Trends in workplace homicide rates are compared to the trends in U.S. homicides from 1993 to 2002, inclusively. The homogeneity of workplace homicide rates by victim demographics, circumstances, and types of events are also addressed.
Using publicly available data from several sources, Poisson models are used to statistically compare the trends of workplace homicide rates versus U.S. homicide rates and to compare trends within categories of workplace homicides.
Overall, there was a significant decline in the rates of occupational homicide of approximately 6% per year during the study time period; this decline was found to be statistically greater than the decline of all U.S. homicides (5% per year). Taxi cab drivers and chauffeurs demonstrated the greatest decline of all occupational subgroups. When looking at the circumstances of workplace homicides, only the rate of homicides committed during a robbery or other crime demonstrated a significant decline.
While workplace homicides have declined in the U.S., the declines have not occurred uniformly across demographic and occupational categories.
对1993年至2002年(含)期间美国职场杀人率的趋势与美国杀人案的趋势进行了比较。还探讨了按受害者人口统计学特征、情况和事件类型划分的职场杀人率的同质性。
利用从多个来源获取的公开数据,采用泊松模型对职场杀人率与美国杀人率的趋势进行统计学比较,并比较职场杀人案类别中的趋势。
总体而言,在研究期间,职业杀人率每年显著下降约6%;这一下降在统计学上大于美国所有杀人案的下降幅度(每年5%)。出租车司机和 chauffeurs 在所有职业亚组中下降幅度最大。在审视职场杀人案的情况时,只有抢劫或其他犯罪期间发生的杀人率呈现显著下降。
虽然美国职场杀人案有所下降,但在人口统计学和职业类别中并非均匀下降。
