European cities have emerged as the world's richest and most expensive places. By comparison, Indian cities are amongst the world's least expensive.
New Delhi and Mumbai are among the least expensive cities in the world, ranked 70th and 73rd positions, respectively.
Amongst Asia's most expensive cities, New Delhi ranks 41st, Mumbai 43rd, Chennai 44th, Bangalore 45th, Hyderabad 46th, Pune 47th, and Kolkata 49th.
The UBS survey of 73 international cities found that employees in Copenhagen, Zurich, Geneva and New York had the highest gross earnings. Living costs were calculated based on a survey of 154 items in total.

A survey by citymayors.com on the kind of salaries that Indians are paid when compared to the payscales in some other global cities is quite a revelation. The survey says that in New York or Zurich one would have to work for 9 hours to earn enough to buy an iPod nano, whereas in Mumbai you would have to work for 177 hours to be able to afford the gadget!
