What Constitutes Substantive Representation, and Where Should We Evaluate It?

This short article introduces a novel framework for conceiving of the substantive representation of marginalized groups – in this case, racially minoritized women in the UK House of Commons. I outline a rubric of eight facets of substantive representation. These evaluate the degree to which claims that constitute a group are also substantively representative of that group. In doing so, I contribute a much-needed framework for distinguishing between representative claims which speak on behalf of a group versus those which merely speak about, or even against, that group. I argue that substantive representation must be considered intersectionally, reflecting the multiple structures positioning those represented. Furthermore, all facets of substantive representation can rarely be contributed by a single parliamentary speech, individual, or narrow group of legislators such as descriptive representatives. Therefore, I suggest that empirical studies of substantive representation should include a greater evaluation of the collective work of institutions as a whole.
