Publicly available firearm data are difficult to access. Trauma registry data are excellent at documenting patterns of firearm-related injury. Law enforcement data excel at capturing national violence trends to include both circumstances and firearm involvement. The goal of this study was to use publicly available law enforcement data from all 50 states to better define patterns of firearm-related homicides in the young.
All homicides in individuals 25 years or younger in the United States over a 37-year period ending in 2016 were analyzed: infant, 1 year or younger; child, 1 to 9 years old; adolescent, 10 to 19 years old; and young adult, 20 to 25 years old. Primary data files were obtained from the Federal Bureau of Investigation and comprised the database. Data analyzed included homicide type, situation, circumstance, month, firearm type, and demographics. Rates of all homicides and firearm-related homicides per 1 million population and the proportion of firearm-related homicides (out of all homicides) were stratified by year and compared over time using simple linear regression.
A total of 171,113 incidents of firearm-related homicide were analyzed (69% of 246,437 total homicides): 5,313 infants, 2,332 children, 59,777 adolescents, and 103,691 young adults. Most (88%) were male and Black (59%) with a median age of 20 years. Firearm-related homicides peaked during the summer months of June, July, and August (median, 1,156 per year; p = 0.0032). Rates of all homicides (89 to 53 per 1 million population) and firearm-related homicides (56 to 41 per 1 million population) decreased significantly from 1980 to 2016 (β = -1.12, p < 0.0001 and β = -0.57, p = 0.0039, respectively). However, linear regression analysis identified a significant increase in the proportion of firearm-related homicides (out of all homicides) from 63% in 1980 to 76% in 2016 (β = 0.33, p < 0.0001).
For those 25 years or younger, the proportion of firearm-related homicides has steadily and significantly increased over the past 37 years, with 3 of 4 homicides firearm related in the modern era. Despite focused efforts, reductions in the rate of firearm-related homicides still lag behind those for all other methods of homicide by nearly 50%. That is, while the young are less likely to die from homicide, for those unfortunate victims, it is more likely to be due to a firearm. This increasing role of firearms in youth homicides underscores the desperate need to better direct prevention efforts and firearm policy if we hope to further reduce firearm-related deaths in the young.

公开可得的枪支数据难以获取。创伤登记数据在记录与枪支相关的伤害模式方面表现出色。执法数据擅长捕捉包括情况和枪支参与在内的全国暴力趋势。本研究的目的是利用来自全美 50 个州的公开执法数据,更好地定义年轻人中与枪支相关的凶杀模式。
对美国在 1980 年至 2016 年期间的 37 年间,年龄在 25 岁及以下的所有枪支相关凶杀案(婴儿,1 岁或以下;儿童,1 至 9 岁;青少年,10 至 19 岁;和青年成年人,20 至 25 岁)进行分析。从联邦调查局获得主要数据文件,并将其作为数据库。分析的数据包括凶杀类型、情况、环境、月份、枪支类型和人口统计数据。每百万人口中所有凶杀案和与枪支相关的凶杀案的发生率以及与所有凶杀案相比枪支相关凶杀案的比例(占所有凶杀案的比例)按年份分层,并使用简单线性回归进行比较。
共分析了 171,113 起与枪支相关的凶杀案(246,437 起总凶杀案中的 69%):5313 名婴儿、2332 名儿童、59777 名青少年和 103691 名青年成年人。大多数(88%)是男性和黑人(59%),中位数年龄为 20 岁。与枪支相关的凶杀案在 6 月、7 月和 8 月的夏季月份达到高峰(中位数每年 1156 起;p = 0.0032)。从 1980 年到 2016 年,所有凶杀案(89 至 53 每百万人口)和与枪支相关的凶杀案(56 至 41 每百万人口)的发生率显著下降(β=-1.12,p<0.0001 和β=-0.57,p=0.0039,分别)。然而,线性回归分析发现,与枪支相关的凶杀案(占所有凶杀案的比例)从 1980 年的 63%增加到 2016 年的 76%(β=0.33,p<0.0001)。
对于 25 岁及以下的人来说,过去 37 年来,与枪支相关的凶杀案的比例稳步显著上升,在现代社会中,4 起凶杀案中有 3 起与枪支有关。尽管做出了集中努力,但与枪支相关的凶杀案发生率的下降仍落后于其他所有凶杀案方法近 50%。也就是说,尽管年轻人死于凶杀的可能性较小,但对于那些不幸的受害者来说,更有可能是因为枪支。这种枪支在年轻人凶杀案中越来越重要的作用突显了,如果我们希望进一步减少年轻人中的枪支死亡人数,迫切需要更好地指导预防工作和枪支政策。
