A prisoner who has not been convicted yet is referred to as what?

A prisoner who has not been convicted is referred to as a detention prisoner because this term specifically applies to individuals who are being held in custody while awaiting trial or sentencing. This status indicates that the individual is still presumed innocent and their legal process has not yet concluded.

Detention prisoners are often placed in a detention center or jail, which is different from a prison, where convicted individuals serve their sentences. In this context, the use of the term emphasizes the individual's legal situation and the notion of due process, acknowledging that they have not yet been found guilty of a crime.

The other options do not specifically capture this legal distinction. Provincial, municipal, and city prisoners typically refer to those being held in facilities operated by local governments, often after a conviction or in relation to certain types of offenses, rather than emphasizing the pre-conviction status of the individual.
