National census data contain information on place of residence and place of work. It is possible to combine this information and create journey-to-work ows. The process of establishing these ows are presented in this paper. The intramax method is explained and used to identify functional regions based upon these ows. Interesting applications, such as the demarcation of regions in South Africa are considered and solutions to disputed areas are put forward. The process of the creation of the current provincial boundaries are discussed. New boundaries, based on the intramax analysis of the journey-to-work data are proposed for four or ve new provinces. Results compare favourably with those from a principal component and cluster analysis, which has previously been used to demarcate the South African space economy into a hierarchy of development regions.
