Their language is referred to as Dha-Anywaa. They primarily reside in the Gambela Region of western Ethiopia, and South Sudan. Group members number between 200,000 and 300,000 people worldwide. Many of the Anyuak people now follow Christianity. It is one of the first of the Nilotic groups to become almost entirely Christian, following the Shilluk people.
