The institution responsible for classifying cities as global or not is Loughborough University (London) at an early stage and further refined by the Globalization and World Cities Study Group & Network.
Currently, more than 50 global cities are recognized on the planet, divided into three groups, according to the degree of influence and global importance. Europe is the continent with the most global cities.
