Cocopa, Kiliwa, Kumiai (and Tipai), Paipai
The majority of the languages in the Yuman family are found in the state of Baja California Norte (apart from the other languages of this family, which are found today only in California and Arizona in the U.S.). Cocopa is spoken in Sonora and also in the state of Arizona. All of these languages are considered endangered.
Some speakers of the Tipai subvariety of Kumiai use the name Cochimi to refer to themselves; linguists usually use that name to refer to a group that is now extinct. There is another language in this family, closely related to Tipai according to some linguists, spoken in Santa Catarina by a very small group, also referred to as Ko'al.
The Yuman languages have long been considered to be part of the putative Hokan stock.
