This interactive map from the BBC tracks growth and urbanization in global cities from 1955 up through 2015.
As time goes on, more and more mega cities develop, and the urban populations of regions sharply grow.
"This map uses the Gall-Peters projection, rather than the Gall projection usually used by the BBC. All flat, rectangular maps of the Earth contain some distortion of land size, shape and distance between countries. The Peters Projection minimises the distortion to land area, enabling the best comparison between regional populations and the size of the land masses they live on."
