Across the world, روسان (Rosan 
, Rousan 
, روسان 
) is a common epicene forename. The forename روسان is characteristic of Qatar, where it is quite a common mostly masculine, but seldom feminine name, India, where it is quite a rare epicene name, and Saudi Arabia, where it is quite a rare largely boy's, but uncommonly female name. Not in comparison with a country's population, the name is most common in India, Philippines, and Saudi Arabia. Much less frequently, روسان is the last name as well as the forename.
