You do not hear this often but cities with population of more than ten million people are called megacities. If you already know the top ten (Tokyo, Jakarta, New Delhi, Manila, Seoul, Shanghai, Krachi, Beijing, New York and Guangzhou) megacities in the world, it can benefit you if you know the rest of the list.

The World Urban Areas Index released its newest edition of the top twenty megacities. The Index was made possible by Demographia. Here’s the other ten megacities in the world:

• Sao Paulo: Sao Paolo is the number eleventh megacity in the world with 20.3 million people.
• Mexico City: Mexico is the number twelfth megacity in the world with 19.4 million people.
• Mumbai: Mumbai has now 17.7 million people making it the thirteenth megacity in the world.
