Urban Sociolinguistics is a sociolinguistic study of twelve urban settings around the world. Building on William Labov's famous New York Study, the authors demonstrate how language use in these areas is changing based on belief systems, behavioural norms and linguistic practices. Providing new perspectives on crucial themes such as language choice and language contact, language and identity, language policy and social networks, this is key reading for students and researchers in the areas of multilingualism and super-diversity within sociolinguistics, applied linguistics and urban studies.
