Regional Crime Comparision
InSight Crime has an article that compares crime in Nicaragua to other countries in the region. The punchline is that besides being lower, most of it isn't even where you are likely to be -- unless you are running drugs.
While Managua is, as you would expect, Nicaragua's most violent city, it is not the most dangerous area based on per capita homicide rates.
According to Granera, the most violent region is the remote Autonomous Region of the Southern Atlantic, or RAAS (see picture), with a rate of 42.7 homicides per 100,000 people in 2011, comparable to Nicaragua's national rate of 12 murders per 100,000 inhabitants. Neighboring Guatemala has a rate of 43 homicides per 100,000.
The police chief said several other departments have murder rates on par with those seen in Europe, including Carazo, Leon, and Madriz, which saw rates of 2.2, 4.3, and 3.3, respectively.
