International migration is one of the prominent facts in the contemporary world, which affects the political, socio-economic and cultural processes both in origin and destination countries. Historically, Western Europe has been one of the most attractive destinations for migrants because of the level of socio-economic development and political stability. However, there are many complex institutional, socio-economic and cultural issues to be addressed to achieve the integration of migrants and to eliminate social inequalities between the native populations and migrants in these host countries. In this respect, this book examines some aspects of socio-economic disparities between native populations and the migrants in Belgium, Germany, France, the Netherlands, Sweden and the United Kingdom. Different migration histories, labour market features and welfare state characteristics of these countries are expected to provide insight about how the integration-related and inequality-related issues emerge in diverse social and institutional settings. The study covers the empirical analyses of the disparities in the labour market and accessing the social benefits between 2004 and 2016 by using comparable cross- country survey data. These analyses attempt to demonstrate the relationships between these two domains. The study has a comparative approach, which aims at providing comparable evidence both across the countries and over time in each of the selected countries.
