In the world, Biak (Biak 
) is quite a rare primarily male, but scarcely feminine given name. The forename Biak is habitual in Mongolia, where it is quite a common male name, Myanmar, where it is a rare epicene name, and Australia, where it is a very rare unisex name. Not in comparison with a country's population, it is the most numerous in Mongolia, Myanmar, and India. Very seldom, Biak is the last name as well as the forename.
