In the world, Баю (Bayu 
, Baju 
, Баю

The first name Баю is characteristic of Indonesia, where it is quite a common predominantly male, but scarcely girly name, Ethiopia, where it is quite a common unisex name, and Bulgaria, where it is quite a rare masculine name. In absolute terms, this name is the most popular in Indonesia, Ethiopia, and India. Much less frequently, Баю is the last name as well as the forename.
