Sources have stated that presently, India is home to five mega cities, with over 10 million population, but by 2030 this number will go up to seven. Delhi will continue to be the second most populous city in the world till 2030, adding a staggering 9.6 million people to its population and the most in any mega city and the facts have been revealed in the 2016 World Cities Report issued by the UN's department of economic and social affairs.
It is cited for example, and in the case of Delhi urban agglomeration, the satellite cities of Ghaziabad, Noida, Faridabad and Gurgaon are included and such inclusion makes sense as people in these contiguous areas are economically and socially integrated with the main city.
By 2030, the world's population will decisively shift to urban living with 60% of the estimated population living in cities, big or small and currently, about 54% of the world's population is urban.
Sources have added that most of the urban growth is happening in developing countries in Asia and Africa and by 2030, as many as 33 of the 41 mega cities will be from the third world. Of the 47 cities that grew by over 6% every year between 2000 and 2016, six were in Africa, 40 in Asia (including 20 in China) and just one in North America.
