The map below has three layers. One is for Community Statistical Areas (CSAs). The other is for neighborhoods. And the third is for 2016 homicides. The if you click on the area immediately around a homicide point, you get some information about the CSA and/or the neighborhood, depending on which layers are active. The data on CSAs and neighborhoods was provided by the Baltimore Neighborhood Neighborhood Indicators Alliance. They have a great repository of data about Baltimore.
