  6. MEGA CITY X A megacity is a very large city, typically with a population in excess of 10 million eople (1 cr). x Precise definitions vary: the United Nations Department of Economic and Social Affairs in its 2014 "World Urbanization Prospects" report counted urban ag9lomerations having over 10 million inhabitants. A University of Bon report held that they are "usually defined as metropolitan areas with a total population of 10 million or more eople". Others list cities satisfying criteria of either 5 or 8 million and also have a population density of 2,000 per square kilometer. A megacity can be a single metropolitan area or two or more metropolitan areas that converge X The terms conurbation, metropolis, and metroplex are also 1ed to the latter xThe term metacityhas been used to describe metropolitan conurbations containing over 20 million people.

  9. GLOBAL CITIES A global city,also called world city or sometimes alpha city or world center, is a city which is a primary node in the global economic network. "X The most complex node is the "global city", with links binding it to other cities having a direct and tangible effect on global socio-economic affairs. The concept comes from geography and urban studies, and the idea that globalization is created, facilitated, and enacted in strategic geographic locales according to a hierarchy of importance to the operation of the global system of finance and trade. The term "global city", rather than"megacity", was popularized by sociologist Saskia Sassen in her 1991 work, The Global City: New York, London, Tokyo. World city", meaning a city heavily involved in global trade. appeared in the May 1886; Patrick Geddes later used the term "world city" in 1915. More recently, the term has focused on a city's financial power and high technology infrastructure, with other factors becoming less relevant 10

  10. CHARACTERISTICS OF GLOBAL CITIES Centers of media and communications for alobal networks Dominance of the national region with great international significance High percentage of residents employed in the services sector and information sector High-quality educational institutions, including renowned universities, international student attendance, and research facilities Multi-functional infrastructure offering some of the best legal, medical, and entertainment facilities in the country High diversity in language, culture, religion, and ideologies. 12

  11. RANKINGS Global Economic Power Index In 2015, the second Global Economic Power Index, a meta list compiled by Richard Florida, was published by The Atlantic(distinct from a namesake list published by the Martin Prosperity Institute), with city composite rank based on five other lists. Global Power City Index The Institute for Urban Strategies at The Mori Memorial Foundation in Tokyo issued a comprehensive study of global cities in 2017. They are ranked based on six categories: economy,research & development, cultural interaction, livability, environment, and accessibility,with 70 individual indicators among them. The top ten world cities are also ranked by subjective categories including manager, researcher, artist, visitor and resident Global Power City top 10:1. London, 2. New York City, 3. Tokyo, 4. Paris, 5. Singapore, 6. Seoul, 7.Amsterdam, 8. Berlin, 9. Hong Kong, 10. Sydney 14

  12. EDGE CITY Edge city" is term that originated in the United States for a concentration of business, shopping, and entertainment outside a traditional downtown (or central business district) in what had previously been a residential or rural area X The term was popularized by the 1991 book Edge City: Life on the New Frontier by Joel Garreau, who established its current meaning while working as a reporter for The Washington Post. Garreau argues that the edge city has become the standardform of urban growth worldwide, representing a 20th-century urban form unlike that of the 19th-century central downtown. Other terms for these areas include suburban activity centers, megacenters, and suburban business districts. These districts have now developed in many countries 15

  13. GARREAU IDENTIFIED THREE DISTINCT VARIETIES OF THE EDGE CITY PHENOMENON: Boomers-The most common ty e, having developed incrementally around a shopping mall or highway interchange Greenfields Having been master-planned as new towns, generally on the suburban fringe Uptowns - Historic activity centers built over an older city or town (sometimes a satellite city) For example, within Northern Virginia, Tysons is a Boomer, Reston Town Center is a Greenfield, and the Rosslyn-Ballston Corridor is an Uptown. 17
