Ilocos

Ilocos collectively refers to two provinces in the Philippines: Ilocos Norte and Ilocos Sur who used to be a single province. Inhabitants are called Ilocanos and they speak the language Iloko, also called Ilocano.
The Ilocos Region, containing four provinces, is named after Ilocos. 56 percent of the inhabitants of the region are Pangasinan people, who belong to a different ethnolinguistic group from the Ilocanos. Ilocos may also refer to the former province before Ilocos Norte and Ilocos Sur were divided.
