Abstract

The commencement of the 21st century was marked by a greater intensity of depopulation processes in Poland. From the demographic perspective, a decline in the population number is an outcome of the interaction of two factors: a negative natural increase and a negative balance of migration that may work separately or in tandem. When the level of the natural increase falls, migration, especially its balance, gains importance as a factor influencing the population size. In the early 21st century, population flows played a significant role in the growth of the populations in Warsaw, Krakow, and Wroclaw, whereas Poznań and Łódź saw an accelerated population loss. The purpose of the study was to assess the direct impact of migra- tion on the growth of populations in big Polish cities, as well as its indirect impact revealing itself through increased birth rates from migrants. The analysis spans the years 2002-2017 and uses data from publica- tions of the Central Statistical Office (Demographic Yearbooks) and from the Demografia database (http:// demografia.stat.gov.pl/bazademografia/).
