However in Nicaragua things are not as the world would likely expect or imagine them to be.
One quick measure of any populace's happiness is suicide rates. Surely such an impoverished and war-weary people might be inclined to pull the plug, throw in the towel. Suicide rates according to the World Heath Organization in Nicaragua are 6.9 per 100,000. However, wealthy southern neighbor Costa Rica's rate is higher, at 11.8 per 100,000. Both pale in comparison with the really wealthy countries like the USA at 21.7, Australia at 26.3 or France at 35.5, not to mention Switzerland at 36.5 or Japan at 50.6 per 100,000.
So money does not necessarily buy happiness, but it should keep crime down. Crime statistics are a shaky business, the more efficiently a country reports their crimes the further they slide down in the safety rankings, but it does prove useful as a reference point. According to Interpol in 2001, crime rate per 100,000 was 9,927 for England, 7,736 for Germany, 4,161 for the USA and 1,750 for Nicaragua. Could Nicaragua be home to less than half the crime in England or Germany?
Murder rates are a popular measure for a country's level of violent crime and are more reliable than most, as murders rarely go unreported. The world's homicide rate is currently estimated at 8.86 per 100,000. Latin America is quite a bit rougher, with an average of 22.9 murders per 100,000 in the region. Most neighbor countries of Nicaragua in Central America are on the upper end of the world's scale, exactly where the world might expect Nicaragua would be located. Countries like El Salvador at 117 per 100,000, Guatemala at 45 per 100,000 and Honduras at 41 per 100,000. In North America, the US murder rate is 7.1 per 100,000, yet its famously violent cities weigh in at 14.8 per 100,000 for Los Angeles, 21.9 for Chicago, 31.7 for Atlanta, with Washington, D.C. at 41.8 and New Orleans at 43.3.
Little Costa Rica, the "oasis of peace", is at 7.2, the same as the US and significantly safer than most other Central American republics. What about Nicaragua? Nicaragua suffers only 3.4 per 100,000, making it the least violent country in Central America and one of the safest in all the hemisphere. Nicaragua safer than Costa Rica? How is that possible? Could it be that Nicaragua is safe because it is actually a police state that has come down hard on the population, locked everyone up? Incarceration rates suggest otherwise. The USA leads the world in prison inmates with a staggering 682 per 100,000 in jail. Canada has 123 per 100,000, Scotland 119 and Germany 96, while Nicaragua has only 57 per 100,000 imprisoned. How about on a regional level: comparing Nicaragua vs. Central America in total inmates? Honduras has 9,816 inmates under key, El Salvador 9,378, Guatemala 7,834, Costa Rica 5,542 and Nicaragua at 3,913. How does one explain that Costa Rica has a higher murder rate and more people in prison than bad-boy Nicaragua? Especially considering that Costa Rica is home to 1.2 million less people than Nicaragua? Perhaps it is Nicaragua's police? Do they have menacing, heavily armed forces that guard the country with intimidating 24 hour patrols? Police officers per thousand statistics rate Italy at 5.3 police per thousand, Spain at 4.7, Germany at 4.4, El Salvador at 2.6, Costa Rica with 2.5 and Nicaragua with 1.2 police per thousand. Nicaragua has less than half the police density of Costa Rica. What those numbers don't show is that Nicaragua's small police force is also largely unarmed. In fact more than half of Nicaraguan police do not carry firearms at all.
