Globally, Dasia (Dasia 
, Дася 
) is quite a rare unisex first name. The forename Dasia is habitual in the Democratic Republic of the Congo, where it is a rare feminine name, Nicaragua, and the United States, where it is a rare primarily girly, but very seldom boy's name. Not in comparison with a country's population, it is commonest in India, the United States, and the Democratic Republic of the Congo. Much less frequently, Dasia is the last name as well as the forename.
