On April 15, 1817, the American School for the Deaf opened. That date is now marked every year by ASL Day.
Today, around one million people use American Sign Language (ASL) as their main way to communicate, according to Communication Service for the Deaf. Used by the deaf and hard-of-hearing communities, as well as those with communication disorders, in recent years it has received more resources and attention both online and in popular culture.
But there are still major barriers for many in these communities and there is a call for more early education from organizations such as the Department of Health, National Association of the Deaf (NAD) and others.
In celebration of the one million Americans using this language, we have put together a guide to help all Americans understand how ASL is used, the barriers faced by those who use it and ways in which we can all be inclusive to those communities.
ASL: A history
According to the National Institute for Deafness and other Communication Disorders (NIDCD), it is suggested ASL was first used over 200 years ago. Influenced by French Sign Language (LSF) with some original local signs, it is used by one million Americans.
As with spoken languages, sign languages across the world are different. There are 300 distinct sign languages across the world.
