Explore Deaf Community in more detail :
There is a long history of people who are Deaf, and share a language – sign language, a visual language. However, the majority of Deaf people were and are born into hearing families, where the language of the home is a hearing one, rather than a sign language. At least 95% of deaf children are born into hearing families. The community in which the Deaf person could share communication was therefore not usually the home and family, but one in which others were also deaf, and considered themselves to be Deaf, with communication using a sign language. The Deaf community is therefore one in which the community and its culture arises from shared language, experiences and common ground, rather than on familial links.
