All over the world, 西亞 (Shia 
, 西亞 
) is quite a rare gender-neutral first name. The first name 西亞 is characteristic of Guatemala, where it is a rare female name, Singapore, and Saudi Arabia, where it is a rare epicene name. Not in comparison with a country's population, it is commonest in India, Indonesia, and the United States. More prevalently, 西亞 is the last name as well as the forename.
