Question 11. Concentric Circles Model - The Concentric Circles Model otherwise known as the Burgess Model is named after its creator Ernest Burgess in 1925. Burgess was a socialist who developed the a Chicago University and used Chicago as a case study to develop the model. This was the first model of its kind to explain the distribution of different social groups within cities and urban areas (s-cool.co.uk, 2014).Fig. 1.0 Burgess model showing different zones of social groups. (s-cool, 2014) Figure 1.0 shows the urban land use as concentric rings around the Central Business District (CBD) shown as Zone A. Zone B is the Transition Zone which contains mixed zones of residential and commercial buildings. Homes within Zone C are classified as working class residential homes or inner suburbs later known as inner city. In Zone D there are middle-class residential houses, generally of better quality. The last area is the upper class residential houses or commuter area which is further away from the CBD (Rodrigue, 2014).2. Sectoral Model – This model was created by Homer Hoyt in 1939 and suggested that social zones within a city expand outward into sectors that follow transportation links (Liu, 2009). The firm was based in Chicago, Hoyt could see that upper-class homes were being built favoring the sought-after Lake Michigan shoreline. This led him to develop sectoral theory. The CBD is the center of the model with the Transition Zone in a similar position to the Burgess model in Zone B. Lower middle class residential houses form a circle around Zone B and the CBD and extend to the outskirts of the urban area. Lower class homes are located near industrial areas and middle classes...... middle of paper......0) Expanding cities and transport: preliminary findings from Bristol, UK.
