Yes, and the caveat is about the police rather than the place. Recorded crime sits below the Cornwall average. Unemployment is close to nothing. Almost nobody here lives in an overcrowded home. The thing worth thinking about in Mullion is not what happens, it is what happens afterwards.
The published rate for the area is 63 recorded crimes per 1,000 people, covering 145 recorded offences in the year to May 2026. That sits roughly 15% below the local authority average. Both figures come from the police.uk record rather than from anyone's impression of the place, and the rate uses a statistical-area population base rather than the resident headcount, so it is not something to recalculate at home.
For the comparison in full: Cornwall as a whole records about 74 crimes per 1,000 people, Mullion about 63. That is a real gap rather than a rounding artefact, though both numbers describe a county where the police have a great deal of coastline and not many people to police.
The kind of area producing those numbers is exactly what you would picture. Population density averages about 1,240 people per square kilometre across the built-up part, unemployment runs at about 2%, and roughly 3% of households are overcrowded. None of that causes anything by itself. It is simply the texture: a settled village with work, space and very few people passing through who have no reason to be there.
On the mix of offences, treat every share below as soft. With 145 recorded crimes in a year, a handful of incidents moves any category by several points, so this is a snapshot rather than a characteristic. Violence and sexual offences account for about 43% of the local total against about 35% nationally, a category that covers a wide statutory range including common assault without injury and which tops the list almost everywhere in England and Wales. Criminal damage and arson make up about 17% locally against about 7% nationally, the one genuine standout. Anti-social behaviour runs at about 12% against about 16% nationally, public order at about 10% against about 7%, and vehicle crime at about 2% against about 5%. Cars are notably safer here than they are nationally. Garden walls and bus shelters, less so.
Then there is the part nobody checks before they move. Devon and Cornwall Police charged a suspect in about 8% of cases over the same twelve months, against about 12% nationally, which ranks the force 42nd out of the 42 forces in England and Wales. About 26% of cases were closed with no suspect identified at all. That is a force-wide figure covering everything from Bude to the Isles of Scilly, not a measurement of this village, and it answers a completely different question from the crime rate. Fewer things happen here. Rather less gets resolved when they do.
Safety is one of the stronger reasons to buy here, and the numbers back the instinct rather than contradicting it. Just go in understanding that low crime and a good clear-up rate are not the same thing, and Mullion only has one of them.
