A.T. Kearney: Global Cities Index

The Global Cities Index provides a comprehensive ranking of the leading global cities from the world. It is designed to track the way cities maneuver as their populations grow and the world continues to shrink. The assessment is based on a country's economic standing, globalization rate, human capital, information and technology, cultural experience, and political engagement. The complete rankings, information about methodology, and expert analysis are all provided on the site. The index updates every year. Downloads in multiple file formats are available.
