Some subjects shine; others lag. Police record less crime here than in most towns: an average of 4.7 recorded violent incidents and 5.9 recorded burglaries, vehicle thefts, thefts from vehicles and acts of criminal damage per 1,000 residents a year, 2023–2025. Mesnil-Roc'h grades B overall, better than 58% of compared French towns, and ranks #63 of 75 in Ille-et-Vilaine. What holds it back is walkability — 16% of residents live within 800 m of a bakery, and 6% of working residents walk, cycle or take public transport to work. A 70 m² home at the median €2,082/m² costs 5.6 times the median annual income per consumption unit in the Communauté de communes Bretagne Romantique. Residents’ health trails most towns (C): after allowing for care homes, deaths from 2016 to 2025 were 3% below expected, against 12% below for the median of compared French towns.

Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · For other physical violence, 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, 20.5% of the index here. That estimated share passes 10%, so treat this Safety Grade with more caution than most. The count covers the offense categories the Safety Grade uses.
