Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · For armed robbery, 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, 0.6% of the index here. The count covers the offense categories the Safety Grade uses. Crimes are counted in the commune where they happen, then divided by its residents, so a town that draws people in from around can look higher.
