The theoretical framework illustrating urban spatial structure in many Latin American cities features a central business district (CBD) as its focal point. Radiating outwards from this core are zones characterized by varying levels of wealth and residential quality. A prominent feature is the “spine,” an extension of the CBD often containing elite residential areas, commercial establishments, and amenities. Disamenity zones, often peripheral squatter settlements, mark the outer reaches, reflecting significant socio-economic disparities within the urban landscape. These zones stand in stark contrast to the inner rings of affluence and stability.
This model is valuable for understanding the historical impacts of colonialism and globalization on urban development in the region. It highlights the socio-economic stratification inherent in many Latin American cities, showcasing spatial inequalities in access to resources and opportunities. Studying its components allows geographers to analyze patterns of migration, urbanization, and economic activity and understand how urban policies have shaped contemporary urban landscapes. The model serves as a baseline for comparative analysis, informing studies of urban development in other regions grappling with similar challenges.
