Inside Sinnamary’s C− for safety
A fairly firm grade. Built on 226 offenses recorded in the graded categories over three years; with a town of 2,756, a few cases more or fewer would move it between D and C+.
Hidden counts: for sexual violence, armed robbery, 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, 9.6% of the index here. What isn’t published ↓
Per resident, against the 4,295 compared French towns with a Safety Grade.

Per 1,000 residents a year. Context only: the grade compares Sinnamary with every compared French town, not just towns its size.
Lowest rate in the graded categories first, 2023–2025 average, with the closest to Sinnamary and up to four from French Guiana.
About 21 in 1,000: recorded violent incidents a year
Each dot is one resident’s share: offenses are counted, not victims, and one person can be the victim of several.
And 9 burglaries, vehicle thefts, thefts from vehicles and acts of criminal damage, and 11 thefts without violence and frauds: 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.
