Figure 10.1: Urbanized population in the world. This map indicates the percentage of a country’s population that lives in urban areas, but this information must be used cautiously due to different international definitions of the word city. Notice that, despite recent rapid urbanization in countries of the developing world, many of these countries have less-urbanized populations than countries of the developed world.
