<p>Structural discrimination is sometimes presented as a unique subtype of discrimination. Yet, it is unclear how this concept should be defined. I argue that structural discrimination against a group G obtains when (1) G is a social group in society S; (2) members of G typically experience enduring, cross-cutting comparative disadvantages that are plural, multi-facetted, and that affect different significant spheres of life; and (3) the comparative disadvantages are created by the combined effects of different interdependent social practices. I show how structural discrimination is distinct from individual instances of direct and indirect discrimination and that this concept is different from the notion of structural injustice.</p>
