The sector model theory is a concept in urban geography that proposes cities develop in sectors or pie-shaped wedges radiating outwards from the central business district (CBD). Each sector represents a different type of land use, such as residential, industrial, or commercial.
The Sector Model influences urban planning by shaping transportation routes and land use patterns. It affects property values and guides infrastructural development, often directing economic investments and determining the social landscape of urban areas.
