| Multiple Nuclei Model | Shows how the city doesn’t grow around a single CBD or downtown, but instead develops from multiple nodes that make the city. This model was created because og models like the Concentric Rings Model didn’t completely match up with how modern cities grew. |
| Harris and Ullman (United States) | Developers of Multiple Nuclei Model |
| nodes | Are functional regions that draw people in and bring people from different social classes into the node. Certain nodes will bring people together regardless of their social class or income level. |
| Incompatible | smoke stacks represent industries where the rich/elite don’t live near since they don’t want to live in loud, polluted, or crowded areas (opposite). This shows how certain places or activities don’t mix well, which is why certain things are further away. |
| Sector Model | a model showing how cities grow in wedge shaped sections that spread out from the center downtown (CBD). |
| Hoyt (United States) | Developer of sector model |
| transportation/industry (2)- sector model | a section that's developed along transportation routes like highways, roads, rivers, or railroads. Factories and industries are also located here because it makes transporting them easier. |
| Low-Income Location (3)- sector model | right next to the sector that has transportation or industry for lower class people who rely on close, public transportation like buses since they can’t afford cars. |
| Middle-Income Location (4)- sector model | historically, this sector tends to fill in and showcase that the middle income class is the largest and fills in the blank spaces. |
| High-Income Location (5)- sector model | further out of the actual city landscape, and able to travel right through to the CBD and not interact with other areas (Carmel, Fishers). (Concentric Rings Model) |
| Concentric Rings Model | shows the growth of cities in circles (rings) from the central downtown. Each ring represents something different about income level, housing type, and land use as people move further outwards. |
| Burgess | Developer of concentric rings model |
| 1st Ring (Central Business District (CBD)) | biggest financial transactions (banks, financial institutions, wall street, stock markets). Many homeless ppl live here because of gov. assistance like soup kitchens. the wealthy/elite are also here because they can afford huge and expensive apartments. |
| 2nd Ring (zone of Transition) | land section with factories, warehouses, docks, ports, and oldest/lowest income housing. This area is known for having higher crime rates and bad living conditions. |
| 3rd Ring (blue collar residences) | Historically, people who worked in different service jobs/working class would wear blue collared shirts. Many people live in older or smaller houses that aren’t necessarily in as poor shape. |
| 4th Ring (medium income housing) | historically, larger class with average income, house size, and age of house. |
| 5th Ring (high income commuter zone) | rich and elite people who want to live in the outer layer suburbs. The commuter zone is when people commute downtown and back for work and money without interacting with other zones. |
| European Model | Small to medium, dense cities with historic centers and crowded plazas acting like a CBD. Narrow streets built before cars, tall churches/government buildings, and heavy use of public transportation instead of driving. |
| De Blij | Developer of Sub-Saharan African City Model |
| Colonial CBD | Downtown built by European colonizers with organized blocks, government buildings, and strong infrastructure. It still has better services and wealth today because of historical advantages, investment and roads that run through it. |
| Traditional CBD | A lot of post colonialism (oldest part of town) that’s mainly powered by native African people. They have newer technologies and better communications helping them connect globally and become more modernized. |

| impoverished/informal satellite townships (sub-saharan model) | located on the outskirts with informal townships that live near each other for protection, animals, or thieves. They mostly live in scattered tents (not traditional neighborhoods), with limited government services, water, sanitation, or electricity. |
| roadways (sub-saharan model) | tend to run through the colonial CBD since it was designed to be the main economic center historically. Makes it difficult for the traditional CBD to develop since its harder for them to get goods out of the city and use the roads for their own benefit. |
| Borchert’s Model of Urban Evolution | A model that explains how cities in the United States developed and grew over time based on major transportation technologies, such as railroads, cars, and airplanes, with each stage (epoch) shaping urban patterns differently. |
| Griffin-Ford | Latin America Model Developer |
| Periferico (Commuter Zone) | modified roadway that ultimately allows the middle to upper class to travel the city easily. You can also see clear cut distinctions of upper/middle class to lower class on each side. (latin america) |
| Favelas (Brazil)/Barrios = Disamenity Sector | Squatter settlements built from scraps on steep, unstable hills. Homes are crowded, lack inspections, water, and sanitation, with high crime and pollution. Core counties rarely have areas this poor or dense. (latin america) |
| Zone of Maturity | much older housing in fairly decent shape where the rich/elite used to live, but now where most middle class people are. (latin america) |
| Zone of Situ Accretion | An area where a lot of the homes or buildings are incomplete/unfinished since they don’t have the best access to resources, and not much city planning or contracts are done. |
| stratification | The division of society into different social classes based on wealth, power, or status. |
| mall/spine | Parks, malls, and nicer housing connect the wealthy areas to the CBD. Rich residents shop at the mall and travel here, keeping high-end commerce and services separated from lower-income areas. |
| Harris | Galactic City Model (peripheral model) developer |
| beltway | a major highway that wraps around a city for transportation, allowing people to go anywhere in the city pretty quickly without the typical congestion. (galactic city model) |
| decentralization | Cities move people, businesses, and services out of the crowded CBD to the outskirts, creating space for malls, stadiums, and new development. Sometimes incentives like tax breaks and punishment styles are made to encourage this. |
| McGhee | Southeast Asia Model develper |
| port zone | Southeast Asian cities grow around water-based trade. This area handles importing and exporting goods, with cranes, containers, and shipping infrastructure for international commerce. |
| ACZ (alien commercial zone/other Asian states) | these areas are dominated by Asian countries who came into that area and set up shops, businesses, and housing. In 2006, the number one country in the ACZ was China because they had the most amount of power (Chinese merchants). (SE Asia model) |
| WCZ (western commercial zone) | colonialism from Western Europe and USA putting up these zones to set up better environments and get whatever they need. (SE Asia Model) |
| New Industrial State | after decolonization, when people/cities have gotten enough investment to finally move on from just using cash crops (factories & industrialization). (SE Asia model) |
