In these transactions Banjar typically act as middle men between the Meratus and other traders. Social organization Most Meratus live and farm in umbun which are also considered the primary social units among the Meratus Dayak. Umbun are founded by a man and a woman, usually a married couple, but sometimes also a brother and sister, a widow and her adult son, or other male-female pairs. Umbun also embrace a variety of dependents who have not yet founded their own umbun, including children and recently married, disabled, and widowed adults. The founding pair is responsible for the umbun. Some Meratus have also been moved into villages by government resettlement programs. The Meratus are classified as a "semi-nomadic" isolated tribe, and are the target of government development programs as such.
