Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · For other physical violence, sexual violence, burglary, vehicle theft and theft from vehicles, this figure isn’t published when it’s small (five or fewer in at least one of the last three years); the index uses the département’s average instead, 23.2% 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.
