20.2 Urbanization  (Page 4/24)

Urbanization around the world

As was the case in America, other coronations experienced a growth spurt during the Industrial Era. The development of factories brought people from rural to urban areas, and new technology increased the efficiency of transportation, food production, and food preservation. For example, from the mid-1670s to the early 1900s, London increased its population from 550,000 to 7 million (Old Bailey Proceedings Online 2011). The most recent phenomenon shaping urbanization around the world is the development of postindustrial cities whose economic base depends on service and information rather than the manufacturing of industry. The professional, educated class populates the postindustrial city, and they expect convenient access to culturally based entertainment (libraries, museums, historical downtowns, and the like) uncluttered by factories and the other features of an industrial city. Global favorites like New York, London, and Tokyo are all examples of postindustrial cities. As cities evolve from industrial to postindustrial, gentrification becomes more common. The practice of gentrification    refers to members of the middle and upper classes entering city areas that have been historically less affluent and renovating properties while the poor urban underclass are forced by resulting price pressures to leave those neighborhoods. This practice is widespread and the lower class is pushed into increasingly decaying portions of the city.

Theoretical perspectives on urbanization

As the examples above illustrate, the issues of urbanization play significant roles in the study of sociology. Race, economics, and human behavior intersect in cities. Let’s look at urbanization through the sociological perspectives of functionalism and conflict theory. Functional perspectives on urbanization focus generally on the ecology of the city, while conflict perspective tends to focus on political economy.

Human ecology is a functionalist field of study that focuses on the relationship between people and their built and natural physical environments (Park 1915). Generally speaking, urban land use and urban population distribution occurs in a predictable pattern once we understand how people relate to their living environment. For example, in the United States, we have a transportation system geared to accommodate individuals and families in the form of interstate highways built for cars. In contrast, most parts of Europe emphasize public transportation such as high-speed rail and commuter lines, as well as walking and bicycling. The challenge for a human ecologist working in American urban planning would be to design landscapes and waterscapes with natural beauty, while also figuring out how to provide for free flowing transport of innumerable vehicles—not to mention parking!

The concentric zone model    (Burgess 1925) is perhaps the most famous example of human ecology. This model views a city as a series of concentric circular areas, expanding outward from the center of the city, with various “zones” invading (new categories of people and businesses overrun the edges of nearby zones) and succeeding (after invasion, the new inhabitants repurpose the areas they have invaded and push out the previous inhabitants) adjacent zones. In this model, Zone A, in the heart of the city, is the center of the business and cultural district. Zone B, the concentric circle surrounding the city center, is composed of formerly wealthy homes split into cheap apartments for new immigrant populations; this zone also houses small manufacturers, pawn shops, and other marginal businesses. Zone C consists of the homes of the working class and established ethnic enclaves. Zone D consists of wealthy homes, white-collar workers, and shopping centers. Zone E contains the estates of the upper class (exurbs) and the suburbs.
