Safety.

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

Indicator2025RateChange
Burglaries of homes197.0 per 1,000−39%
Thefts from people without violence366.2 per 1,000+71%
Physical violence outside the family71.2 per 1,000−13%

Deliberate damage and vandalism315.3 per 1,000−16%
Fraud and payment card fraud518.8 per 1,000+55%

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.

A natural-disaster declaration (arrêté CatNat) lets insurers pay out for the damage. The count reflects past events, not a forecast of future risk. The list of hazards comes from each département’s major-risk file; a prevention plan in force limits building in exposed zones.
