The study has been carried out by the Institute for Interdisciplinary Physics and Complex Systems (UIB-CSIC), in collaboration with the University of Marseille. More than 21 million tweets have made Rome the most attractive city in the world , followed by Paris, Barcelona, Lisbon and Berlin.
According to the authors, the main objective of the research, which has focused on 58 cities among the 100 most populated in the world , was to contribute information to the geographical debate on the leadership of some cities in relation to others with a new parameter: mobility.
According to the tweets issued, the world ranking of the most influential cities are New York, London, Paris, Tokyo and Singapore. Madrid is in position 10 and Barcelona in position 11. At the European level, the most influential cities are London, Paris, Moscow, Barcelona and Berlin.
In addition, researchers have been able to show that the influence or attraction of cities is different depending on the study context. For example, Miami is the second most influential city in North America , while if influence in the US is studied, it goes to sixth place.
