The world-renowned American thinktank, Brookings Institution has brought out a new report called 2014 Global Metro Monitor Map. It compares growth in the world’s 300 largest metros on two key economic indicators: annualized growth rate of real GDP per capita and annualised growth rate of employment.

Here’s how Kolkata became India’s second-fastest growing metro:

Six Indian cities list made it to the list of 300 fastest-growing metros (growth rank for 2013-14): Delhi, Kolkata, Mumbai, Chennai, Hyderabad and Bangalore.

Their comparative rankings are explained in this infographic:

As far as GDP (in terms of purchasing power parity (PPP)) and population were concerned, there were no surprises: Delhi led in both.

But in terms of GDP growth per capita (from 2013 to 2014), Kolkata scored high.

Kolkata also came second among the Indian metros, when it came to growth in employment.
