Following are the importance of social institutions:
1. Medium of Culture : Social institutions are the medium of transfer cultural aspects like knowledge, customs, values and others from generation to generation. Hence, social institutions are important for the social life.
2. Fulfil the needs of the members: Social institutions fulfil the basic needs of human beings and also regulate their behaviour.
3. Define and regulate the behaviour of members: The social institutions prescribe and define good and bad behaviours. Schools define our way of dressing and other behaviours. The school corrects our bad behaviour by various means like punishment, reprimands and rustication. If the desiredcorrection is not achieved, then the school resorts to legal course of action. Like this, social institutions thrive to regulate the human behaviours.
4. Social Institutions provide roles to individuals: The social institutions assign role to their members based on their age and other yardsticks. Family assigns relationships based on the age. Similarly, social institutions assign role to members by defining their relationships.
