ABSTRACT
The dichotomy of moving/staying is a common point of departure in geographical migration research. Since the late nineteenth century, when Ernest George Ravenstein formulated the 'laws of migration', influential theories of migration have regarded regional economic disparities as major determinants of migration. In relation to international migration the alternatives include a variety of time-space strategies such as remaining at the place of origin, temporary circulation, rural-rural migration and long-distance migration to towns and cities. Migration is just one form of time-space mobility, while others include for instance staying and commuting. The studies of time-space trajectories, biographies and life paths, initially introduced by T. Hagerstrand, have received increasing attention in geographical migration studies. The push-pull model presents a static view of migration determinants, although it is obvious that the determining factors are changing over time. Sometimes, however, migration ceases due to more restrictive immigration policy, unsuccessful adjustment and changing subsistence opportunities.
