The Bago (Bago Igorot) were identified first in the municipality of Pugo in the southeastern side of La Union. This is a highly acculturated group whose villages are along major transporation routes between the lowlands and the Abatan, Benguet markets in the highland. The major ritual practices and beliefs are somewhat related to the northern Kankanay, thus the idea that the people were migrants because of trade from western Mountain Province. The Kankanay regard them as such and not as a specific ethnic group. The language is a mixture of northern Kankanay with an infusion of lowland dialects. Most of the individuals are bilingual with Ilocano as the trade language.

       Their agricultural activities revolve around a mixture of highland root crops like sweet potatoes, yams, and taro, and lowland vegetables and fruits.
