IntroductionSince the development of modern cities, geographers have broken down city maps into simple planning models to facilitate land use studies. However, as technology and transportation have made significant advances, many cities have begun to change their urban form and land use. Throughout this essay, I will present and compare the concentric zone model with the multi-core model and their relevance to the modern and postmodern city. Concentric Zone ModelOne of the first urban development models created was the concentric zone model. It was based on the city of Chicago in the 1920s, when it was a modern industrial city focused on manufactured goods and production. At that time, most people still relied on public transportation because the availability of private cars was not common. It is a model where areas are divided by concentric circles. (Bunyi, J. 2010)Figure 1: Concentric Zone Model (SSC Leichhardt Geography Blog, 2011)The zones are divided with the central business district (CBD) in the center, where most businesses are located as it has a transportation system developed to accommodate commuters. This area being very accessible, many shops and restaurants are built there. The industrial zone is located outside the CBD, to take advantage of nearby transport hubs, as well as the nearby labor market. The transition zone is home to most of the working class because it is close to factories, which reduces transportation costs. The standard of living in this region is generally poor due to pollution and population. (Pacione, M. 2005)The established residential area was dominated by the working class who were able to move away from the previous area. This region is reasonably close to the CBD but quite distant... middle of paper ...... the CBD being redeveloped into a mixed-use district shows how concentric zoned model cities can evolve into a multi- nuclear. (East Perth Redevelopment Authority, 2007) Conclusion A concentric zone model town differs from a multi-core model town because they function differently economically and socially. The first is based on industrial cities, heavily dependent on the production of manufactured goods and exports, where the wealthy can afford to stay as far away from factories and the CBD. The latter better explains a postmodern society where the economy is diversified and has multiple centers of growth, with more emphasis on services and consumption than on manufacturing and production. Therefore, its high-end residential areas are close to the CBD, as the redevelopment of industrial areas provides a desirable area with high standards of living and low travel costs..
