Infrastructure is broadly categorised as
(i) Social Infrastructure It refers to the core elements of social change which serve as a foundation for the process of social development of a country. It contributes to economic processes indirectly and from outside the system of production and distribution. e.g. educational institutions, hospitals, sanitary conditions and housing facilities, etc.
(ii) Economic Infrastructure It refers to all such elements of economic change which serve as a foundation for the process of economic growth. e.g. transportation, communication, energy/power, etc.
Quality of economic infrastructure can he improved by improving social infrastructure.
Thus, these infrastructure supports each other. Hence, they both are interdependent.
