On that grade it does better than just over half of compared French towns. Safety is another plus — an average of 2.4 recorded violent incidents and 13.4 recorded burglaries, vehicle thefts, thefts from vehicles and acts of criminal damage per 1,000 residents a year, 2023–2025. Its schools fall short: brevet results 6.2 points below the expected rate. It lags on cost of living as well: at the median price, a 70 m² home costs 7.3 times the median annual income per consumption unit in the intercommunality.

Among the graded crimes in Diémoz, the most frequent was burglary (2025). 2025 saw 44 offenses recorded locally.
Not in the gradeTheft without violence, drug use and fraud are shown for information but left out of the Safety Grade, which counts violence plus burglaries, vehicle thefts, thefts from vehicles and criminal damage per resident.
Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · When family violence, other physical violence, sexual violence and armed robbery number five or fewer in a recent year, the figure is withheld, and the index uses the département’s average instead (22.8% of the index here). As that share tops 10%, this Safety Grade carries more doubt than most. The count covers the offense categories the Safety Grade uses.
