The Cagayan Valley and Caraballo ethnolinguistic groups are a collection of indigenous peoples primarily residing in the Cagayan Valley region and the Caraballo and Sierra Madre mountain ranges of northern Luzon, Philippines. Unlike the Igorot people of the Cordillera Central, these groups do not share a common exonym and identify as distinct ethnic entities with their own unique cultures, languages, and traditions. The Cagayan Valley and Caraballo groups are composed of the following:
The Ilongot (Bugkalot) are a tribe who inhabit the southern Sierra Madre and Caraballo Mountains, on the east side of Luzon in the Philippines, primarily in the provinces of Nueva Vizcaya and Nueva Ecija and along the mountain border between the provinces of Quirino and Aurora. An alternative name of this tribe and its language is "Bugkalot". They are known as a tribe of headhunters. Presently, there are about 18,000 Ilongots. The Ilongots tend to inhabit areas close to rivers, as they provide a food source and a means for transportation. Their native language is the Ilongot language, the number of speakers is reported to be at 5,710 according to the 2010 census, classifying the language as threatened (EGIDS 6b). They also speak the Ilocano & Tagalog languages, the latter is spoken in Nueva Ecija & Aurora as much as Ilocano.
The Isinai/Isinay are a small ethnic group living in the Cagayan Valley, specifically in the municipalities of Bambang, Dupax del Sur, Aritao in Nueva Vizcaya, as well as around Quirino province, and in the northern areas of Nueva Ecija and Aurora. Their ethnic communities show a decline in population, with only around 12,600 members on record. They speak the Isinai language (also spelled Isinay), which is a Northern Luzon language primarily spoken in Nueva Vizcaya province in the northern Philippines. By linguistic classification, it is more divergent from other South-Central Cordilleran languages, such as Kalinga, Itneg or Ifugao and Kankanaey.
The Ibanags are a predominantly Christian lowland ethnic group numbering around half a million people and who primarily inhabit the provinces of Cagayan and Isabela in the Cagayan Valley of northern Luzon. They speak the Ibanag language, which is distantly related to Ilocano, which they speak as second language.
The Itawes/Itawis/Itawit are among the earliest inhabitants of the Cagayan Valley in northern Luzon. Their name is derived from the Itawes prefix i- meaning "people of" and tawid or "across the river". As well as their own Itawis language, they speak Ibanag and Ilocano. The contemporary Itawes are charming, friendly, and sociable. They are not very different from other lowland Christianized Filipino ethnic groups in terms of livelihood, housing, and traditions. Their traditional dresses are colorful with red being the dominant color. Farming is a leading source of livelihood. The average families are education-conscious.
The Malaweg are located in sections of Cagayan Valley and Kalinga-Apayao provinces and in the town of Rizal. Their main crops are lowland rice and corn. Tobacco was raised as a cash crop on a foothill west of Piat on the Matalag river near the southeast border of Kalinga-Apayao province, drawing Ibanags from the east. Culturally, they are similar to the neighbor groups: Ibanag and Itawis. Linguistically, they speak a dialect of Itawis.
The Gaddang number about 25,000. They are known to have inhabited the upper Cagayan Valley and the Magat valley below Aritao in Nueva Vizcaya and in Isabela since before the Spanish arrived. Main centers of their language are found in Ilagan, Santiago, Cauayan, Solano, Bagabag, and Bayombong, as well as surrounding towns. Speakers from each municipality have significantly characteristic vocabulary, usage, and pronunciation, although they understand each other well. Their language is related to Ibanag and Itawis; it is also spoken by ethnically related highland Ga'dang in the provinces of Ifugao Province, Kalinga Province, and Mountain Province.
The Yogad are 15.00% christian and are one of the smallest minority groups in the region of the Cagayan Valley. They once occupied Diffun, Quirino in Cagayan Valley. Today, they are concentrated in Echague, Camarag, Angadanan, Santiago, and Jones, Isabela. Yogads speak the Yogad language, which is one of the five recognized dialects of Gaddang, and are identified as part of the Christianized Kalingas in western Isabela.
