White people is a term which usually refers to human beings characterized, at least in part, by the light pigmentation of their skin. It often refers narrowly to people claiming ancestry exclusively from Europe.[1][2] A broadly corresponding and sometimes synonymous concept is the Caucasian race.[3] Caucasoid people from the Middle East, North Africa, and parts of Central, and South Asia , are therefore also sometimes considered "White" and related to European people.[3][4]
