This paper focuses on the relative spatial distribution of the French-speaking and English-speaking population in the greater Moncton area. Using data from the Statistics Canada censuses of 1981, 1991 and 2006 at the level of dissemination areas, we describe the transformation of the socio-spatial structure of Moncton. We have focused on the changes in the location of the French-speaking population. Our social spatial analysis was done by means of geographic information systems (GIS).
