Overloaded infrastructure, cultural diversity, and a booming job market are common characteristics in these large urban centers. But what are these super-populous cities in the world, and what is the daily life like for those who live in them? *The numbers refer to metropolitan areas, that is, areas that encompass the main metropolis and economically and socially connected neighboring municipalities.

1. Tokyo, Japan – 37 million inhabitants

The Tokyo metropolitan area is the most populous city in the world, combining advanced technology, tradition, and extremely efficient infrastructure.
