Chipaya has over a thousand speakers and sees vigorous use in the native community, but all other Uru languages or dialects are extinct.
Loukotka (1968) also lists the Chango language, once spoken on the coast of Chile from Huasco to Cobija in Antofagasta Province. The population has since been Araucanized.[1]
