Safety.

Offences recorded in 2025, with the rate per 1,000 residents and the change from 2024.

Indicator2025RateChange
Violent thefts without a weapon00.0 per 1,000–
Armed robberies00.0 per 1,000–
Fraud and payment card fraud99.8 per 1,000–

These figures count offences recorded by the police and gendarmerie, not how safe a place feels, and not every offence is reported. Rates are per 1,000 residents (per 1,000 homes for burglaries): where many people visit but few live, as in town centres and shopping areas, they are naturally higher. Small counts are not published.
