The aim of the article is both to measure and assess the degree of correlation between the migration size and geographical distance. The subject of the research is migration inflow and outflow in the years 1990—2015 in Śląskie voivodship. The Pareto function was used to assess the influence of distance on migration. The obtained results indicate decreased attractiveness of Śląskie voivodship. Starting from the end of the 1990s the outflow of the local population increased, and thus the influence of distance on the decision to leave this voivodship decreased. The inhabitants more and more frequently decided to migrate to distant regions of Poland.

Celem opracowania jest pomiar i ocena stopnia zależności pomiędzy odległością geograficzną i poziomem rozwoju społeczno-gospodarczego a wielkością migracji. Obiektem badania jest województwo śląskie, zaś przedmiotem badania – napływ i odpływ migracyjny ludności w latach 1990-2015. W ekonometrycznej analizie ruchów migracyjnych wykorzystano modele potęgowe typu funkcji Pareto. Uzyskane wyniki wskazują, że zarówno odległość geograficzna, jak i zróżnicowanie przestrzenne poziomu rozwoju społeczno- gospodarczego poszczególnych województw Polski mają istotny wpływ na przemieszczenia ludności województwa śląskiego. Co więcej, w miarę upływu czasu odległość geograficzna jako determinanta, która wpływa destymulująco na ruchy migracyjne, straciła nieco na znaczeniu.

The goal of the paper is to measure and assess the degree of relationship between geographical distance and the level of socio-economic development towards the size of migration. Silesian Voivodeship is the object of the research, and migration inflow and outflow of the population between 1990 and 2015 is its subject. Power models of the Pareto function type were applied in the econometric analysis of migration movements. Obtained results show that both geographic distance and spatial diversification of the level of socio-economic development in individual voivodships in Poland have a significant impact on the movements of the population of Silesian Voivodeship. Furthermore, geographic distance as a determinant that has a destimulating influence on migration movements has slightly lost its significance over time.
