20 Most Populated Cities in the World


The latest United Nations studies confirm that the world population continues to increase and points the number to close to 7700 million people. Much more than 4 billion in 1974 but also much less than the 10 billion expected in 2057.

Since the industrial revolution that began in the mid-18th century, migration from the countryside to the cities has not ceased to invert the balance and bring the world population closer to large cities. This phenomenon occurs throughout the planet and if we look at the data of the 20 most populous cities in the world they host 5% of the total world population.

Increasingly, the exodus from the countryside to the city is growing, and currently of those 7700 million people, about 385 million, live in one of the 20 megacities of the planet. These are divided between 12 large cities in Asia, 4 in America, and 4 in Africa.
