Urbanization and Urban Concepts
Factors Influencing Urbanization
- Transportation
- Innovations in transportation significantly affect city layouts and sizes over time.
- Communication
- Advances in communication systems enable business growth, which fuels city expansion.
- Rural to Urban Migration
- Movement of people (often farmers) from rural areas to urban centers in search of employment.
- Redevelopment
- Activities aimed at revitalizing areas suffering economic decline.
Cities Across the World
- Learning Target: Explain urbanization and suburbanization processes.
- Megacities
- Cities with populations of 10 million or more, e.g., Cairo, Mumbai, Beijing, Dhaka, Osaka-Kobe-Kyoto.
- Metacities
- Cities with populations of 20 million or more, e.g., Tokyo, Delhi, Shanghai, São Paulo, Mexico City.
- Micropolitan Areas
- Populations between 10,000 - 50,000, consisting of a smaller city and its surrounding towns/counties.
- Megalopolis
- A region where multiple large cities and areas grow together.
- Metropolitan Statistical Area
- Comprises a central city of at least 50,000 and linked urban areas.
- Suburbanization
- Population shift from urban centers to suburbs, leading to urban sprawl.
- Sprawl (Urban Sprawl)
- Unchecked outward growth of urban areas.
- Edge Cities
- Economic activity hubs on the periphery of large cities.
- Exurbs
- Prosperous districts outside the suburbs, often near natural attractions.
- Boomburbs
- Rapidly growing incorporated communities of over 100,000 residents, not the largest in the region.
Cities and Globalization
- Learning Target: Explain how cities represent globalization processes.
- World City (Global City)
- Centers of the global economy making major decisions about commercial networks and financial markets (e.g., Tokyo, NY, Paris).
- Urban Hierarchy
- Ranks urban settlements by population size and economic function.
| Type of City | Characteristics | Examples |
|---|---|---|
| World City | Dominant in economic standing | New York, London, Tokyo |
| Megalopolis | Extended conurban area | BosNYwash (Boston-NY-Washington DC) |
| Alpha City | Primary regional node in the global economy | New York, London, Hong Kong, Sydney |
| Beta City | Secondary regional node in the global economy | Washington DC, Dallas, Berlin, Wuhan |
| Gamma City | Tertiary regional node in the global economy | Cleveland, St. Petersburg, Austin, St. Louis |
- Global Connections
- Cities are connected globally through various networks:
- Transportation Services
- Activities facilitating travel for services and daily life.
- Communication Systems
- Advanced systems that facilitate immediate information access.
- Business Services
- Links to corporate headquarters of international companies.
The Size and Distribution of Cities
Learning Target: Identify urban concepts that explain city distribution and interaction.
Rank-Size Rule
- The nth-largest settlement has 1/n the population of the largest settlement (e.g., U.S. cities).
Primate City
- An urban area dominating a country’s economy, culture, and politics, more than twice the population of the next city (e.g., London, Paris, Bangkok).
- Pros: Attracts international trade and business.
- Cons: Centralization of services.
Christaller's Central Place Theory
- Explains service distribution and settlement patterns.
- Key Concepts:
- Central Place
- Settlement providing certain products/services.
- Threshold
- Minimum population needed to support a business.
- Range
- Distance people travel to acquire a good.

- Visual representation of settlement types (City, Town, Market Town, Village) and their boundaries.
