Gun violence in the United States results in thousands of deaths and thousands more injuries annually.〔 According to the Centers for Disease Control and Prevention, in 2013, firearms (excluding BB and pellet guns) were used in 84,258 nonfatal injuries (26.65 per 100,000 U.S. citizens) 〔Nonfatal Injury Reports, 2001-2013: What caused the injury? Firearm. Centers for Disease Control and Prevention. http://webappa.cdc.gov/sasweb/ncipc/nfirates2001.html. Accessed July 25, 2015.〕 and 11,208 deaths by homicide (3.5 per 100,000),〔FastStats: Mortality - All firearm deaths. Centers for Disease Control and Prevention. http://www.cdc.gov/nchs/fastats/homicide.htm (accessed July 27, 2015).〕 21,175 by suicide with a firearm,〔http://www.cdc.gov/nchs/data/nvsr/nvsr64/nvsr64_02.pdf Page 22 (accessed July 30, 2015)〕 505 deaths due to accidental discharge of a firearm,〔 and 281 deaths due to firearms-use with "undetermined intent"〔http://www.cdc.gov/nchs/data/nvsr/nvsr64/nvsr64_02.pdf Page 23 (accessed July 30, 2015)〕 for a total of 33,169 deaths related to firearms (excluding firearm deaths due to legal intervention). 1.3% of all deaths in the country were related to firearms.〔〔There were a total of 2,596,993 deaths in the U.S. in 2013,http://www.cdc.gov/nchs/data/nvsr/nvsr64/nvsr64_02.pdf Page 4 (accessed July 30, 2015) which means that 1 out of every 78 deaths was caused by a firearm (again, excluding legal intervention). The ownership and control of guns are among the most widely debated issues in the country.〕
In 2010, according to the United Nations Office on Drugs and Crime, 67% of all homicides in the U.S. were conducted using a firearm.〔(Homicides by firearms ) UNODC. Retrieved: 28 July 2012.〕 According to the FBI, in 2012, there were 8,855 total firearm-related homicides in the US, with 6,371 of those attributed to handguns.〔(【引用サイトリンク】title=Expanded Homicide Data Table 8 )〕 61% of all gun-related deaths in the U.S. are suicides.〔 In 2010, there were 19,392 firearm-related suicides, and 11,078 firearm-related homicides in the U.S. In 2010, 358 murders were reported involving a rifle while 6,009 were reported involving a handgun; another 1,939 were reported with an unspecified type of firearm.
In 2010, gun violence cost U.S. taxpayers approximately $516 million in direct hospital costs.
Gun violence is most common in poor urban areas and frequently associated with gang violence, often involving male juveniles or young adult males. Although mass shootings have been covered extensively in the media, mass shootings account for a small fraction of gun-related deaths and the frequency of these events had steadily declined between 1994 and 2007. Between 2007 and 2013, however, the rate of active shooter incidents per year in the US increased.〔(FBI Confirms Rise in Mass Shootings in Us )〕 Handguns figured in the Virginia Tech massacre, Binghamton shootings, 2009 Fort Hood shooting, Oikos University shooting, and 2011 Tucson shooting. The Aurora theater shooting and the Columbine High School massacre were committed by assailants armed with multiple weapons.
Legislation at the federal, state, and local levels has attempted to address gun violence through a variety of methods, including restricting firearms purchases by youths and other "at-risk" populations, setting waiting periods for firearm purchases, establishing gun buyback programs, law enforcement and policing strategies, stiff sentencing of gun law violators, education programs for parents and children, and community-outreach programs. Despite widespread concern about the impacts of gun violence on public health, Congress has banned the Centers for Disease Control (CDC) from conducting research on gun violence.
The Congressional Research Service in 2009 estimated there were 310 million firearms in the U.S., not including weapons owned by the military. 114 million of these were handguns, 110 million were rifles, and 86 million were shotguns. In that same year, the Census bureau stated the population of people in the U.S. at 306 million.〔(【引用サイトリンク】title=Census Bureau Projects U.S. Population of 305.5 Million on New Year's Day )〕
== Suicides involving firearms ==
There were 19,392 firearm-related suicides in the U.S. in 2010.〔 The U.S. Department of Justice reports that approximately 60% of all adult firearm deaths are by suicide, 61% more than deaths by homicide. In the U.S., firearms remain the most common method of suicide, accounting for 51% of all suicides committed in 2006.〔(【引用サイトリンク】title=U.S.A. Suicide: 2006 Official Final Data )〕
A 1992 case-control study in the ''New England Journal of Medicine'' showed an association between household firearm ownership and suicide rates, finding that individuals living in a home where firearms are present are more likely to commit suicide than those individuals who do not own firearms, by a factor of 3 or 4. Correlation studies comparing different countries do not always find a statistically significant effect. During the 1980s and early 1990s, there was a strong upward trend in adolescent suicides with guns as well as a sharp overall increase in suicides among those age 75 and over.
