ethnic origin that has the purpose or effect of nullifying or impairing the recognition, enjoyment or exercise, on an equal footing, of human rights and fundamental freedoms in the political, economic, social, cultural or any other field of public life. In their 1978 United Nations Educational, Scientific, and Cultural Organization (UNESCO) Declaration on Race and Racial Prejudice (Article 1), the UN states, "All human beings belong to a single species and are descended from a common stock. They are born equal in dignity and rights and all form an integral part of humanity." The UN definition of racial discrimination does not make any distinction between discrimination based on ethnicity and race, in part because the distinction between the two has been a matter of debate among academics, including anthropologists. Similarly, in British law, the phrase racial group means "any group of people who are defined by reference to their race, colour, nationality (including citizenship) or ethnic or national origin". In Norway, the word "race" has been removed from national laws concerning discrimination because the use of the phrase is considered problematic and unethical. The Norwegian Anti-Discrimination Act bans discrimination based on ethnicity, national origin, descent, and skin color. Social and behavioral sciences Sociologists, in general, recognize "race" as a social construct. This means that, although the concepts of race and racism are based on observable biological characteristics, any conclusions drawn about race on the basis of those observations are heavily influenced by cultural ideologies. Racism, as an ideology, exists in a society at both the individual and institutional level. While much of the research and work on racism during the last half-century or so has concentrated on "white racism" in the Western world, historical accounts of race-based social practices can be found across the globe. Thus, racism can be broadly defined to encompass individual and group prejudices and acts of discrimination that result in material and cultural advantages conferred on a majority or a dominant social group. So-called "white racism" focuses on societies in which white populations are the majority or the dominant social group. In studies of these majority white societies, the aggregate of material and cultural advantages is usually termed "white privilege". Race and race relations are prominent areas of study in sociology and economics. Much of the sociological literature focuses on white racism. Some of the earliest sociological works on racism were written by sociologist W. E.
