In 2008, there were 418,000 homicides around the world, with far too many countries recording a murder rate of more than 10 per 100,000, which the World Health Organization regards as an epidemic. A single homicide in America costs the individual and society $9.1 million.
2008年全球发生凶杀案共计418,000起，太多国家有记录的谋杀率达到100，000分之10以上。世卫组织将其视为一种传染病。美国一起凶杀案给个人和社会造成的损失高达910万美元。如果按照全球国民收入计算，仅此一项暴力犯罪就让全球GDP付出1.7%的代价。
