Immigrant minority groups and immigrant minority languages in Europe are viewed from three perspectives (demographic, sociolinguistic, and educational) through case studies. The first part, using a demographic approach, includes research on immigrant minority groups in population statistics of both European Union and English-dominant countries (Australia, Canada, United States, South Africa) with substantial immigrant populations. The second part, using a sociolinguistic approach, examines the vitality of immigrant minority languages. Research methods are first explained, and case studies are presented for Turkish, Arabic, Berber, Papiamentu, English, Sranan/Surinamese, Chinese, Malay, Spanish, Hindi, and Romansh. The third part looks at case studies on the status of minority languages in education in European Union countries (Belgium, France, Germany, Great Britain, Netherlands, and Sweden). Appended materials include a home language survey questionnaire and instructions, a questionnaire on immigrant minority language instruction in compulsory education, and the text of a directive of the Council of the European Communities on the schooling of children of migrant workers.
