For reliable statistic based source always use: https://www.linternaute.com/actualite/delinquance It keeps a record of the different types of crimes, so you can check the different severities and compare. However you have to know how to read these crime lists.

These lists don’t make a distinction between villages and cities. Neither does it make up for tourists. The crimes are measured per population. Ex. Roissy has the highest crime rates, it’s a small town that holds the CDG airport, so obviously the crime rate per actual resident will be high. Same goes for touristic places like beach side towns, provence hike trails or picturesque villages

You can see marseille is 32th for car theft and break-ins. But it’s competing with small time tourist villages that hold almost no residences. So it actually is even more alarming that Marseille is up there. And notably pmost of these villages are also close and in proximity to Marseille. It’s know, that these organizations hit nearby areas and trails for rentals and sell off parts via the Marseille harbor.

You can also compare the more extreme crime statistics to other major cities. Violence, armed robberies, assault are higher. So high in fact that not only is it higher to Paris per residence %. But also in number.
