In 1950 New York and Tokyo were the only so called megacities; cities with more than 10m inhabitants.
By 1980 these were joined by Mexico City, Sao Paulo and Osaka.
In 2010 there were over 20 megacities spanning almost every continent.
Today, there are 32 megacities.
Urbanisation is happening faster than at any time in human history. Asia accounts for over half of today's megacities. By 2030 nearly 9% of the world's population will live in 41 megacities. But it's in Africa where some of the most rapid urbanisation will take place in the future.
