The number of urban areas in the world with a population over one million has exploded since 1950. This map shows just how extreme that explosion has been.
On the map, you can see how in 1950 the world’s scant million-plus cities were heavily concentrated in western Europe, the northeastern United States, and Japan. Since then, not many new ones have popped up in those places, but the rest of the world has caught up big time.
By the 1980s, China, India, and southeast Asia are challenging the west’s dominance. By the turn of the millenium, the middle east and central Africa join the party. South America keeps up a slower but steady pace the whole time.
