A global city (also called world city) is a city deemed to be an important node point in the global economic system. The concept comes from geography and urban studies and rests on the idea that globalization can be understood as largely 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 most complex of these entities is the "global city," whereby the linkages binding a city have a direct and tangible effect on global affairs through socio-economic means.^[1] The terminology of "global city", as opposed to megacity, is thought to have been first coined by Saskia Sassen in reference to London, New York and Tokyo in her 1991 work The Global City,^[2] though the term "world city" to describe cities which control a disproportionate amount of global business dates to at least Patrick Geddes' use of the term in 1915.^[3]

Characteristics

Global City or world city status is seen as beneficial, and because of this many groups have tried to classify and rank which cities are seen as 'world cities' or 'non-world cities'.^[3] Although there is a consensus upon leading world cities,^[4] the criteria upon which a classification is made can affect which other cities are included.^[3] The criteria for identification tend either to be based on a "yardstick value" ("e.g. if the producer-service sector is the largest sector, then city X is a world city")^[3] or on an "imminent determination" ("if the producer-service sector of city X is greater than the producer-service sector of N other cities, then city X is a world city").^[3]

The characteristics sometimes chosen include

• International, first-name familiarity; whereby a city is recognized without the need for a political subdivision. For example, although there are numerous cities and other political entities with the name Paris or variations on it, one would say "Paris", not "Paris, France".
• Active influence on and participation in international events and world affairs; for example, Washington, Berlin, Brussels are major capitals of influential nations or unions.
• A fairly large population (the centre of a metropolitan area with a population of at least one million, typically several million).
• A major international airport that serves as an established hub for several international airlines.
• An advanced transportation system that includes several highways and/or a large mass transit network offering multiple modes of transportation (rapid transit, light rail, regional rail, ferry, or bus).
• In the West, several international cultures and communities (such as a Chinatown, a Little Italy, a Tehrangeles or other immigrant communities); for example, New York City, Los Angeles, Toronto, Chicago, San Francisco, São Paulo and Vancouver. In other parts of the world, cities which attract large foreign businesses and related expatriate communities; for example, Hong Kong, Moscow, Shanghai, Singapore and Tokyo.
• International financial institutions, law firms, corporate headquarters, international conglomerates, and stock exchanges (for example the World Bank, or the New York Stock Exchange) that have influence over the world economy.
• An advanced communications infrastructure on which modern trans-national corporations rely, such as fiberoptics, Wi-Fi networks, cellular phone services, and other high-speed lines of communications.
• World-renowned cultural institutions, such as museums and universities.
• A lively cultural scene, including film festivals (such as the Berlinale or the Toronto International Film Festival), premieres, a thriving music or theatre scene (for example, West End theatre and Broadway); an orchestra, an opera company, art galleries, and street performers.
• Several powerful and influential media outlets with an international reach, such as the BBC, Reuters, The New York Times, or Agence France-Presse.
• A strong sporting community, including major sports facilities, home teams in major league sports, and the ability and historical experience to host international sporting events such as the Olympic Games, Football World Cup, or Grand Slam tennis events.

Studies

2004 GaWC studies

One of the first attempts to define, categorize, and rank global cities was made in 1999 by the Globalization and World Cities Study Group and Network (GaWC) based at the geography department of Loughborough University. The roster was outlined in the GaWC Research Bulletin 5 and ranked cities based on their provision of "advanced producer services" such as accountancy, advertising, finance, and law.^[4] The GaWC inventory identifies three levels of global cities and several sub-ranks. This roster generally denotes cities in which there are offices of certain multinational corporations providing financial and consulting services rather than denoting other cultural, political, and economic centres.

Another attempt to redefine and re-categorise leading global cities was made by GaWC in 2004. This new roster acknowledged several new indicators but still ranked economics ahead of political or cultural importance. The 2004 roster is reproduced below:

Global Cities^[5]

2008 Foreign Policy Ranking

In October 2008, the American journal Foreign Policy, in conjunction with consulting firm A. T. Kearney and the Chicago Council on Global Affairs, published a ranking of global cities, based on consultation with Saskia Sassen, Witold Rybczynski, and others. Foreign Policy noted that "[t]he world’s biggest, most interconnected cities help set global agendas, weather transnational dangers, and serve as the hubs of global integration. They are the engines of growth for their countries and the gateways to the resources of their regions."^[6]

The rankings are based on the evaluation of 24 metrics in five areas: business activity, human capital, information exchange, cultural experience, and political engagement. The top thirty of the 60 cities ranked were:

Rank	City	Best category (position in that category)
1	New York City	Business Activity and Human Capital (1st)
