The map of crime in Barcelona.

The graph shows the number of crimes committed in the territory, divided by police areas and type of crime.
The tool allows displaying it in 3D and the annual evolution since 2010.

Most of the expats are concerned about pickpockets and assault. Check the menu on the left: "delictes contra el patrimoni", and submenu "furt" (theft) and "robatori amb violència" (mugging / theft with violence-weapon-threat). You can also see the evolution since 2010.
The 3D tool is quite interesting.
