Throughout the world, Рося (Rosia 
, Rosya , Рося 
) is a common principally female, but very infrequently boy's first name. The forename Рося is habitual in the Democratic Republic of the Congo, where it is quite a common primarily female, but very infrequently male name, Israel, where it is a rare girly name, and Indonesia, where it is a rare predominantly girly, but very infrequently masculine name. Not in comparison with a country's population, it is the most numerous in the Democratic Republic of the Congo, the United States, and Indonesia. Very seldom, Рося is the last name as well as the forename.
