This year's edition of the World Urban Areas Report covers more than a thousand of the largest cities in the world, from Tokyo (pop. 37,000,000), right down to tiddlers like 850th-ranked Leicester (Pop. 534,000): all 1,009 cities, in fact, with a population of half a million of more. Here are the top 10.
In the year 2000 there were 39 cities with a population of more than 5 million inhabitants, 2/3 of which were in the developing countries. This was a population of 225 million people, not even 5% of the worldâs population. Today we have about 400 million people living in the largest cities on the planet â still far from the majority of the now more than half of the worldâs population living in cities. And perhaps the majority of people on this planet may never live in one of these megacities.
