This book focuses on the increase of urban multilingualism in Europe as a consequence of processes of migration and minorisation. It offers multidisciplinary, crossnational and crosslinguistic perspectives on immigrant minority languages at home and in school in six major multicultural cities across Europe. From North to South these cities are Gцteborg (Sweden), Hamburg (Germany), The Hague (The Netherlands), Brussels (Belgium), Lyon (France) and Madrid (Spain). In each of these cities, with the exception of bilingual Brussels, either a Germanic or a Romance state language has a dominant status in public life. This book is the outcome of the Multilingual CitiesProject, a study based on large-scale empirical findings and carried out under the auspices of the European Cultural Foundation.
