Abstract
This paper examines the validity of J.S. Adams' model on intra-urban migration in the context of the elderly migration in Ichikawa City. Each distance and direction between addresses of origin, destination and the nearest Central Business District (CBD) was measured by Geographic Information System (GIS). Questionnaires on migration were also sent out to the migrants. The finding is that distance bias, directional bias and sectoral bias exist in the migration significantly. However, long movement distances are influenced by the location of nursing homes or their children addresses rather than CBD. Short movement distances are influenced by reconstruction of rental housing. There are a small number of movements of their own will which have effects on these biases.
