The capital of this province is the city of Yauyos. The province extends over an area of 6,901.58 square kilometers (2,664.71 sq mi) and is divided into 33 districts:

Yauyos Alis Ayauca Ayaviri Azángaro Cacra Carania Catahuasi Chocos Cochas Colonia

Hongos Huampara Huancaya Huangascar Huantán Huañec Laraos Lincha Madean Miraflores Omas

Putinza Quinches Quinocay San Joaquín San Pedro de Pilas Tanta Tauripampa Tomas Tupe Viñac Vitis

The province has a population of 28,000 inhabitants as of 2002. One distinctive cultural trait of the province is that the Tupe district is home to the small ethnic minority who speak the indigenous Jaqaru/Kawki language, a linguistic curiosity as the only surviving relative of Aymara, spoken far to the south in the Altiplano. Besides that, several archaic Quechua dialects are spoken in some districts (Huacarpana, Apurí, Madean, Viñac, Azángaro, Huangáscar, Chocos, Cacra, Hongos, Tanta, Lincha, Tomás, Alis, Huancaya, Vitis, and Laraos). However, all these dialects and languages, respectively, are in danger of extinction.
