Family violence rose sharply

Counted where it happens

2,750 jobs are based in Tonnerre, for 1,300 working residents. Offenses are counted in the commune where they happen, then divided by its number of residents, so a town people come into for work and shops records more per resident than one they leave. How to read it ↓

What isn’t published

3 kinds of crime aren’t published for Tonnerre

Share of the index resting on Yonne averages0.9% · limit 25%

Over 25%, no Safety Grade; over 10%, the grade says it is less certain.

SSMSI doesn’t publish a commune’s count when it’s small (five or fewer in at least one of the last three years), and publishes instead the average among the Yonne communes whose count is hidden. That average stands in for Tonnerre’s hidden cells, never a zero; here it is 0.9% of the index, so the grade rests on Tonnerre’s own figures.

How to read these numbers

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.
