Abra, the Itnegs’ territory, lies in between the provinces of Ilocos Norte, Ilocos Sur, Mountain Province, Kalinga, and Apayao. Their economic activities include swidden farming, fishing, and hunting; their staple crop is rice (planted using both dry and wet methods). Itneg villages are usually composed of around 50 households, all of whom are related to each other.
Also known as Tingguian, the Binongan Itneg are found in Licuan-Baay. Their language has similarities with Ilocano and Masadiit Itneg; they use it enthusiastically.
