The capital of Mexico, also called the Federal District, Mexico City has a metropolitan area population of 21.2 million, though just under 9 million of those people live in the city proper, making it the country's most population dense city.

Mexico is also growing rapidly, and its population is expected to surpass Japan's soon, which would make Mexico one of the top ten most populous countries in the world.
