The problem faced by this empirical study is to investigate the relationships between intra-urban migration and spatial urban structure. Using canonical correlation analysis, the main features of the relationships are identified and a measure of the redundancy between the two sets of variables is provided. The unsolved aggregation problem is also discussed. All results indicate a significant though rather weak linkage between migration and urban structure. Comparison of results at the inter-sector and intercommune scales points to the existence of stronger relationships at the larger, inter-commune scale.
