Social and housing tenure mix in Paris intra-muros, 1990-2010

This paper sheds light on the relationship between the social and tenure mix in Paris between 1990 and 2010. Using two quantitative methods (cluster analysis and entropy indices) it explores the relationship between the social and tenure mix at the microscale. Although no statistical correlation was found, other relationships were discovered. First, the social mix is a function of the general characteristics of the neighbourhood or district. Second, social upgrading and homogenization began in the 1990s, and the ideal' social mix was a temporary phase before upper socio-professional groups became overrepresented. The growing availability and diversification of social housing has neither created a greater social mix nor slowed down social upgrading, either in general or for social housing in particular. Finally, the fact that there are different categories of social housing landlords nuances the outcomes of policies.
