Cahitas, a large Mexican nation, states of Sonora and Sinaloa, along the east side of the Gulf of California between lat. 26° and 28° N., and inland nearly as far as the Tarahumaras. The Cahitas, who include the Yaquis, Tehuecos, and Mayos farther south, constitute one of Buschmann's four "Aztec-Sonora" groups, with speech betraying certain affinities to Aztec. The other three groups are the Cora, Tarahumara, and Tepehuana. The Cahitas are a mild, sociable people, very industrious, endowed with great intelligence, and courageous. Total population about 20,000, being much reduced by the emigration of the young men, who seek employment in large numbers in the towns and farmsteads of the neighbouring provinces.
