In AP Human Geography, this principle specializes in:
- Market areas
- Threshold
- Range
- Hierarchy of settlements
Who Developed Central Place Theory?
| Detail | Information |
|---|---|
| Theorist | Walter Christaller |
| Year | 1933 |

|---|---|---|
| High Order | Large city | Specialized services |
| Medium Order | Town | Common services |
| Low Order | Village | Basic services |

- Short range
- Low threshold
Examples: milk, bread, newspapers
High-Order Goods
- Bought now and again
- Expensive
- Long range
- High threshold
Examples: vehicles, rings, universities
This difference is crucial for AP Human Geography checks.
Central Place Theory Models (K-Values Explained)
Christaller proposed three fashions, known as K-values, which describe how central locations are arranged.
K-Value Models Table
| Model | K-Value | Purpose |
|---|---|---|
| Marketing Principle | K = 3 | Maximize consumer access |
| Transportation Principle | K = 4 | Efficient transportation |
| Administrative Principle | K = 7 | Political control |
Most Important for AP Exam
👉 K = 3 (Marketing Principle) is the most tested in central area theory AP human geography.

|---|---|
| Unrealistic assumptions | World is not flat |
| Technology ignored | E-commerce changes range |
| Cultural factors missing | Preferences vary |

Central Place Theory vs Real World
| Theory | Reality |
|---|---|
| Even spacing | Uneven growth |
