Summary
"People who first encounter sign language often ask if deaf people around the world sign the same language. Frequently, they are surprised to learn that there are different sign languages in different nations worldwide, as well as variations of these languages. These variations depend on social factors such as region, age, gender, socioeconomic status, and race. One variation, Black ASL, has been recognized for years as a distinct form of sign language but only through anecdotal reports.
