British Sign Language (BSL) is the language used by the deaf community in the United Kingdom. In this chapter, we describe sociolinguistic variation and change in BSL varieties in England. This will show how factors that drive sociolinguistic variation and change in both spoken and signed language communities are broadly similar.
