About as safe as the rest of Swale, which is to say ordinary. Crime runs a fraction below the district. Violence is no bigger a share here than it is nationally. The extra comes from anti-social behaviour and shoplifting. It's less a crime wave than a steady nuisance nobody has got round to fixing.
Kent Police recorded 6,179 crimes in the area in the year to May 2026, a published rate of about 103 per 1,000 residents. That's roughly 2% below the Swale average. A gap that small means Sittingbourne sits at the district's level rather than meaningfully below it. Anyone who says the town is notably worse than its surroundings hasn't looked at the figures. Anyone who says it's notably better hasn't either.
Put side by side, Sittingbourne runs at about 103 crimes per 1,000 residents and Swale as a whole at about 105. You would struggle to tell those two apart in person, and nobody walking down the high street does.
The shape of the town helps explain it. Sittingbourne is built up, averaging about 5,700 people per square kilometre across its neighbourhoods, which is town density, not village density. Unemployment is low at about 3%, and about 4% of households are overcrowded. That describes a busy working town with a compact centre where people cross paths a lot, not a place under strain. None of these figures causes crime. They just describe where it happens.
The mix of crime says more than the total. Violence and sexual offences make up about 33% of recorded crime here, against about 35% nationally. It's the biggest category almost everywhere because it includes common assault without injury, and here it runs slightly below the national share. The categories that stand out are anti-social behaviour at about 23% against 16% nationally, shoplifting at about 11% against 8%, and criminal damage and arson at about 9% against 7%. Other theft sits at about 6% against 7%, and public order at about 4% against 7%, both below the national share. Taken together, Sittingbourne has more of the visible, public-space trouble that gets reported to the council and less of the offences that make headlines. Estate agents won't mention the shoplifting. Shopkeepers will.
On what happens after a report, Kent Police charges a suspect in about 16% of cases, against about 12% nationally, over the same twelve months. That's the force's figure for the whole county, not Sittingbourne's own, and it ranks sixth of 42 forces. About 36% of cases are closed with no suspect identified. So if your bike goes, the honest expectation is that it's gone, although this force closes the case with a charge more often than most. None of this tells you how safe the area is. It tells you what happens once something has already gone wrong.
On safety Sittingbourne is middling: about as safe as the district around it, rowdier than average in public spaces, and unremarkable once you're home with the door shut.
