Bengaluru is the most dynamic city in the world, beats Silicon Valley

The fellow residents of Koshy's, Ramachandra Guha, Nandan Nilekani and Kiran Shaw might not know this, but their city has one more thing to be proud of.

Bangalore has been ranked the world's most dynamic city on an index that captures a city's economic changes and its ability to sustain it. Hyderabad also makes it to the Top 10, ahead of London, and Chennai and Pune to the Top 20, but environmental factors push Delhi and Mumbai to the 23rd and 25th spots. The real estate services firm JLL's annual City Momentum Index (CMI) ranks cities across the world by the speed of change of the city's economic and real estate market and the city's potential to sustain this dynamism. The index is intended to "identify change and highlight which cities or metropolitan areas may be best at positioning themselves to compete in today's ever-changing economic landscape," Jeremy Kell, research director at JLL, wrote in a blog post for the World Economic Forum.

The index has 42 ingredients across three key areas; socio-economic factors including GDP, population, air passengers, corporate headquarters and foreign direct investment account for 40% of the ranking. Commercial real estate momentum measured through changes related to construction, rents, investment and transparency in the office, retail and hotel sectors accounts for another 30%. Innovation capacity and technological prowess, access to education and environmental quality accounts for the remaining 30% of the index.
