This document discusses land use patterns in urban areas using models of urban land use zones. It summarizes the Burgess and Hoyt models which divide cities into concentric zones and sectors based on land value and use: The Central Business District (CBD) contains commercial areas, offices, and high density buildings. The inner city surrounds the CBD and contains high density housing and former factories. The suburbs contain lower density housing from the interwar period with gardens and facilities. The rural-urban fringe is on the edge of the city with a mixture of housing, farms, and recreational areas.
