Urban riots, such as in France in 2005, have drawn attention on the spatial determinants of social discontent. We provide evidence on the pervasive collective perception of a dramatic increase of the well-being disparities within the Paris Region during the decade preceding the 2005 riots. We ground our well-being indicator on a spatialized version of Sen's normative capabilist approach, which allows to explicitly take into account the impact of one's localization on one's realizations, opportunities and freedom. Then, using multidimensional poverty indicators and ESDA, we show a global improvement of the Paris region municipalities' Capabilist Spatialized well-being (CaS) between 1999 and 2006 as well as a catching-up phenomenon between advantaged and disadvantaged municipalities. Nevertheless, we also find a growing cluster of very disadvantaged municipalities, some of which have witnessed a decrease of their CaS level. This evidence may explain the belief of a growing socio-spatial fracture within the Paris region.
