How do individuals experience multilingualism and mobility in the context of Europeanization and globalisation? The contributors explore language-in-education policies and family language policies, as well as the complex interface between multilingualism and space. They provide fresh insights on key issues in sociolinguistics, multilingualism and language policy via discussion of rich qualitative data. The multiple sites analysed in the chapters are located in France, Germany, Luxembourg, Hungary and Moldova. Some of the chapters dealing with France, including one about the overseas French territory of La Reunion, are written in French.
