indigenous citizens of
Quechua descent.
Quechua is the language which the majority of the population (91.07%) learnt to speak in childhood, 8.62% of the residents started speaking in
Spanish (
2007 Peru Census). Because of the
migration of a high number of rural people to the towns the
Spanish language (
