Home to immigrants from more than 140 countries speaking over 180 languages, Los Angeles is a microcosm of the world. While Los Angeles' ethnic enclaves have been the subject of study by researchers from a wide range of fields, these enclaves remain under-researched from a linguistic standpoint. Multilingual La La Land addresses the sociolinguistic landscape of the Greater Los Angeles (GLA) area, providing in-depth accounts of the sixteen most spoken languages other than English in the region. Each chapter introduces the history of the language in the L.A. region, uses census figures and residential densities to examine location-based and network-based speech communities, and discusses the patterns of usage that characterize the language, including motivations to maintain the language. How these patterns and trends bear on the vitality of each language is a central consideration of this book.
