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.
The Moyadan Itneg language is also known as Tingguian, and has lexical similarities with that of the Masadiit Itneg.
