Zmiany w zatrudnieniu mieszkańców województwa opolskiego po akcesji Polski do Unii Europejskiej w świetle badań empirycznych

The paper presents the quantitative changes that have occurred in employment among the rural population of Opole Voivodship after Polish accession to the European Union - over the years 2006-2010. Determination of these changes was possible because in 2006 and in 2010 there had been conducted quantitative research on the same sample group and with usage of the same research method. The comparative analysis of results of the research proved that within four years both the number of people working permanently in Poland and working abroad have changed. The results also indicated significant differences in the trends of changes between the two groups of the population living in Opole Voivodship - among the autochthon population who have the Polish and German citizenship and among non-autochthonous population who have only Polish citizenship.
