Figure. Homicide, Assault, and Case-fatality Rates, United States, 1960–2012.

Figure

The homicide rate is from the National Center for Health Statistics3 and the assault rate is from the Federal Bureau of Investigation (FBI).4 The case-fatality rate (or lethality rate) was conceptualized by Harris et al5 and is calculated herein as the homicide rate divided by the homicide rate plus the assault rate (multiplied by 100 to display percentage). An aggravated assault is defined by the FBI as an unlawful attack by one person on another for the purpose of inflicting severe or aggravated bodily injury, usually accompanied by the use of a weapon or by means likely to produce death or great bodily harm.
