Decoliat
Located on the West of Aurora province, Decoliat is the most multilingual community. Besides Northern Alta, languages like Tagalog, Ilocano, Ilongot, Kankana-ey, Igorot, Ifugao can be heard. As opposed to other communities, the teachers use Ilocano at school (instead of Tagalog). Most of the children appear to be bilingual Tagalog-Ilocano, and are in some cases, fluent in their ethnic language.
