Man is a social creature. Being in society he has some wants and assigned aims, to comply them he is interdependent and collectively attempts to these needs and objectives. This they perform on the basis of institution, being organised on the basis of pre-established traditions and customs. Hence, it can be said that institution is that which people adopts to mean for fulfillment of own needs and objectives with procedures and behaviour.
To this E.S. Bogardus said," A social institution is a structure of society that is organized to meet the needs of people through well established procedures."
