Are you a world traveler, or just a student of geography? Either way, you're probably familiar with the major cities of the world. Take this quiz to find out how much you really know about the world's metropolises.
The world's biggest city, by population, is Shanghai, in China. More than 24 million people live there. But Shanghai isn't the only city that is bursting at the seams. In fact, there are roughly 500 cities throughout the world with populations of more than one million people. Shanghai may be overrun (not literally, lol) by Mexico City, Mexico very soon since Mexico City's population is growing at an astounding rate.
Although these megacities come with their own sets of problems and challenges, they also serve as hubs for the development of art, music, medicine, culture, and more. For instance, take New York, as the very first megacity (New York had grown to house more than 10 million people by 1930), and Tokyo as the second megacity (more than 10 million inhabitants by 1950), and you'll see how cities grow.
