Sign language vitality through the lens of a pioneering interactive Atlas: a first look at the sociolinguistic profile data collected by the Sign Hub project

Abstract To investigate the under-researched topic of sign language vitality, the authors evaluate a set of sociolinguistic data gathered as part of the Sign Hub project. The subproject Atlas aimed to create an interactive online tool for researchers, teachers, and interpreters to compare sign languages’ sociolinguistic, grammatical, lexical, and phonological features. This paper presents an analysis of ten sign languages, i.e. the first batch of socio-historical data submitted to the subproject. The authors find that nearly all of them have been subjected to oppression, and their documentation is limited. Their vitality is supported by good awareness among the hearing community and use within educational institutions, national deaf associations and local deaf clubs. Vitality is threatened by low provision of sign language media and a lack of interpreter training. The paper concludes that the Atlas has considerable utility in research on sign language vitality, which may be augmented by adding further diachronic components.
