In a developing country like India metropolitan cities act as a pole where development takes place first, get concentrated and spread to the other geographical regions. As city grows and gets mature this process of development and its internal structure also changes simultaneously. After a certain stage of development, the population of metro cities starts shifting outwards and urbanization spreads over the adjoining areas. In this situation, the population growth either is stagnant or even declines in the core areas of the urban agglomeration. Kolkata city is one such example. Kolkata became the first million city of India in 1901 and experienced fast growth until 1971; afterwards growth rate plunged down. As per the census 2011, the decadal growth rate of the Kolkata UA was just 6.87 %, well below the natural growth rate of West Bengal and India.
