Some commenters suggested that other than Haiti, violent crime and homicide in the Caribbean is not particularly high. In other words, Haiti was giving the whole place a bad reputation.
The link is to an article in a Jamaican newspaper lamenting the high homicide rate in Jamaica and in the region as a whole. The piece notes that the UN has found that the Caribbean has the highest homicide rate on Earth, at 30/100,000, surpassing Latin America proper at 26/100,000 and South and West Africa, both at 29/100,000. So the Caribbean has an even higher homicide rate than the worst parts of Africa! In 2005, Jamaica’s rate was an incredible 68/100,000.
Much of the violence seems to be related to the drug trade. Drugs are produced in South America and then trafficked to North America. The Caribbean sits between the two, and a lot of drugs are trafficked through the Caribbean.
The rape rate is also very high in the Caribbean. 4
