Of the World's top Urban Sprawls....


The national capital, which was not even among the world’s top ten urban sprawls by population in 1990, is already the second largest behind Tokyo and will continue to retain that position till 2025, according to a UN projection.
Mumbai, which was at No.5 in 1990, has climbed to the fourth spot and will be No.3 in the next 13 years.
The projections, made in the UN’s recent publication, State of The World’s Cities 2012-13, suggest that the Delhi urban agglomeration will have a population of 28.6 million by 2025, still well behind Tokyo’s 37.1 million. Mumbai will, in the meantime, have reached a population of 25.8 million.
The fastest growing of the world’s mega cities over the next 13 years will be Dhaka, which was ranked No. 23 in 1990 but was already at No. 9 in 2010, and is projected to be the fifth largest urban area in the world by 2025. Another city in India’s neighbourhood, Karachi, has also been rapidly climbing up the rankings, from No. 21 in 1990 to No. 10 in 2010 and No. 9 in 2025.
Kolkata, which was ranked No. 7 in 1990, has been more or less holding on to its position, having dropped just one rank till 2010, and is projected to hold on to that position in 2025.
New York and Mexico City, which were the two biggest urban agglomerations two decades ago, are projected to drop to the bottom half of the top 10 list in a little more than a decade from now.
Delhi and Mumbai are both projected to see populations increasing by 29% over the same period, but even this is a significant drop from the rates at which they have grown since 1990.
