According to the United Nations Population Division, the proportion of Asia's population living in cities has grown in the last 20 years by around a third to over 40 percent. In the last five years alone, the number of inhabitants in Asian cities has been increasing by about 100,000 a day. And this development will continue in the years to come. In China alone, experts predict that by 2025 there will be well over 200 cities with a population of over a million. 2011 there are just under 90, while Europe currently has 25 cities of that size.
