During 1993, a total of 26,009 homicides were reported in the United States; 71% were firearm-related, and one third of all homicides occurred among persons aged 15-24 years . Since 1985, national homicide rates have increased sharply, especially firearm-related homicides and homicides among persons aged 15-24 years. However, based on data from the Supplementary Homicide Report compiled by the Federal Bureau of Investigation and reports from some cities, homicide rates have been stable or declining since 1993. To examine this trend and to assess the relative contributions of firearm- and nonfirearm-related homicide to these recent changes, CDC analyzed national vital statistics data for 1985-1994. This report summarizes this analysis, which indicates that overall rates of homicide increased from 1985 to 1991 and decreased from 1992 to 1994, and that during these two periods, rates for total firearm-related homicides and homicide among persons aged 15-24 years increased then stabilized but remained at record-high levels.
1993年，美国共报告了26,009起凶杀案；其中71%与枪支有关，所有凶杀案中有三分之一发生在15至24岁的人群中。自1985年以来，全国凶杀率急剧上升，尤其是与枪支有关的凶杀案以及15至24岁人群中的凶杀案。然而，根据联邦调查局编制的《补充凶杀报告》中的数据以及一些城市的报告，自1993年以来凶杀率一直稳定或呈下降趋势。为了研究这一趋势并评估枪支相关凶杀案和非枪支相关凶杀案对近期这些变化的相对贡献，疾病控制与预防中心分析了1985 - 1994年的全国生命统计数据。本报告总结了这一分析结果，表明凶杀案总体发生率在1985年至1991年上升，在1992年至1994年下降，并且在这两个时期，与枪支相关的凶杀案总数以及15至24岁人群中的凶杀案发生率先是上升然后趋于稳定，但仍处于创纪录的高水平。
