City growth models

City growth models are theoretical frameworks used to understand how urban areas expand and develop over time. They explain patterns of population distribution, land use, and economic activity within cities. Common models include the Concentric Zone Model, which suggests that cities grow outward in rings from a central point, and the Sector Model, which indicates that growth occurs in wedges or sectors. Other models, like the Multiple Nuclei Model, propose that cities have multiple centers of activity rather than a single downtown. These models help planners and researchers analyze urban dynamics and inform development strategies.
