Abstract

This article explores factors affecting the endangerment levels of sign languages, and how these levels were assessed through an international collaboration using a systematic scoring scheme. This included adapting UNESCO’s Linguistic Vitality and Diversity survey and developing a system for determining endangerment levels based on the responses. The survey needed to be carefully revised because even though many spoken language procedures can be also used for sign languages, there are additional challenges and characteristics that uniquely affect sign language communities. In this paper, we present vitality scores for 15 languages, including both national and village sign languages, and the major factors threatening their vitality. The methodology of scoring based on averages is innovative, as is the workflow between the questionnaire respondents and scoring committee. Such methodological innovations can also be useful for spoken languages. In the future, the approach taken in this study might contribute to developing best practice models for promoting sign language vitality and compile diachronic data to monitor changes in endangerment status. The findings can also inform policy work to bring about legal recognition, greater communication access, and the protection of deaf signers’ linguistic and cultural identity.
