This book explores individual language policy among bilingual youth who belong to different ethnic minority groups in Vietnam, through vivid stories detailing their life with multiple languages. It examines the youth's daily language behaviours through the unique theoretical lens of individual language policy, and the ways in which this policy interacts with and is influenced by language policies at macro, meso and micro level. It contributes to research on language and identity, and language policy in non-Anglophone societies and will appeal to a broad international readership, including researchers in sociolinguistics, teachers working with ethnic minority students and policymakers concerned with minority language maintenance around the world.
