Gotham is a state of mind.
Gotham is the Megacity per Antonomasia.
Megacities are generally defined as those with more than 10 million inhabitants. Back in the early 1950s, there were only two on Earth - New York and Tokyo; by 2010, according to United Nations figures, this number had shot up to 24 - and by 2025, the UN predicts, there will be 39 of these supersized cities. These numbers tell a remarkable story about the way we are choosing to organise our lives but, look deeper into the data, and an equally fascinating trend reveals itself: the new urban areas are growing fastest not in the traditional powerhouses of Europe and America but in Asia and the "global south".In 2010, just nine of the world's megacities were located in Asia; scroll forward 15 years and 21 of the projected 39 megacities will be situated here, with the biggest growth in population expected to take place in the new or lesser-known cities in South and East Asia.
