“Homicide is caused by mix of factors at the individual, relationship, community and societal levels. Demographic structure is a well-established risk factor for homicide. Societies where young people – particularly young males – make up a greater share of the population tend to have higher homicide rates. Transitions in political regimes may also be associated with increased homicide.”

“Poverty, economic inequality, ethnic fractionalization, and the availability of guns and alcohol are also risk factors for homicide.”
