Safety.

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

Deliberate damage and vandalism685.0 per 1,000−23%
Fraud and payment card fraud826.0 per 1,000−2%

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.
