Criteria

Competing groups have developed multiple alternative methods to classify and rank ''world cities'' and to distinguish them from ''non-world cities''. Although there is a consensus upon leading world cities,GaWC Research Bulletin 5

the chosen criteria affect which other cities are included. Selection criteria may be based on a ''yardstick value'' (e.g., if the producer-service sector is the largest sector then city is a world city) or on an ''imminent determination'' (if the producer-service sector of city is greater than the combined producer-service sectors of other cities then city is a world city.) Cities can fall from ranking, as in the case of cities that have become less cosmopolitan and less internationally renowned in the current era.


Characteristics

Although criteria are variable and fluid, typical characteristics of world cities are: * A variety of international financial services, notably in FIRE economy, finance, insurance, real estate, banking, accountancy, and marketing * Headquarters of several multinational corporations * The existence of financial headquarters, a stock exchange, and major financial institutions * Domination of the trade and economy of a large surrounding area * Major manufacturing centres with port and container facilities * Considerable power (international relations), decision-making power on a daily basis and at a global level * Centres of new ideas and innovation in business, economics, culture, and politics * Centres of media and communications for global networks * Dominance of the national region with great international significance * High percentage of residents employed in the services sector and quaternary sector of the economy, 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


Rankings

Global city rankings are numerous, with one study suggesting as many as 300. Most ranked cities are in North America and Europe. New York City, New York, London, Tokyo, and Paris, notably four of the most significant metropolises, have been ranked in top four positions in Global Cities Index and Global Power City Index since both indices' inception in 2008, with New York and London exclusively in top two positions.


GaWC study

Jon Beaverstock, Richard G. Smith (geographer), Richard G. Smith, and Peter J. Taylor established the Globalization and World Cities Research Network (GaWC). A roster of world cities in the ''GaWC Research Bulletin 5'' is ranked by their connectivity through four "advanced producer services": accountancy, advertising, banking/finance, and law. The GaWC inventory identifies three levels of global cities and several sub-ranks,The World According to GaWC
". GaWC. Retrieved 21 November 2012.
although the authors caution that "concern for city rankings operates against ''the spirit of the GaWC project''" (emphasis in original). The 2004 rankings added several new indicators while continuing to rank city economics more heavily than political and cultural factors. The 2008 roster, similar to the 1998 version, is sorted into categories of Alpha world cities (with four sub-categories), Beta world cities (three sub-categories), Gamma world cities (three sub-categories), and cities with High sufficiency and Sufficiency presence. The cities in the top two classifications in the 2018 edition are as follows:


Alpha ++

* London * New York City, New York


Alpha +

* Beijing * Dubai * Hong Kong * Paris * Shanghai * Singapore * Tokyo


Global City Competitiveness Index

In 2012, the Economist Intelligence Unit (Economist Group, The Economist Group) ranked the competitiveness of global cities according to their demonstrated ability to attract capital, businesses, talent, and visitors.


Global Cities Index

In 2008, the American journal ''Foreign Policy'', working with the 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 "the 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." The ranking is based on 27 metrics across five dimensions—business activity, human capital, information exchange, cultural experience, and political engagement—and was updated in 2010, 2012, 2014, 2015, 2016, 2017, 2018, and 2019. Since 2015, it has been published with a separate index, the Global Cities Outlook, which is a projection of a city's potential based on rate of change in 13 indicators across four dimensions: personal well-being, economics, innovation, and governance. The top ranked cities in 2020 are: as follows: * 2020 Global Cities Index: # New York City # London # Paris # Tokyo # Beijing # Hong Kong # Los Angeles # Chicago # Singapore # Washington, D.C.


Global Cities Initiative

A study by Brookings Institution conducted in 2016 introduced its own typology, sorting global cities into seven categories: Global Giants, Asian Anchors, Emerging Gateways, Factory China, Knowledge Capitals, American Middleweights, and International Middleweights The Global Giants classification includes wealthy, extremely large metropolitan areas that are the largest cities in developed nations. They are hubs for financial markets and major corporations, and serve as key nodes in global flows of capital and of talent. * London * Los Angeles * New York City * Keihanshin, Osaka-Kobe * Paris * Tokyo


Global City Lab

An analysis report compiled by the Global City Lab of the Global Top 500 Cities was released in New York 27 December 2019. The top 10 cities by Brand valuation, brand value were as follows: # New York City # London # Tokyo # Paris # Los Angeles # Sydney # Berlin # Singapore # Hong Kong # Toronto


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 2019. They are ranked in six categories: economy, research and 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: # London # New York City # Tokyo # Paris # Singapore # Amsterdam # Seoul # Berlin # Hong Kong # Sydney

The Wealth Report

"The Wealth Report" (a global perspective on prime property and wealth) is made by the London-based estate agent Knight Frank LLP and the Citi Private Bank. The report includes a "Global Cities Survey", evaluating which cities are considered the most important to the world's HNWIs (high-net-worth individuals, having over $25 million of investable assets each). For the Global Cities Survey, Citi Private Bank's wealth advisors, and Knight Frank's luxury property specialists were asked to name the cities that they considered the most important to HNWIs, in regard to "economic activity", "political power", "knowledge and influence", and "quality of life". * Most important cities to UHNWIs in 2015: # London # New York City, New York # Hong Kong # Singapore # Shanghai # Miami # Paris # Dubai # Beijing # Zurich * Most important cities to UHNWIs in 2025: # New York City, New York # London # Singapore # Hong Kong # Shanghai # Beijing # Miami # Dubai # Paris # Zurich
