It might be more appropriate to compare the most violent neighborhood in Chicago to the most violent neighborhood in a similarly-sized Venezuelan city. Just as you would compare the safest neighborhoods in both cities.
Imagine how bad Caracas is, given that the population is roughly the same (or a little larger than Chicago's). There are no official numbers for Caracas as the government "chose" not to report. But Chicago has a 15.65 murde rate vs. a +110 in Caracas (per 100 000).
I don't even want to think what's the rate for the equivalent of Engelwood in Caracas :(
So the city is in some cases MORE safe than the less urban areas, the main reason for this drop was a drop in gang violence based on the consolidation and dominant victory of a single gang. That gang is the PCC.
In areas where multiple gangs are still fighting for control the violence can be incredible.
I was giving context of what that number means. Not claiming Chicago is more violent than Caracas.
