Across the world, 大哥 (大哥 
, Dage 
, Đại Ca 
) is quite a rare mostly boy's, but uncommonly female given name. The forename 大哥 is habitual in Sub-Saharan Africa, particularly the Democratic Republic of the Congo, where it is quite a rare dominantly boy's, but seldom female name, Ethiopia, where it is quite a rare male name, and Nigeria, where it is a rare epicene name. Likewise, 大哥 is the last name as well as the forename.
