In Belgium, studies on divorce with a demographic approach are rare and those on its spatial dimension, especially in relation to internal migration, are almost non-existent. The objective of this article is to try to fill this gap, at least partially, by analysing the evolution of the spatial distribution of divorced people in Belgium since 1970 on the one hand, and the characteristics of the migration of newly divorced people on the other hand, while linking the two phenomena. This research is based on the exploitation of exhaustive data from the 1970 and 1981 population censuses and the DEMOBEL database constructed by Statbel (Statistics Belgium). The latter includes demographic information from the Belgian National Register for the period 1991-2017 coupled with data from the 1991, 2001 and 2011 population censuses.The mapping of the divorced in Belgium and its evolution since 1970 has highlighted a phenomenon of spatial diffusion, marked in the first part of the process by cultural and secularisation geography, and by a diffusion within the urban hierarchy. This geography of the divorced may also be shaped by their migration. Nevertheless, the results of the analyses highlight a strong local anchoring of the newly divorced, who most often remain in their local environment following the divorce. Moreover, the municipalities that receive the most newly divorced migrants also tend to be the municipalities where the divorced are over-represented, thus confirming that the migration of newly divorced people tends to reinforce existing spatial structures.
