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.
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.
