A circulation model of interprovincial migration in Finland

Abstract

The study deals with the interprovincial migration in Finland between the years 1963 and 1966. Attention is particularly concentrated upon the relation­ship between migration probability and distance. The relationship has been analyzed by means of the linear correlation coefficient and the distance exponent of the Pareto formula. As a rule, the more migration probabilities depend on distance, the steeper is the migration‑probability gradient and the smaller are the migration probabilities. This conclusion has been presented as a circulation model. Two parts may be distinguished in the model: 1) The upward migration probabilities in the hierarchical scale (or the greatest migration probabilities) constitute the ‘irregular’ portion of the model. The migration probabilities are not regularly correlated to distance. 2) The downward migration probabilities in the hierarchy decrease in a ‘regular’ manner with increasing distance.
