A total institution may be defined as a place of residence and work where a large number of like-situated… — Erving Goffman

The total institutions of our society can be linked in five rough groupings. First, there are institutions established to care for persons felt to be both incapable and harmless; these are the homes for the blind, the aged, the orphaned, and the indigent. Second, there are places established to care for persons felt to be incapable of looking after themselves and a threat to the community, albeit an unintended one: TB sanitaria, mental hospitals, and leprosaria. A third type of total institution is organised to protect the community against what are felt to be intentional dangers to it, with the welfare of the persons thus sequestered not the immediate issue: jails, penitentiaries, P.O.W. camps, and concentration camps. Fourth, there are institutions purportedly established the better to pursue some work-like tasks and justifying themselves only on these instrumental grounds: army barracks, ships, boarding schools, work camps, colonial compounds, and large mansions from the point of view of those who live in the servants' quarters. Finally, there are those establishments designed as retreats from the world even while often serving also as training stations for the religious; examples are abbeys, monasteries, convents, and other cloisters.

In total institutions there is a basic split between a large managed group, conveniently called inmates, and a small supervisory staff. Inmates typically live in the institution and have restricted contact with the world outside the walls. The staff often operates on an eight-hour day and is socially integrated into the outside world.

A basic social arrangement in modern society is that the individual tends to sleep, play and work in different places with different co-participants, under different authorities, and without an over-all rational plan. The central feature of total institutions can be described as a breakdown of the barriers ordinarily separating these three spheres of life. First, all aspects of life are conducted in the same place and under the same central authority. Second, each phase of the member's daily activity is carried on in the immediate company of a large batch of others, all of whom are treated alike and required to do the same thing together. Third, all phases of the day's activities are tightly scheduled, with one activity leading at prearranged time into the next, the whole sequence of activities being imposed from above by a system of explicit formal rulings and a body of officials. Finally, the various enforced activities are brought together into a single rational plan purportedly designed to fulfil the official aims of the institution.
