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".
