The racial predilection depends on the cause of the biliary obstruction. Gallstones are the most common cause of biliary obstruction. Persons of Hispanic origin and Northern Europeans have a higher risk of gallstones compared to people from Asia and Africa.

Native Americans (particularly Pima Indians) have an increased incidence of obesity and diabetes within their population and are especially prone to developing gallstones. Pima women have a lifetime chance of developing gallstones as high as 80%.

Gall bladder cancer is more common in Central and South America, Central and Eastern Europe, the northern Indian subcontinent and East Asia (Japan and Korea). Oriental cholangiohepatitis (OCH) is seen in the Far East.
