Beyond the metropolis. The spatial diffusion of the residence of middle- and high-income social groups in Bogotá

Abstract Changes in social composition across the world affect the form of appropriation of the territory. Unlike other conventional approaches to the analysis of urban growth and cities’ hierarchies, part of the physical and population growth manifests itself in areas relatively distant from the metropolitan influence area, involving middle- and high-income families differentiated by their productive life cycle. The aim of this paper is to analyze the impact, on physical and population growth, of the structural migrations – changes of principal household – of Bogotá residents. Spatial diffusion in the post-metropolitan area confirms the development of urban conventions and repeats patterns of socio-spatial segregation with an impact on the segmentation of the real estate market of the municipalities observed in the study.

摘要：全球社会构成的变化影响着地域空间的占有形式。与其他分析城市增长与城市层级体系的传统研究路径不同，城市实体空间扩张与人口增长的部分表现出现在距离都市区影响范围相对较远的区域，涉及以生产生命周期划分的中高收入家庭。本文旨在分析波哥大居民的结构性迁移——即户主变更——对城市实体空间扩张与人口增长的影响。后都市区的空间扩散现象印证了城市发展范式的演进，并重现了社会空间分异的格局，进而对本次研究涉及的各自治市的房地产市场细分产生了影响。
