Przestrzenny zasięg migracji a wiek migrantów na przykładzie największych miast w Polsce
Geographical extent of migration and the age of migrants on the example of the largest cities in Poland

Summary/Abstract: The article is about the migration of people to and from large cities. The aim of the study is to determine the influence of physical distance on the geographical extent of internal migrations depending on the migrants’ age. Five major cities in Poland were analysed in this context. Gravity models, which describe migrations as a function of geographical distance, were applied in the study. The statistics on the number of internal migrations relating to 2018 used in the analysis came from Statistics Poland (and more specifically, from current population registers).The analysis allowed the determination of the exponents of the gravity function and their variability depending on the age of migrants. The results demonstrate that in the case of the most mobile people (aged 25–29), the extent of migration fields (inflow and outflow) is characterised by the greatest geographical spread. Migration inflow models indicate that among the oldest people (aged 85 and above) longer-distance relocations are more likely than short-distance moves. The least mobile groups comprise people aged 35–39 and those recently retired (aged65–69).
