These figures count offences recorded by the police and gendarmerie in the town where they were reported. They do not measure all crime (some victims do not file a complaint) and also depend on police activity; their trend partly follows that of complaints, which have risen in recent years for domestic and sexual violence. A town that receives many visitors (shopping centre, station, tourism) has higher rates, since they are divided by its residents only. “Not released”: numbers too small, withheld by the Ministry of the Interior’s statistical service.
