Megacity

A megacity is usually defined as a metropolitan area with a population in excess of 10 million people. Megacities can be distinguished from global cities by their rapid growth, increased in spatial population density, and also both formal and informal economics, as well as poverty, crime, and high levels of social fragmentation. In the year 2000, there were 18 megacities conurbations for example Tokyo, New York City, and Mexico City which had more than 10 millions people. The largest megacity is the Greater Tokyo Area. The population of this urban agglomeration includes areas such as Yokohama and Kawasaki. The population grew rapidly because the people can gained more benefits from a megacity just like Tokyo. There are many criteria to show that Tokyo is a megacity. For example, Tokyo has two major airports that is Tokyo International Airport and Narita International Airport. Also, the Greater Tokyo Area has an extensive railway network comprising high-speed rail, commuter rails, subways, monorails, private lines, trams and others. Now, there are around 136 individual rail lines in the Greater Tokyo Area. In Tokyo, many people can find jobs to make a living. Hence, it can be said quite a few people have problem living in Tokyo.
