The electoral and political consequences of suburbanisation recently regained interest in the Anglo-Saxon literature, pointing to a growing polarisation between city and suburban fringe. This paper analyses these processes in the Antwerp urban region and shows the development of a similar electoral divide that is supported by the political parties involved. These observations add to the existing evidence that city–suburban polarisation in Belgium cannot be simply equated with the Anglo-Saxon experience, where a complete suburban fencing off from the city is observable. Rather, because of the comparatively limited development of functions in the Belgian suburbs, a suburban discourse emerges that focuses on safe and accessible cities for the suburban user, yet without much reference to its present inhabitants.
