After declining for over two decades, homicides in the United States rose sharply in 2015 and 2016. We dissect the homicide rise by characteristics of the victims, offenders, and incidents and devote special attention to the similarities and differences in homicide growth by race. The results indicate that the upturn was demographically and geographically pervasive and encompassed multiple event circumstances. Regardless of whether the 2014 to 2016 homicide spike was a short-run aberration in the long-term crime drop or augurs an extended increase in lethal violence, it should be explained. We offer some general directions for explanatory research on the homicide rise.

凶杀案上升的解剖

在经历了二十多年的下降之后，美国的凶杀案在2015年和2016年急剧上升。我们根据受害者，犯罪者和事件的特征来剖析凶杀案的增加，并特别关注种族杀人案增长的异同。结果表明，这种好转在人口和地理上普遍存在，并涵盖了多种事件情况。无论2014年至2016年的凶杀案激增是长期犯罪率下降中的短期畸变，还是预示着致命暴力事件的持续增加，都应予以解释。我们为解释凶杀案上升提供一些一般性指导。
