	The term ‘megacity’ refers to metropolitan areas with a total population of more than 10 million people. The definition of what constitutes a megacity generally refers to the population of an urban agglomeration, that is, it includes people living in the immediate suburbs outside of the established border of the city.

−	Megacities are a distinctly modern phenomenon, the proliferation of which has spread with the large-scale urbanisation that has occurred in many countries around the world. Whereas only 3% of the global population lived in cities in 1800, by the end of the 20th century that figure had risen to 47%. This figure is predicted to rise to more than 70% by the second half of the 21st century, a number made even more startling by the fact that the human population is expected to have increased by two billion by that point.	+	= When did megacities emerge? =
