Neighbourhood change in suburban and ex-urban areas in the Paris metropolitan region: Property-level data and the neighbourhood problem(s) (1996-2012)



On suburban fringes, the spatial and social structuring of neighbourhoods yields fragmented and reticular morphological patterns. Based on a case study in the greater Paris metropolitan areas, this paper proposal highlights the outcomes of planned subdivisions as a major type of morphology on the metropolitan fringe. But spatial fragmentation and reticular relations both challenge classical methods of urban analysis. An investigation of neighbourhoods in post-suburbia requires a better theoretical understanding of the relationships between subdivisions and the various contexts that define a multi-level vicinity, with intricate effects produced by several geographical level in which the subdivisions are embedded: the neighbourhood, the community, the local jurisdiction, etc.


To avoid the “constant size neighbourhood trap” (due to the size and the relative fuzziness of their boundaries), the paper proposes methods to construct and analyze price change and social change, considering ad-hoc small areas, smaller than the municipal boundaries, which is the most commonly used. Using smoothing techniques and multivariate analysis, the paper presents a spatial analysis of property-level data from the Paris Chamber of Notaries (1996-2012) in a GIS, comparing several spatial definitions of small areas to better render the level of social homogeneity constructed by subdivisions and planned communities. By the means of a multivariate analysis, local trajectories of social and occupational status of seller and buyer pairs in properties located in subdivisions and planned developments are matched with data on geographical mobility of buyers and prices, and compared between 1996 and 2012.



Professor Renaud Le Goix, Université Paris 1 - Panthéon-Sorbonne



Renaud Le Goix is a geographer, professor at the University Paris Diderot, membre of Geographie-cités research lab. He has been an Associate Professor (Maître de conférences) since 2004 at the University Paris 1 Panthéon-Sorbonne. He holds an accreditation to supervise research (HDR, 12/2013). He has expertise in urban geography, spatial analysis, modeling and mapping of social differentiation patterns, GIS. His research mainly focuses on suburbanism, in France and in the US, analyzing the contextual patterns of suburban built environment (subdivisions) in terms of property values, segregation patterns, and the relationships between the private residential governance and the local government bodies. He has expertise spatial analysis of social facts, modeling and mapping of social differentiation patterns. His doctorate thesis (2003) on privatization of residential estates and gated communities in the United States, aimed at demonstrating the impact of residential enclaves on segregation patterns, using spatial analysis tools and GIS. He has been an Alliance visiting professor at Columbia University (Spring 2013), and was awarded several research grants (US. NIH 2009 ; France ANR 2007), has been a Fulbright fellow (2002) and Tocqueville Fellow (2000). He has been appointed vice-president for Research of University of Paris 1 (2009-2012), and has been in charge for the University of the p reparation for the Excellence Clusters successful answers to the IDEX and LABEX CFPs (
