Other countries with megacities include the United States, Brazil and Pakistan, each with two.

The modern megacity may have been largely an invention of the West, but it’s increasingly to be found largely in the East. The seven largest megacities (defined as areas of continuous urban development of over 10 million people) are located in Asia, based on a roundup of the latest population data released last month by Wendell Cox’s Demographia. The largest megacity remains the Tokyo-Yokohama area, home to 37 million, followed by the Indonesian capital of Jakarta, Seoul-Incheon, Delhi, Shanghai and Manila.
With roughly 20 million inhabitants, the New York metro area, the world’s largest urban agglomeration from early in the 20th century till Tokyo surpassed it in the 1950s, ranks eighth. The only other western urban areas among the 28 biggest megacities now are Moscow (15th), Los Angeles (17th), and Paris (28th). London, which was the first modern city of a million people, is not on the list at all, with expansion long ago stopped by its green belt. In 1990, New York ranked second and Los Angeles ranked eighth.
The Caves of Steel: This is the title of a science fiction novel by the American author, Issac Asimov, who envisions an overpopulated Earth, three millennia in our future. The inhabitants of the Earth live in vast megacities that are entirely isolated from their surrounding environment and have lost the ability to leave the city’s protection and face the outdoor world. The cities are highly vulnerable and depend on their technology for the necessities of life like air, water, temperature, and food. Among other considerations, kitchen and toilet facilities are communal, and as a consequence of the overcrowded population, food is produced and distributed int heir assigned large communal kitchens where thousands are eating mass processed food at any one time of the day.
