||The paper examines migration from ten countries that will join the European Union in 2004 to the current EU member states. Introductory chapters are devoted to the theoretical approaches, short summary of current empirical findings and to historical background. Section describing the migration patterns within the European Union illustrates great importance of non-economic factors when speaking about mobility of people.
