Notice that both high cost residential areas (Zone 5 above) and Low-class residential (Zone 3 above) tend to remain within their respective sectors, both following some corridor of transportation (railway, river, highway, etc.). Similar land uses and socioeconomic groups cluster in pie shaped sectors radiating outward from a central business district, usually along transportation corridors. Therefore Zone 2 (Zone in Transition) contains poorer residents, industry, and warehouses while Zone 3 (Commuter Zone) contains homes for the wealthy. The further one moves from the CBD, the greater the wealth because only more wealthy people (according to this model) can afford to commute into the CBD every day. In this model, the city grows out from a Central Business District (CBD) in a series of concentric rings each with different land uses based on level of income. High-class residential zones stem from the center, middle-class zones are in inner city areas and in suburbs, and low income zones are in the periphery The model contains elements of Latin American culture and imprints of colonization and globalization.Įthnicities and types of CBDs change in rings/sectors as you travel further from the center, colonial CBD. The suburban regions were functionally tied to a mixed-use suburban downtown, or mini-CBD, with relative independence from the original CBD. The model explains and predicts changing urban growth patterns as the automobile became increasingly prevalent and large suburban "realms" emerged. Certain areas of the city are more attractive for various activities, originally because of an environmental factor or even by mere chance.Īccording to the multiple nuclei model, a city is a complex structure that includes more than one center around which activities revolve The city develops in a series of sectors, not rings. Therefore all three models divide cities into zones each with similar populations or similar land uses.Ī city grows outward from a central area in a series of concentric rings, like the growth of a tree. All were based primarily on the city of Chicago and all are based on the observation that most people prefer to live near others with whom they share similar characteristics. QR Challenge: APHUG Urban Models QuestionĬoncentric/Sector/Multiple Nuclei: These three models attempt to describe and predict urban land use and urban growth in North American cities.
