According to the Economist Intelligence Unit list of top 120 HotSpot global cities, 12 American cities make the cut, led by New York City. The first Indian city that figures on the list is Delhi at #68, edging out Mumbai at #70 and Bangalore at #79.
Other Indian cities on the list are Ahmedabad at 92, Pune at 97, Hyderabad at 98, Chennai at 105 and Kolkata at 106. Tehran, Iran is the last one listed at 120.
What this means:
One has to take any such list with a grain of salt. For example Pune traffic is so horrific at any time of the day (with few or no limited access highways in the city), I am surprised how they ranked it ahead of Hyderabad. Also Ahmedbad is a great city but am not sure I would rank it ahead of Pune, or Hyderabad. For many, many executives Mumbai leads in India no matter what, because they HAVE to be there for any kind of success in India.
