Read the following passage about large and important cities.
A ‘megacity’ is usually defined as a metropolitan area with a total population in excess of ten million people. A megacity can be a single metropolitan area or two or more metropolitan areas that converge. The terms conurbation, metropolis and metroplex are also applied to the latter. As of 2017, there are 37 megacities in existence. The largest of these are the metropolitan areas of Tokyo and Shanghai, each of these having a population of over 30 million inhabitants, with 38.8 million and 35.5 million respectively. Tokyo is the world's largest metropolitan area, while Shanghai has the world's largest city proper population. The UN predicts there will be 41 megacities by 2030.
By contrast, a ‘global city’, also called ‘world city’ or sometimes ‘alpha city’ or ‘world center’, is a city generally considered to be an important node in the global economic system. The Institute for Urban Strategies at The Mori Memorial Foundation in Tokyo issued a comprehensive study of global cities in 2016. The ranking is based on six overall categories: Economy, Research & Development, Cultural Interaction, Livability, Environment, and Accessibility. According to this particular ranking system, the top three ‘global cities’ at present are London, New York and Tokyo.
