In the period 1950* 2020, international migration in Europe changed significantly. One of the most char-- acteristic features was the change in net migration from negative to positive. At the beginning of the twenty first century, Poland belonged to the minority of countrie s in this respect that is, it experienced strong emigration but only minor immigration. However, migration in Poland has also been changing. In the second decade of this century, the outflow of people has weakened, the inflow of migrants has increased an d the migration balance has become positive. I analyse these phenomena from the theoretical perspective of the migration transition that was experienced in the second half of the twentieth century by most countries in Western, Northern and Southern Europe. I attempt to answer the question of whether the latest migration phenomena prove that this transition is also occurring in Poland. In conclusion, I argue that the available toKeywords: migra date evidence provides an affirmative answer to this question.

In this paper we review the significant political events and economic forces shaping contemporary mi-gration within and into Europe. Various data sources are deployed to chronicle five phases of migration affecting the continent over the period 1945–2015: immediate postwar migrations of resettlement, the mass migration of ‘guestworkers’, the phase of economic restructuring and family reunion, asylum-seek-ing and irregular migration, and the more diverse dynamics unfolding in an enlarged European Union post-2004, not forgetting the spatially variable impact of the 2008 economic crisis. In recent years, in a scenario of rising migration globally, there has been an increase in intra-European migration com-pared to immigration from outside the continent. However, this may prove to be temporary given the convergence of economic indicators between ‘East’ and ‘West’ within the EU and the European Eco-nomic Area, and that ongoing population pressures from the global South, especially Africa, may inten-sify. Managing these pressures will be a major challenge from the perspective of a demographically shrinking Europe.
