Also called the Paranan, the Palanan group is largely concentrated on the Pacific side of the province of Isabela about Palanan Bay. The population areas are in Palanan (9,933) with a total population of some 10,925 (NSO 1980). This is probably the northeasternmost extension of the Tagalog language. There is, however, a considerable mixture with the culture of the Negrito. The coastal area is narrow with the Sierra Madre looming precipitously and hemming the land in on the west with the Pacific Ocean on the east. The subsistence technology is oriented to the ocean close by with patchwork swidden cultivation of rice on the slopes.
