The data given here in this article clearly states that the growth parameter is in regards to the economical growth. It means the revenue earned by means of Tax & duty & others by the goverment paid by the respective citizen and the corporates. Mumbai is offcourse the economical capital of India but its growth rate per-se last year is less than few other cities. Thats what is mentioned here. Mumbai's or Bangalore's growth rate of 10 is higher than many cities of USA. Does that mean Mumbai or Bangalore is larger & better than those US cities? So please stop mud-slinging here. Every city has its own charm. Look at those and be happy. Mera Bharat Mahan.
