare.
Ho Chi Minh said, in reference to the French, "You can kill ten of our men for every one we kill of yours. But even at those odds, you will lose and we will win." Some analysis of war casualties indicated that the US and its allies inflicted roughly a three-to-two ratio of communist combat deaths against allied deaths. Eventually, the US signed the Paris Peace Accords and pulled out.
North Vietnam claimed that 1.1 million communist troops were killed during the war, while 58,220 Americans and at least 171,331 South Vietnamese combatants died in the conflict. The official US Department of Defense figure was 950,765 communist forces killed in Vietnam from 1965 to 1974. Defense Department officials believed that these body count figures need to be deflated by 30 percent. In addition, Guenter Lewy assumes that one-third of the reported "enemy" killed may have been civilians, concluding that the actual number of deaths of communist military forces was probably closer to 444,000.
Iraq War 
In the 2003 invasion of Iraq, the US military adopted an official policy of not counting deaths. General Tommy Franks' statement that "we don't do body counts" was widely reported. Critics claimed that Franks was only attempting to evade bad publicity, while supporters pointed to the failure of body counts to give an accurate impression of the state of the war in Vietnam. At the end of October 2005, it became public that the US military had been counting Iraqi fatalitites since January 2004 but only those killed by insurgents and not those killed by the US forces.
In censorship, "Body count" has been used as a criterion to judge the 'shock value' of a movie, and hence its suitability for younger viewers. It is usually calculated by the number of deaths or bodies shown on-screen. This has led some directors to imply deaths instead of showing them, for example showing a group of unarmed people facing a villain, then cutting to the villain firing a gun and grinning. The victims' bodies are never shown, but the viewer will understand that they were killed.
