The Center for Globalization and Strategy from Barcelona’s IESE Business School has unveiled its annual list of the world’s smartest cities. In its fifth year, the IESE Cities in Motion Index has calculated the performance scores for 165 cities across 80 countries based on an exhaustive rubric of economic and social indicators. Familiar global power centers have maintained their position at the top of the heap, while expanded categories of assessment have helped a few small cities advance their position drastically.
