Using the data from the residential registration system we investigate the patterns of interregional migration in South Korea during the period of 1990-2000. The network analysis techniques are applied to the annual migration streams among fifteen ggeographic units, i.e., nine provinces and six large metropolitan areas. This study provides such network measures as density and degree centrality of migration streams for each year to determine the nature of changes over time in the structure of interregional migration. We also examine the demographic, economic, and political correlates of the changing structures of interregional migration in South Korea.
