List of countries by UNODC homicide rate per year per 100,000 inhabitants is typically expressed in units of deaths per 100,000 individuals per year; thus, a mortality rate of 30 (out of 100,000) in a population of 100,000 would mean 30 deaths per year in that entire population, or 0.03% out of the total. The reliability of underlying national murder rate data may vary. Only UNODC data is used in the main table below. In some cases it is not as up to date as other sources. See farther down as to why its data is used over other sources.
