Detained adults

Information on custodial sentences and execution of adult sanctions

The number of inmates is measured on a given date (reference day). This survey on custodial sentences and pre-trial detention is conducted every year on 31 January in the cantonal penal institutions of the justice and police departments. These are inventory statistics providing a snapshot at a given moment in time of the number of persons in detention.

The number of incarcerations is different from the number of inmates. This is the number of persons admitted to a custodial sentence over a twelve-month period. By extension, the number of releases is the number of person who finish their custodial sentence in a given year. These are flow statistics on the execution of sanctions, providing a longer-term view of the movements of detained persons and which, by calculating the time that has elapsed between admission and release, provides the length of imprisonment.
