The Ethnologue lists South Bolivian Quechua as "developing", which indicates that "the language is in vigorous use, with literature in a standardized form being used by some though this is not yet widespread or sustainable." However, UNESCO's Atlas of Endangered Languages categorizes South Bolivian Quechua as "vulnerable", defined as the following: "Most but not all children or families of a particular community speak the language as their first language, but it may be restricted to specific social domains (such as at home, where children interact with their parents and grandparents)."
