Firearm violence injures or kills 100,000 Americans each year. This paper applies the Host-Agent-Vector-Environment model to this issue. Research on firearm violence tends to focus on two elements-the host (i.e., victims of firearm violence) and the environment (i.e., gun policies)-but little attention has been paid to the agent (the gun and ammunition) or the vector (firearm manufacturers, dealers, and the industry lobby).
Using Bureau of Alcohol, Tobacco, Firearms and Explosives data, trends in firearm manufacturing were investigated from 1990 to 2015. Outcome measures included: (1) trends in domestic gun manufacturing by weapon type; (2) trends in production by firearm caliber; and (3) 2015 market share by type of firearm and company. Data were collected and analyzed in 2016.
Overall domestic firearms production decreased slightly from 1996 through 2004, and then steadily increased from 1.7% in 2005 to 13.8% in 2013, when >10 million firearms were produced for the domestic market. The increase in total firearm production was driven by the increased production of pistols and rifles. Within the pistol category, increased production was attributable to an increase in higher caliber weapons. Similar trends were observed in gun purchases and recovered and traced crime guns.
Trends in firearm manufacturing reveal a shift toward more-lethal weapons, and this trend is also observed in gun purchases and crime gun traces. This may reflect a societal shift in cultural practices and norms related to guns and could inform strategies to reduce firearm violence.
枪支暴力每年造成 10 万名美国人受伤或死亡。本文应用宿主-代理-向量-环境模型来研究这一问题。枪支暴力的研究往往集中在两个要素——宿主(即枪支暴力的受害者)和环境(即枪支政策)——但很少关注代理(枪支和弹药)或向量(枪支制造商、经销商和行业游说团体)。
利用酒精、烟草、枪支和爆炸物管理局的数据,从 1990 年到 2015 年调查了枪支制造的趋势。结果测量包括:(1)按武器类型划分的国内枪支制造趋势;(2)枪支口径的生产趋势;以及(3)2015 年按枪支类型和公司划分的市场份额。数据于 2016 年收集和分析。
国内枪支总产量从 1996 年到 2004 年略有下降,然后从 2005 年的 1.7%稳步上升到 2013 年的 13.8%,当时为国内市场生产了超过 1000 万支枪支。枪支总产量的增加是由手枪和步枪产量的增加推动的。在手枪类别中,产量的增加归因于更高口径武器的增加。在枪支购买和追回并追查犯罪枪支方面也观察到了类似的趋势。
枪支制造趋势显示出向更致命武器的转变,这种趋势在枪支购买和犯罪枪支追查中也有体现。这可能反映了与枪支有关的社会文化习俗和规范的转变,并为减少枪支暴力的策略提供了信息。
