In all the world, Gaija (Gaj 
, Gaija 
) is a common dominantly masculine, but infrequently girly given name. The first name Gaija is habitual in Slovenia, where it is quite a rare boy's name, India, where it is a rare largely boy's, but uncommonly female name, and Croatia, where it is a rare male name. Not in comparison with a country's population, the name is most common in India, Pakistan, and Slovenia. Much less frequently, Gaija is the last name as well as the forename.
