Demographics
The majority of people living in Cagayan are of Ilocano descent, mostly from migrants coming from the Ilocos Region. Originally, the more numerous group were the Ibanags, who were first sighted by the Spanish explorers and converted to Christianity by missionaries. This is why the Ibanag language spread throughout the area prior to the arrival of Ilocanos.
Aside from Ilocanos and Ibanags, Malauegs, Itawits, Gaddangs, groups of nomadic Aetas, as well as families of Ibatans who have assimilated into the Ibanag-Ilocano culture make Cagayan their home. More recently, a new group from the south, the Muslim Filipinos, have migrated to this province and have made a community for themselves. In addition to this, Tagalog-speaking people from the Southern Luzon have also settled in the area. Because of this influence from other majority groups like the Ilocano from the west and the Tagalog from the south, the smaller ethnic groups living in the valley could potentially go extinct.
