Homicide

This article is about the act of killing a human being. For other uses, see Homicide (disambiguation).

Homicide (Latin: homicidium, Latin: homo human being + Latin: caedere to cut, kill) refers to the act of a human killing another human. Murder, for example, is a type of homicide. It can also describe a person who has committed such an act, though this use is rare in modern English. Homicide is not always a punishable act under the criminal law, and is different than a murder from such formal legal point of view.

Criminal homicide

Criminal homicide takes several forms and includes certain unintentional killings. The crime committed in a criminal homicide is determined by the state of mind of the defendant and statutes defining the crime. Murder, for example, is usually an intentional crime. In some jurisdictions, certain types of murders automatically qualify for capital punishment, but if the defendant in a capital case is sufficiently mentally disabled in the United States he may not be executed, for reasons described in Atkins v. Virginia, similar to those utilizing an insanity defense.

Varying by jurisdiction, a homicide that occurs during the commission of a felony may constitute murder regardless the felon's mental state with regard to the killing. This is known as the felony murder rule. Much abbreviated and incomplete, the felony murder rule says that one committing a felony may be guilty of murder if someone, including the felony victim, a bystander or a co-felon, dies as a result of his acts, regardless his intent - or lack thereof - to kill.

Criminal homicides also include voluntary and involuntary manslaughter. The mental state of the perpetrator of these crimes differs from that of one who commits murder.

Although suicide is not a form of homicide, assisting in another's suicide may constitute criminal homicide, as codified, for instance, in California Penal Code Sec. 401.

State-sanctioned homicide

Homicides may also be non-criminal when conducted with the sanction of the state. The most obvious examples are capital punishment, in which the state determines that a person should die. The killing of a human fetus during abortion is another. Homicides committed in action during war are usually not subject to criminal prosecution either. In addition, members of law enforcement entities are also allowed to commit justified homicides within certain parameters which, when met, do not usually result in prosecution; see deadly force.

Global statistics

A 2011 study by the United Nations Office on Drugs and Crime brought together a wide variety of data sources to create a worldwide picture of trends and developments. Sources included multiple agencies and field offices of the United Nations, the World Health Organization, and national and international sources from 207 countries.

The report estimated that in 2010, the total number of homicides globally was 468,000. More than a third (36%) occurred in Africa, 31% in the Americas, 27% in Asia, 5% in Europe and 1% in Oceania. Since 1995, the homicide rate has been falling in Europe, North America, and Asia, but has risen to a near "crisis point" in Central America and the Caribbean. Of all homicides worldwide, 82% of the victims were male and 18% were female; of the female victims, 40 to 70% were linked to partner- or family-related violence.

On a per-capita scaled level, "the homicide rate in Africa and the Americas (at 17 and 16 per 100,000 population, respectively) is more than double the global average (6.9 per 100,000), whereas in Asia, Europe and Oceania (between 3 and 4 per 100,000) it is roughly half." 42% of homicides globally are committed using firearms.
