A first synthesis of work done in sociolinguistic superdiversity, this volume offers a substantial introduction to the field and the issues and state-of-the-art research papers organized around three themes: Sketching the paradigm, Sociolinguistic complexity, Policing complexity. The focus is to show how complexity rather than plurality can serve as a lens through which an equally vast range of topics, sites, and issues can be tied together.

Superdiversity captures the acceleration and intensification of processes of social 'mixing' and 'fragmentation' since the early 1990s, as an outcome of two different but related processes: new post-Cold War migration flows, and the advent and spread of the Internet and mobile technologies. The confluence of these forces have created entirely new sociolinguistic environments, leading to research in the past decade that has brought a mixture of new empirical terrain-extreme diversity in language and literacy resources, complex repertoires and practices of participants in interaction-and conceptual challenges.

Language and Superdiversity is a landmark volume bringing together the work of the scholars and researchers who spearhead the development of the sociolinguistics of superdiversity.
