#AP Human Geography: City Models - The Night Before 🌃

Hey there, future geographer! Let's get these city models locked down. Remember, it's all about understanding why cities look the way they do. We're not just memorizing shapes; we're exploring the forces that shape urban life. Let's dive in!

#Introduction to City Models

City models are like lenses 👓 that help us see the patterns of urban growth and development. They're not perfect, but they give us a framework to understand the complex social, economic, and spatial organization of cities. Think of them as simplified maps of how cities evolve. They help us analyze:

• How different social and economic groups are distributed
• How various parts of a city are connected
• The impact of planning and policy decisions on urban growth

#Why are City Models Important in APHuG?

• Analytical Tool: They help us identify trends and patterns in urban development that aren't always obvious.
• Policy Impact: They inform policymakers about the consequences of planning decisions.
• Understanding Change: They explain how cities evolve over time, adapting to new challenges and opportunities.

Let's explore the main models:

• Concentric Zone Model
• Hoyt Sector Model
• Multiple Nuclei Model
• Peripheral Model - “Edge Cities”

#Concentric Zone Model

#The Basics

• Also Known As: Burgess Model or Chicago School Model
• Concept: Cities grow outward from a central business district (CBD) in concentric circles.
• Developed By: Sociologist Ernest Burgess in the 1920s.

#Key Features

1. Central Business District (CBD): The heart of the city, with commercial activities and high land values.
2. Transition Zone: Surrounding the CBD, characterized by older buildings, poverty, and social issues.
3. Working-Class Homes: Modest housing for factory workers and other blue-collar employees.
4. Middle-Class Homes: More spacious housing for white-collar workers and families.
5. Commuter Zone: The outer ring, with suburban areas and residential communities.

#Strengths

• Simple and easy to understand.
• Good for explaining the basic spatial organization of early 20th-century cities.

#Weaknesses

• Overly simplistic: Doesn't account for complex factors like transportation or physical geography.
• Doesn't consider racial and ethnic segregation.
• Not applicable to all cities, especially those outside the US.

#Hoyt Sector Model

#The Basics

• Concept: Cities grow in sectors or wedges, radiating out from the CBD along transportation routes.
• Developed By: Economist Homer Hoyt in 1939. * Key Idea: Transportation corridors influence urban growth.

#Key Features

1. CBD: The central business district remains the core.
2. Industrial Sector: Located along transportation routes, such as railways or rivers.
3. Low-Income Residential: Often located near industrial areas.
4. Middle-Income Residential: Extends outward from the CBD, often along major roads.
5. High-Income Residential: Located in the most desirable areas, often away from industry.

#Strengths

• Recognizes the importance of transportation in shaping urban growth.
• More realistic than the concentric zone model.

#Weaknesses

• Still somewhat simplistic: Doesn't account for multiple activity centers.
• May not apply well to cities with complex topography.

#Multiple Nuclei Model

#The Basics

• Concept: Cities develop around multiple centers or nuclei, each with its own function.
• Developed By: Geographers Chauncy Harris and Edward Ullman in 1945. * Key Idea: Cities are complex and polycentric.

#Key Features

1. Multiple Nuclei: Various centers of activity, such as industrial parks, shopping malls, and universities.
2. Specialized Districts: Each nucleus attracts related activities and land uses.
3. Decentralization: Growth is not solely focused on the CBD.

#Strengths

• More realistic than the concentric or sector models.
• Accounts for the complexity of modern cities.

#Weaknesses

• Can be difficult to apply to older, more compact cities.
• May not fully explain the dynamics of social segregation.

#Peripheral Model - “Edge Cities”

#The Basics

• Concept: Focuses on the growth of edge cities on the outskirts of metropolitan areas.
• Coined By: Journalist Joel Garreau in 1991. * Key Idea: Decentralization of jobs and population to suburban areas.

#Key Features

1. Location: Located along major transportation corridors, such as highways and airports.
2. Mix of Uses: Include residential, commercial, and industrial areas.
3. Car Dependent: Often lack public transportation.
4. Self-Contained: Offer a range of amenities and services.

#Strengths

• Explains the growth of suburban areas in the late 20th and early 21st centuries.
• Highlights the impact of car culture on urban development.

#Weaknesses

• Can contribute to urban sprawl and environmental issues.
• May exacerbate social inequalities.

#Summary of City Models

• Concentric Zone Model: Circles outward from the CBD.
• Hoyt Sector Model: Wedges along transportation routes.
• Multiple Nuclei Model: Multiple centers of activity.
• Peripheral Model: Edge cities on the outskirts.

#Final Exam Focus 🎯

#High-Priority Topics

• Understanding the core concepts of each model.
• Applying the models to real-world cities and scenarios.
• Recognizing the limitations of each model.
• Analyzing how transportation and other factors influence urban growth.

#Common Question Types

• Multiple Choice: Identifying the main features of each model, applying models to scenarios, and recognizing their limitations.
• Short Answer: Comparing and contrasting different models, explaining how a city's development fits a particular model, and analyzing the impact of urban planning on city models.
• Free Response: Analyzing a city's spatial organization using one or more models, evaluating the effectiveness of urban planning strategies, and discussing the social and economic implications of different urban development patterns.

#Last-Minute Tips

• Time Management: Don't spend too long on a single question. Move on and come back if you have time.
• Common Pitfalls: Avoid oversimplifying the models. Remember that real cities are complex and often exhibit characteristics of multiple models.
• Strategies: Always relate the models to real-world examples. This will help you make connections and remember the key features.
