Real-World Examples of the Sector Model: Case Studies of US Cities

📚 Quick Study Guide

• 🌍 The Sector Model, developed by economist Homer Hoyt in 1939, explains urban growth as a series of sectors radiating out from the Central Business District (CBD).
• 🏘️ Unlike the concentric zone model, the sector model considers transportation routes and major lines of movement.
• 🏭 Industrial sectors often follow railway lines or rivers.
• 💰 Higher-income residential areas tend to grow outwards, away from industrial zones.
• 📉 Lower-income areas often lie adjacent to industrial and transportation corridors.
• 📈 The model highlights uneven distribution of social groups and activities within a city.
• 📍 Key assumption: Cities grow in wedge-shaped sectors rather than rings.
