A Growing Percentage Of The World's Population Lives In Urban Areas
Gbogbo ọrọ náà
In 1975 the world had eight cities of more than ten million people. Today it has more than thirty, and most of them are in Asia. Behind that headline sits the largest migration in human history, still in progress, and it is running at completely different speeds on different continents.
This lesson teaches you to read the urbanisation curve: which countries are on the steep part, which have levelled off, and which are now sending people back out through suburbanisation and counter-urbanisation. You will learn what drives the rate of urbanisation, why megacities emerge where they do, and what goes wrong when a city grows faster than anyone can plan for it.
