Urbanization & City Models - Complete Interactive Lesson
Part 1: Core Concepts
🌍 Urbanization
Part 1 of 7 — The Growth of Cities
What Is Urbanization?
Urbanization is the increasing percentage of a population living in urban areas. Two distinct measures:
| Measure | Definition | Example |
|---|---|---|
| Urbanization rate | % of population living in cities | US: ~83%; India: ~35% |
| Urban growth rate | Speed at which urban population increases | Lagos: ~3.5% per year |
🔑 A country can have high urbanization (high % urban) but low urban growth (slow increase) — like the US. Or low urbanization but high urban growth — like sub-Saharan Africa.
Models of Urban Structure
| Model | Creator | Key Idea |
|---|---|---|
| Concentric Zone | Burgess (1925) | City grows outward in rings from CBD |
| Sector Model | Hoyt (1939) | Zones extend as wedges along transportation routes |
| Multiple Nuclei | Harris & Ullman (1945) | City has several centers of activity, not just one CBD |
| Galactic City | Harris (1990s) | Edge cities and suburbs surround a declining CBD |
| Latin American City | Griffin-Ford | CBD + spine of wealth; disamenity zones on outskirts |
| African City | De Blij | Three CBDs: colonial, traditional market, periodic market |
| Southeast Asian City | McGee | Port zone + CBD; no single dominant center |
The AP exam frequently asks you to compare these models and apply them to real cities.

Key Urban Concepts
| Term | Definition |
|---|---|
| CBD | Central Business District — commercial/financial core |
| Suburbanization | Movement from city centers to suburbs (common in developed countries) |
| Counterurbanization | Movement from urban to rural areas |
| Gentrification | Wealthier residents moving into lower-income neighborhoods, raising property values |
| Edge city | Suburban area with its own employment, shopping, and entertainment |
| Megacity | Urban area with 10+ million people (Tokyo, Delhi, Shanghai) |
| Primate city | Largest city dominates country disproportionately (Paris, London, Bangkok) |
| Rank-size rule | nth largest city has 1/n the population of the largest city |
Primate City vs. Rank-Size Rule
- Primate city pattern: One city is 2-3x larger than the 2nd city (Bangkok, Paris)
- Rank-size pattern: Smooth distribution — city sizes follow a predictable hierarchy
- Most developing countries have primate cities; developed countries more often follow rank-size
Applied Recall ✍️
-
An urban area with 10 million or more people is called a _______.
-
When wealthier residents move into lower-income neighborhoods, raising property values, this is called _______.
-
The model where the largest city is 2-3x bigger than the second-largest is the _______ city pattern.

Causes of Urbanization Worldwide
In Developing Countries (rapid urbanization)
- Rural-to-urban migration — push: lack of rural jobs; pull: perceived urban opportunities
- Natural increase — young age structure in cities leads to high birth rates
- Reclassification — previously rural areas become classified as urban as they grow
In Developed Countries (slow/stalled urbanization)
- Suburbanization dominates — people leave central cities for suburbs
- Counterurbanization — some move to rural areas (remote work enabling this trend)
- Gentrification — select inner-city neighborhoods see population growth
⚠️ AP Exam Tip: Be prepared to analyze the CAUSES of urbanization in a specific region. The factors driving urbanization in Lagos, Nigeria differ significantly from those in London or Tokyo.
