Today, more than half of the world’s population lives in cities, and the world continues to urbanize rapidly. By 2050, two-thirds of the world’s population will live in urban areas, according to the United Nations.
The A.T. Kearney Global Cities Index (GCI) ranks 125 cities according to 27 metrics across five dimensions, including business activity, human capital, information exchange, cultural experience, and political engagement. The Index is designed to provide insights into the global reach, performance, and level of development of the world's largest cities. It allows for the comparison of diverse cities - such as New York and Shanghai - to help draw unique conclusions about their shared strengths and core differences.
Global Cities Outlook 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.
A.T. Kearney's Global Cities identifies a set of cities that rank in the top 25 on both the Index and Outlook - called the 'Global Elite'. 15 cities qualify this year, and they are all well-known hubs of culture and politics, as well as true global economic hubs. Combined, they average 8.8 million in population and account for $7.3 trillion in GDP - or about half of the GDP of all 55 high-income cities measured by Global Cities.
