Counts mix units, as SSMSI publishes them: victims for violence, offenses for burglary and damage, vehicles for vehicle theft. That’s why the page never adds them into one “total crimes”.
Offenses recorded each year. n.p.: not published (small: five or fewer in at least one of the last three years).
Chauny and the towns around it

The nearest towns of 2,500 or more, per 1,000 residents a year, 2023–2025 average.
What this data can and can’t tell you
- Where offenses happen, not where victims live. SSMSI counts each offense in the commune where police or gendarmerie recorded it happening. Towns with shops, stations, a hospital or nightlife record more per resident, and visitors are part of that count but not of the population it is divided by.
- An index, not a total. The kinds are counted in different units (victims, offenses, vehicles), so the grade adds their rates per 1,000 residents into an index and never shows a “total crimes” or a chance of being a victim.
- Hidden counts. SSMSI doesn’t publish a commune’s count when it’s small (five or fewer in at least one of the last three years). In its place it gives the average among the département’s communes whose count is hidden; the grade uses that average, never zero, and a town gets no Safety Grade when over a quarter of its index would come from such averages.
- Recorded, not all crime. Only offenses reported to or found by police and gendarmerie are counted. Reporting rates differ by kind: most vehicle thefts are reported, much family and sexual violence isn’t.
