The United Nations Office on Drugs and Crime (UNODC) has conducted a study to identify the prominent factors that seem to result in high murder rates. Countries with the widest gaps between rich and poor are four times more likely to experience violent crimes than other countries. These inequitable societies are found most often in developing countries, where high poverty lacking infrastructure is commonplace. Poverty and crime go hand in hand; crime drives away businesses and investors, reducing available human capital and creating an insecure environment, which, in turn, leads to more poverty. Organized crime, like gangs and drug trafficking, also contribute to high murder rates. It is particularly true in countries like Jamaica, Honduras, and El Salvador. Organized crime is also more likely to be participated in by young males who, consequently, are also more likely to be a victim of murder. Drug and alcohol use is also related to high murder and poverty rates. Intoxication increases the risk of being involved (either as the guilty party or the victim) in a murder.
Countries that are experiencing political turmoil and violent conflict are also more likely to experience high murder rates, as is the case with El Salvador, which is still recovering from its civil war.
