Theories of Urban Development

Theories of urban development explain how cities grow and change. Key theories include: 1. **Concentric Zone Model**: Cities expand outward in rings from a central point. 2. **Sector Model**: Development occurs in sectors or wedges, often along transportation routes. 3. **Multiple Nuclei Model**: Cities form around multiple centers rather than one core. 4. **Urban Realms Model**: Cities evolve into interconnected regions with semi-independent suburban areas. These theories help us understand patterns of population, economy, and land use, offering insights into urban planning and growth trends.
