As others have pointed out, a lot of the murders attributed to cities can actually be narrowed down to relatively small areas or even neighborhoods. St. Louis, for example, is a great city on one side of the river but gets far more dangerous on the other side.
There is also the consideration that these figures depend on a certain accuracy of supplied data, which might not be up to nearly the same standards across the board. In some African countries, the government is the one supporting the murders, so are we actually going to get honest figures from them? It's like when people talk about X country having less rape than Y country without considering that rape is often not reported in many cultures.
