12701 Assiniboine 100-999 None under 40 and most elderly. 3,500 Dakotan is a Siouan dialect complex, with three well defined dialect areas: Stoney, currently spoken in southwestern Alberta; Assinibone, in southern Saskatchewan and northern Montana; and Sioux, spoken widely in North and South Dakota, Minnesota, and in southern Manitoba and Saskatchewan. Intelligibility between these dialect areas is low, although speakers can communicate after a while with some difficulty, and they are perhaps best considered emergent languages.
