White people (also the Caucasian race) is a term usually referring to human beings characterized (at least in part) by the light pigmentation of their skin. Rather than being a straightforward description of skin color, the term white denotes a specific set of ethnic groups and functions as a color metaphor for race.
The most commonly-used definition of "white person" is "a person with a visible degree of European ancestry". However, the definition of "white person" differs according to geographical and historical context. Various social constructions of whiteness have had implications in terms of national identity, consanguinity, public policy, religion, population statistics, racial segregation, affirmative action, eugenics, racial marginalization and racial quotas. The concept has been applied with varying degrees of formality and internal consistency in disciplines including sociology, politics, genetics, biology, medicine, biomedicine, language, culture and law.
The notion of "white people" or a "white race" as a large group of populations contrasting with non-white or "colored" originates in the 17th century. Pragmatic description of populations as "white" in reference to their skin color predates this notion and is found in Greco-Roman ethnography and other ancient sources.
The term black people is used in some socially-based systems of racial classification for humans of a dark-skinned phenotype, relative to other racial groups represented in a particular social context. Different societies apply different criteria regarding who is classified as "black", and often social variables such as class and socio-economic status also play a role, so that relatively dark-skinned people can be classified as white if they fulfill other social criteria of "whiteness" and relatively light-skinned people can be classified as black if they fulfill the social criteria for "blackness" in a particular setting.
As a biological phenotype being "black" is often associated with the very dark skin colors of some people who are classified as "black". But, particularly in the United States, the racial or ethnic classification also refers to people with all possible kinds of skin pigmentation from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have African ancestry, or to exhibit cultural traits associated with being "African-American". As a result, in the United States the term "black people" is not an indicator of skin color but of socially based racial classification.
