Multiple Nuclei Model By:Philip Chesney and Will Amsbaugh The Model 1. The multiple nuclei model is an economical model created by Chauncy Harris and Edward Ullman in 1945 2. This model describes the layout of a city, it is based off of Chicago 3. It says even though a city may have begun with a CBD, it will have other smaller CBDs develop on the outskirts of the city 4. If other CBDs develop on the outskirts of a city they would be around valuable housing areas to allow shorter commutes to the outskirts of the city Reasons for the Model Continued 1. Certain industrial activities require transportation facilities 2. Various combinations of activities tend to be kept apart 3. Other activities are found together to their mutual advantage 4. Certain facilities need to be placed in a certain area of a city, like the CBD requires convenient traffic systems, and many factories need an abundant source of water 5. Some events benefit from the adjacent distance like positions of factories and residence Placement of Classes 1. Low Class: Low class residential area are closer to the manufacturing jobs which tend to to be non-minimal skilled jobs. They also tend to have low wages which in turn lead to a low class residents. 2. Medium Class: Medium class residential area tends to be close to the cbd. It also has more space to spread out to support the population which are doing the skilled-labor jobs. 3. High Class: High class residential areas tend to be on the outskirts of the medium class residential area. The area is also touching the outlying business district. The jobs that the people in this district do are usually skilled labor and have high incomes. Fun Facts About The Model 1. This model, unlike some others, takes into account the varied factors of decentralization of North American cities 2. The distance decay theory can still be applied to this model, land value and population density decline with distance from the central places 3. Some criticism about the model: negligence of height of buildings, non- existence of abrupt divisions between zones, unawareness of inertia forces, no consideration of influence of physical relief and government policy, each zones displays a significant degree of internal heterogeneity and not homogeneity
