Demographics in the formation of language communities and in the emergence of languages: The early years of ASL in New England

How may the structure of a new linguistic community shape language emergence and change? The 1817 founding of the US’s first enduring school for the deaf, the American School for the Deaf (ASD) in Hartford, Connecticut, heralded profound changes in the lives of deaf North Americans. We report the demographics of the early signing community at ASD through quantitative analyses of the 1,700 students who attended the school during its first fifty years. The majority were adolescents, with adults also well represented. Prior to 1845, children under age eight were absent. We consider two groups of students who may have made important linguistic contributions to this early signing community: students with deaf relatives and students from Martha’s Vineyard. We conclude that adolescents played a crucial role in forming the New England signing community. Young children may have pushed the emergence of ASL, but likely did so at home in deaf families, not at ASD.*
