The introductory chapter discusses key theoretical concepts upon which the book develops, such as the meaning of integration and inclusion, broadly understood but also with reference to the labour market and to the wider social context. Hence it reflects on how different labour outcomes affect empowerment and participation as key aspects of newcomers’ integration. It also introduces the reader to the multilevel (local–national–European) and multidimensional (micro–meso–macro) framework of the study underpinning the book, as well as to its large quantitative and qualitative empirical basis. The introduction also discusses ethical aspects which pertain to research with vulnerable individuals. Finally, the layout of the book is presented and explained.
