title: Migration in Finland, a multi-level system of regions.
abstract: A systems approach is applied to the study of migration trends in Finland for the period 1971-1981, with particular attention to the period 1971-1978.  The results indicate the existence of six permanent migration regions linked by a multilevel system.  "The organization of this system varies from one part of the country to another, the most common modes being hierarchical tree flow networks belonging to a nodal system and polar and dendritic networks associated with a highly polarized system.  The nodal system mode is seen to be increasing in currency."
