Determinants of Interregional Migration Flows in Korea by Age Groups, 1995-2014

چکیده
Despite the growing importance of interregional migration at the local level in rapidly aging society, past literature overlooked the relationship between these two demographic phenomena. To better understand the determinants of interregional migration and its implications for population aging, this study estimated fixed-effects models derived from the gravity model of migration using population registration data. Contrary to theoretical expectation, economic determinants of migration showed similar patterns across three age groups. Other than the effect of crude marriage rate for young age group, life course variables showed inconsistent effects on migration. Trends in migration flows by geographical regions indicated that some provinces are in double jeopardy because their elderly population is increasing while the young population decreases. Visual inspection of migration systems drawn from social network analysis suggested that migration streams between Seoul and Gyeonggi overwhelms all other regions and that Ulsan and Jeju are isolated throughout the periods.

Interregional Migration in Spain: a Semiparametric Analysis
This paper analyses the determinants of internal migration in Spain between 1995 and 2002. After a brief descriptive study, we begin by presenting an analytical model of internal migration flows. Subsequently, we carry out a semiparametric analysis of some of the main factors affecting the size of net migration rates. The general conclusion that we come to is that these rates are mainly influen...
متن کاملMigration Processes Modeling with Cellular Automation
The problem of interregional migration flows modeling is being studied. The conjecture that modeling household migration behavior at local level in view of community interactions and using cellular automata results in adequate forecasting of interregional migration flows has been numerically confirmed. A computer program was developed in order to implement the cellular automaton suggested in th...
متن کاملMigration and Regional Unemployment in Italy
Does interregional migration equilibrate regional labor market performances? We answer this question focusing on regional unemployment dynamics in Italy over the 1995-2006 period, when a strong flow of out-migration from the South to the North occurred. Using System-GMM estimators for spatial dynamic panel data models in the presence of endogenous variables, the empirical analysis documents tha...
متن کاملEconomic and Spatial Determinants of Interregional Migration in Kazakhstan
Economic and Spatial Determinants of Interregional Migration in Kazakhstan In this paper we analyze economic and spatial determinants of interregional migration in Kazakhstan using quarterly panel data on region to region migration in 2008-2010. In line with traditional economic theory we find that migration is determined by economic factors, first of all income: People are more likely to leave...
متن کاملInterregional Migration in Germany: Characteristics and Effects for Regions and Migrants
German unification and the subsequent breakdown of economic activity in East Germany initiated enormous migration flows from East to West Germany. People from East Germany moved towards West Germany, where wages are higher and employment opportunities are more favourable. Our paper takes a somewhat broader perspective; it analyses migration flows between four macro regions, i.e. East, North, So...
