Bethel is the main population center and service hub, with an estimated population of about 6,219 as of 2011, and is surrounded by 49 smaller villages. The largest villages have over 1,000 people [1].
Subsistence and Economy
Most residents live a traditional subsistence lifestyle of hunting, fishing and gathering. More than 30% have cash incomes well below the federal poverty threshold [1]. Calista Corporation, assigned land under ANCSA in 1971, covers a region of 56 villages and about 23,000 people [2].
