The two categories into which infrastructure can be divided are – economic infrastructure and social infrastructure.

The economic infrastructure is related to energy, transportation, and communication. It helps in economic growth. The social infrastructure is related to education, health, and housing. It enhances the quality of standard of living of people and leads to the welfare of the economy.

The economic growth attained due to perfect economic infrastructure will not be sustainable if the social infrastructure is not properly developed.

The economic and social infrastructures are complementary to each other because the economic infrastructure supports the economy from inside and the social infrastructure from outside.
