Homicide rates vary across modern societies, yet most scholarly works on homicide are based on studies in developed countries, although, in less developed countries, homicide rates are higher. Homicide is multidimensional and its related social causes and prevalence differ across cultures. In low-homicide countries, most homicides occur as a result of either criminal activity or personal relationship difficulties. This paper highlights that, in one developing country - Jamaica - a different pattern is more common. High homicide rates are connected with partisan politics and neighbourhood social organization. The argument is that neighbourhood social and political factors drive high homicide rates in urban Jamaica.
