Gun violence is violence committed with the use of a gun (firearm or small arm). It may or may not be considered criminal. Criminal gun violence includes homicide (except when and where ruled justifiable), assault with a deadly weapon, and suicide, or attempted suicide, depending on jurisdiction. Non-criminal gun violence may include accidental or unintentional injury or death. Included in this subject are statistics regarding military or para-military activities, as well as the actions of civilians.
According to GunPolicy.org, 75 percent of the world's 875 million guns are civilian controlled. Many guns are owned for legitimate reasons, and most are not misused. However, the 875 million guns, including the 25 percent that are government controlled, are used to kill as many as 1,000 people daily. Globally, millions are wounded through the use of guns.
Levels of gun violence vary greatly among geographical regions, countries, and even subnationally. The United States has the highest rate of gun related deaths per capita among developed countries,:29 though it also has the highest rate of gun ownership and the highest rate of officers.
According to a 2007 paper by Krause and Muggah, there is no internationally agreed upon definition of armed violence. They cite the World Health Organization definition of violence:
The intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation.
Krause and Muggah clarify that arms include bladed weapons, blunt objects, explosives, and other instruments, but that guns (in their paper, small arms and light weapons) "are disproportionately used to commit violence" worldwide. They break armed violence into five categories: inter-personal, collective, criminal, conflict, and institutional (or state).
In the United States, the term "gun crime" was common, especially in the years leading up to the passage of the Federal Assault Weapons Ban of 1994, which expired in 2004. Since then, "gun violence" is the commonly used term.
Gun Rights advocates do not use the term Gun Violence as they see this as ignoring violence that stems from non-Gun related sources. They also mention that no such term exists for other forms of "armed violence" such as "Knife Violence" or "Bludgeoning Instrument Violence." Numerous different terms have been proposed by supporters of Gun Control with the aim of "...looking for a less politically charged term for firearm regulation..."

A 1992 U.S. medical journal report shows an association between household firearm ownership and gun suicide rates, finding that individuals in a firearm owning home are close to five times more likely to commit suicide than those individuals who do not own firearms. However, a 1996 New Zealand study found no significant relationship between household guns and suicide. Assessing data from 14 developed countries where gun ownership levels were known, the Harvard Injury Control Research Center found statistically significant correlations between those levels and suicide rates. However, the parallels were lost when data from additional nations was included.:30 During the 1980s and 1990s, the rate of adolescent suicides with guns caught up with adult rates, and the 75-and-older rate rose above all others.:20-21 The use of firearms in suicides ranges from less than 10 percent in Australia to 50 percent in the United States, where it is the most common method and where suicides outnumber homicides 2-to-1.
According to U.S. criminologist Gary Kleck, studies that try to link gun ownership to victimology often fail to account for the presence of guns owned by other people. Research by economists John Lott of the U.S. and John Whitley of Australia indicates that safe-storage laws do not appear to affect juvenile accidental gun deaths or suicides. A committee of the U.S. National Research Council said ecological studies on violence and firearms ownership provide contradictory evidence. The committee wrote: "[Existing] research studies and data include a wealth of descriptive information on homicide, suicide, and firearms, but, because of the limitations of existing data and methods, do not credibly demonstrate a causal relationship between the ownership of firearms and the causes or prevention of criminal violence or suicide."
The United Nations Office on Drugs and Crime (UNODC) defines intentional homicide as "acts in which the perpetrator intended to cause death or serious injury by his or her actions." This excludes deaths: related to conflicts (war); caused by recklessness or negligence; or justifiable, such as in self-defense or by law enforcement in the line of duty. A 2009 report by the Geneva Declaration using UNODC data showed that worldwide firearms were used in an average of 60 percent of all homicides.:67 In the U.S. in 2011, 67 percent of homicide victims were killed by a firearm: 66 percent of single-victim homicides and 79 percent of multiple-victim homicides.

Some gun control advocates say that the strongest evidence linking availability of guns to death and injury is found in domestic violence studies, often referring to those by public health policy analyst Arthur Kellermann. In response to suggestions by some that homeowners would be wise to acquire firearms for protection from home invasions, Kellermann investigated in-home homicides in three cities over five years. He found that the risk of a homicide was in fact slightly higher in homes where a handgun was present. The data showed that the risk of a crime of passion or other domestic dispute ending in a fatal injury was higher when a gun was readily available (essentially loaded and unlocked) compared to when no gun was readily available. Kellerman said this increase in mortality overshadowed any protection a gun might have deterring or defending against burglaries or invasions. He also concluded that further research of domestic violence causes and prevention are needed.
Critics of Kellermann's study say that it is more directly a study of domestic violence than of gun ownership. Gary Kleck and others dispute the work. Kleck says that few of the homicides that Kellermann studied were committed with guns belonging to the victim or members of his or her household, and that it was implausible that victim household gun ownership contributed to their homicide. Instead, according to Kleck, the association that Kellermann found between gun ownership and victimization reflected that people who live in more dangerous circumstances are more likely to be murdered, but also were more likely to have acquired guns for self-protection.
Robbery and assault
|This section is outdated. (March 2014)|
The United Nations Office on Drugs and Crime defines robbery as the theft of property by force or threat of force. Assault is defined as a physical attack against the body of another person resulting in serious bodily injury. In the case of gun violence, the definitions become more specific and include only robbery and assault committed with the use of a firearm. Firearms are used in this threatening capacity four to six times more than firearms used as a means of protection in fighting crime. Hemenway's figures are disputed by other academics, who assert there are many more defensive uses of firearms than criminal uses. See John Lott's "More Guns, Less Crime".
Costs of gun violence
Violence committed with guns leads to significant public health and economic costs. Phillip J. Cook estimated that such violence costs $100 billion annually in the United States. Emergency medical care is a major contributor to the monetary costs of such violence. It was determined in a study that for every firearm death in the USA for one year from 1 June 1992, an average of three firearm-related injuries were treated in hospital emergency departments. Assault by firearm resulted in 180,000 deaths worldwide in 2013, up from 128,000 deaths worldwide in 1990. There were 47,000 unintentional firearm deaths worldwide in 2013.
Psychological costs of violence committed with guns are also clearly documented. Psychologist James Garbarino, who studies children in the U.S. and internationally, found that individuals who experience violence are prone to mental and other health problems, such as post-traumatic stress disorder and sleep deprivation. These problems increase for those who experience violence as children.

Studies that attempt to link the gun ownership of individuals to their experiences as victims (e.g., Kellermann, et al. 1993) do not effectively determine how an individual's risk of victimization is affected by gun ownership by other people, especially those not living in the gun owner's own household.

It is frequently assumed that safe-storage laws reduce accidental gun deaths and total suicides. We find no support that safe-storage laws reduce either juvenile accidental gun deaths or suicides.
