Overview: Today we’re going to take a closer look at cities, examine how these large complex structures are organized, and identify patterns and differences in land use around the world. We'll begin with a quick recap of Central Place Theory, then we'll show you how the Concentric Zone Model can approximate the development of Chicago in the United States. Then, we'll take a closer look at colonial port cities, the development of industrial zones and financial districts, and the patchwork of immigrant communities that often developed around them in cities such as Boston in the United States. And finally, we will end our episode with a look at the layout of some North African cities that are in earthquake-prone areas with hot and dry climates such as in Fez, Morocco.
