This figure counts the offences recorded on the municipality's territory, divided by the number of residents. Towns that receive commuters, shoppers and visitors every day come out higher, because offences against them are counted although they do not live there. It is therefore not a measure of the risk to a resident, which is why we do not give a safety score.
