Chicago is the third largest city of the USA. The whole agglomeration is inhabited by almost 10 million people, whereas the inner center is populated by over 2,5 million residents. Such a big city requires efficient management and functional administrative divisions. Modern housing – most of which was erected at the beginning of 20th century – makes it possible to move around the city in a convenient way. One of the basic Chicago means of transport is a fast city rail, however, it is important to remember the significance of famous yellow cabs, which inseparably belong to the city’s landscape.
