Not in the gradeTheft without violence, drug use and fraud are shown for information but left out of the Safety Grade, which counts violence plus burglaries, vehicle thefts, thefts from vehicles and criminal damage per resident.
Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · Small counts of sexual violence, armed robbery, burglary, vehicle theft and theft from vehicles go unpublished (five or fewer in at least one of the last three years); the département’s average stands in, 21.8% of the index here. Because that share is over 10%, this Safety Grade is less sure than most. The count covers the offense categories the Safety Grade uses.
