Safety
Crime per resident in Troarn runs lower than in 89% of compared French towns
Police and gendarmerie recorded 39 offenses in the graded categories in Troarn in 2025. Of the graded crimes in Troarn, criminal damage came up most often (2025). For 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, 14.8% of the index here. Because that share is over 10%, this Safety Grade is less sure than most.
