Europe is a favoured destination for many migrants. The region's economic prosperity, relatively high level of political stability and democratic principles are appealing to many migrants, whether they be asylum-seekers or regular migrants in search of work or looking to study.In this book we examine views on integration in 17 European countries, and explore how these are translated into national policy and what efforts are being made in the various countries to map out the integration processes of migrants and track them over time.The different chapters in this book present a kaleidoscopic overview of opinions about integration and the efforts to make integration measurable in practice. Europe has spent more than ten years trying to achieve greater uniformity in integration policy across the Member States. However, from this book we learn that we have to accept that harmonisation in the monitoring of immigrant integration in Europe is still some way off.
