Homicide Rates - Basic International Comparisons, 2012
"The global average homicide rate stands at 6.2 per 100,000 population, but Southern Africa and Central America have rates over four times higher than that (above 24 victims per 100,000 population), making them the sub-regions with the highest homicide rates on record, followed by South America, Middle Africa and the Caribbean (between 16 and 23 homicides per 100,000 population). Meanwhile, with rates some five times lower than the global average, Eastern Asia, Southern Europe and Western Europe are the sub-regions with the lowest homicide levels.
"Almost three billion people live in an expanding group of countries with relatively low homicide rates, many of which, particularly in Europe and Oceania, have continued to experience a decrease in their homicide rates since 1990. At the opposite end of the scale, almost 750 million people live in countries with high homicide levels, meaning that almost half of all homicides occur in countries that make up just 11 per cent of the global population and that personal security is still a major concern for more than 1 in 10 people on the planet."
