- Population
- 408,000 in United States, all users. L1 users: 277,000 in United States (Mitchell et al 2006). Mitchell et al 2006 estimate no more than 277,000 in 1972 who were prevocationally deaf; more recent figures unavailable but an estimate based on 0.1% of total population for 2019 would be 325,000. L2 users: 131,000 (Mitchell et al 2006). Total users in all countries: 860,605 (as L1: 729,605; as L2: 131,000).
- Location
- Scattered, especially in urban centers and near (present or former) residential deaf schools.
- Language Maps
- Sign Languages of Africa, Sign Languages of Asia, Sign Languages of the Americas, Sign Languages of the Pacific
- Language Status
- 5 (Developing). Provincially recognized language in various states, state laws cover a variety of issues: approving ASL for college credit, regulating interpreter services, deaf children’s education, etc. Recognized language (1990, Americans with Disabilities Act, ADA), requires governments, nonprofit organizations and private businesses to make their services accessible to deaf people, and mandates equal access to telecommunications services.
- Classification
- Sign language, Deaf community sign language
- Dialects
- Black American Sign Language (BASL, Black ASL), Tactile American Sign Language (TASL, Tactile ASL). Some lexical variation across the United States and Canada (except Quebec), but intelligibility is high among all varieties called ASL. Black American Sign Language, which developed among African-American children in segregated schools in the southern United States, contains some distinctive vocabulary, grammatical structure, and phonological properties (McCaskill et al 2020). Tactile ASL (TASL) is used throughout the United States by and with deaf-blind people, especially those with Usher’s Syndrome, concentrations of whom are found in Louisiana and Seattle. TASL uses ASL vocabulary and grammar, except (1) signs are perceived by holding the signer’s hands and following them around, and (2) there are modifications to compensate for lack of access to the signer’s facial expressions and other parts of the body that are not being touched. Since 2007, in Seattle and elsewhere, more substantial structural changes have occurred as a result of innovations by deaf-blind people that employ the unique characteristics of touch (Edwards 2014, Edwards and Brentari 2020), such as articulating signs on the listener’s body. This has resulted in a new variety called Protactile that is not mutually intelligible with (visual) ASL and TASL (Granda and Nuccio 2018), although as yet it does not have a separate ISO 639-3 code. Indeed, Protactile exemplifies a new modality of language: a tactile language, one structured around touch rather than sound or sight. Some deaf-blind people learn Braille for reading English. Varieties of ASL or closely-related languages derived from ASL are used in many other countries, particularly in the Caribbean and Africa; they are typically referred to either as ‘ASL’ (despite their differences) or by a name based on their country name. Some of these still use the ISO code [ase] but are different enough that they probably should acquire their own separate code. Lexical similarity: 58% between modern ASL and French Sign Language (LSF) [fsl] on a comparison of 872 signs (Woodward 1978b). Although the 2 are historically related, ASL has undergone substantial creolization (Woodward 1975, Woodward 1976).
- Typology
- One-handed fingerspelling system derived from French Sign Language [fsl]. SVO, topic comment structures; adjectives, numerals, genitives, question word initial or final, relative clause after noun head.
- Language Use
- Interpreters required for many legal and civic situations. Lingua franca of the deaf world, used widely as L2 in many countries other than those listed here. Used by all. Many also use English [eng]. Fluency in English varies widely, from native (hearing children of Deaf parents), or near-native in reading/writing (many Deaf professionals), to ability only to read individual English words. Used as L2 by Hawaii Sign Language [hps], Plains Indian Sign Language [psd].
- Language Development
- Literacy is almost always based on English rather than ASL. Deaf people’s English varies from highly literate to illiterate, but the average deaf student graduates from high school with a third or fourth grade reading level. TV. Videos. Dictionary. Grammar. Bible: 2020.
- Other Comments
- American Sign Language is different from Signed English, a range of signing registers influenced by English. Signing Exact English (SEE) and Seeing Essential English (SEE2) are artificially-constructed systems that attempt to match English word order and morphemic structure exactly. Pidgin Signed English (PSE) does not follow English grammar exactly, and is sometimes referred to as ‘contact signing’. Deaf schools and interpreters in mainstreamed educational settings may use any of these sign varieties. The alternate name ‘SIGN AMERICA’ is a representation of the signs that sign language users in other countries often use for ASL. This name is not used in English, but is a word-for-sign translation of the signed name.

The relationship of signing in Côte d’Ivoire to standard ASL in the United States and to LSAF in other francophone African countries has not been assessed. Further, there is significant variation within the country, again not systematically assessed, and a variety of names used. Some people regard these names as referring to distinct languages, others as dialects of the same language. Some deaf know more than one variety. There is also a local variety in the village of Bouakako, Hiré in southwestern Côte d’Ivoire. (2013 A. Tano). View other languages of Côte d’Ivoire

The sign language commonly used by the deaf community in Haiti is currently reported as a dialect of ASL, but many regard it as a separate language, as there are significant lexical and grammatical differences and challenges to mutual intelligibility. ASL tends to be used in schools and with foreigners, which has hidden the separate existence of LSH from outsiders (Hochgesang and McAuliff 2016). View other languages of Haiti

American Sign Language
- Location
- Scattered, mostly in and around San Salvador.
- Dialects
- None known. ASL users in El Salvador have considerable difficulty understanding ASL from the United States (Ciupek-Reed 2012), so it probably should be regarded as a separate language from standard ASL. Salvadoran ASL includes signs from Salvadoran Sign Language (LESSA) [esn], and reflects Spanish influence in initialized signs and grammar. It is perhaps better described as Signed Spanish based on ASL vocabulary (Ciupek-Reed 2012).
- Language Status
- 6b (Threatened)
- Language Use
- Previously used in one private educational institution and by their graduates (Ciupek-Reed 2012); that school has now closed. Its graduates generally learned LESSA upon graduation for interaction with the wider deaf community. Used mostly only by adults who attended the school (2020 S. Shannon). Also use Salvadoran Sign Language [esn]. Used as L2 by Salvadoran Sign Language [esn].

- Non-indigenous. Since LSAF is not recognized by ISO 639-3 as a distinct language, it must be treated here as a dialect of ASL, with influence from spoken and written French [fra] (initialization of signs and mouthing) and addition of local signs. The relationship of ASL and LSAF in Mali to standard ASL in the United States and to LSAF in other francophone African countries has not been systematically assessed (Nyst 2015). The name ‘Malian Sign Language’ is used both for this variety, influenced strongly by ASL and here called LSAF, and for a more traditional and indigenous variety centered in Bamako, sometimes called Bamako Sign Language [bog].
