It's a very wide classification. https://en.wikipedia.org/wiki/Caucasian_race >First introduced in the 1780s by members of the Göttingen school of history,[b] the term denoted one of three purported major races of humankind (those three being Caucasoid, Mongoloid, and Negroid).[12] In biological anthropology, Caucasoid has been used as an umbrella term for phenotypically similar groups from these different regions, with a focus on skeletal anatomy, and especially cranial morphology, without regard to skin tone.[13] Ancient and modern "Caucasoid" populations were thus not exclusively "white", but ranged in complexion from white-skinned to dark brown.[14]
