American culture is based on cities and the urban landscape (particularly the skyscraper neighborhoods) maintains an outstanding role in popular culture.
Today, the majority of the United States live in cities, and the United States ranks third in the world in terms of urban population, in absolute value. More than 30% of Americans live in a metropolis of more than five million inhabitants. . These agglomerations are recent and are structured in networks.
The layout: The most common arrangement of American urban centers is the checkerboard layout. However, this plan may vary depending on the configuration of the place (eg Boston), the history of the city (Washington DC), etc. The plan on the board is neither a novelty nor an exception in modern times: the ancient cities (Alexandria, Pompeii) or medieval (the bastides) already applied this organization and other cities of the American continent adopted it in the seventeenth and eighteenth centuries. The orthogonal plane responds to the demands of speed and rationalization of space.
The great American cities have a similar structure and organization, which follows a concentric model:
1) The business center or financial center is an important concentration of skyscrapers that house offices, administrations, hotels, shops.
2) Intermediate neighborhoods They are located around the CBD and are made up of relatively old and low buildings, factories and warehouses.
3) The periphery or residential suburbs (suburbs) extend around the periphery and house the middle classes.
