Here's a breakdown:
* United States: ASL is the primary language of the Deaf community in the US, with an estimated 500,000 to 2 million users.
* Canada: ASL is also used in Canada, particularly in the eastern provinces, along with Canadian Sign Language (CSL).
* Other countries: ASL is also found in other countries, often as a result of historical connections with the US or through the influence of Deaf education. For example, some Deaf communities in Mexico, the Philippines, and parts of Africa use ASL.
It's important to note:
* There are many different sign languages used around the world, with each one having its own unique structure and vocabulary.
* While ASL is the dominant sign language in the US, other sign languages are also used, such as Signed English and various regional sign languages.
Overall, while ASL is primarily an American sign language, its use extends beyond the United States, with various Deaf communities around the globe adapting and utilizing it for communication.
