These categories are also identity-constructing. One of the chief claims made by Barker is that these categories of ethnicity, race and nation are nodal points of identity and subjectivity. They are points of convergence. We can also say that these in themselves are sites of identity and subjectivity. A knowledge of the concepts of Identity and subjectivity (being among the key concepts of Cultural Studies) therefore enable us to claim that if identity and subjectivity are constructed, performed or played out within the categories of ethnicity, race and nation which are cultural categories, then the latter are also sites of culture.

We can see how the studies of ethnicity, race and nation differ in Cultural Studies particularly when we compare these to the explorations done in the domains of anthropology, sociology and political science. There are overlaps but considering these as discursive and performative belongs particularly to the methodology of Cultural Studies.
