Quechua, Jauja Wanca

The 2017 census in Peru registered a much smaller number of Quechua speakers in the province where the language is spoken than the one that Ethnologue currently gives and which dates back to the 1962 census. Also, as Dr. Rodolfo Cerrón-Palomino, a leading authority on Wanca Quechua, shows in his research on Wanca Quechua, not all of the province of Jauja speaks this language: eight (8) districts in the southeast of the province speak Huaylla Wanca Quechua [qvw].  Quechua speakers in those eight districts numbered 522 in 2017.  Thus, if we detract 522 from the figure of 3,696 Quechua speakers in the province of Jauja registered by the 2017 census, we get 3,174 Quechua speakers in the rest of Jauja province. I would thus estimate the 2017 speaker population of this language under 5,000.
