A prison cell (also known as a jail cell) is a small room in a prison or police station where a prisoner is held. Cells greatly vary by their furnishings, hygienic services, and cleanliness, both across countries and based on the level of punishment to which the person being held has been sentenced. Cells can be occupied by one or multiple people depending on factors that include, but are not limited to, inmate population, facility size, resources, or inmate behavior.
