This article introduces a collaborative publication exploring the intricate interplay between poverty governance, migration control, and welfare provision. Adopting a ‘keywords’ approach, we investigate the terminology and concepts around which academic discussions revolve when addressing poverty and migration. Central to this examination is the figure of the ‘poor migrant’, whose experiences of inclusion and exclusion intersect along lines of race, gender, and legal status. Using an intersectional lens, the publication dissects key terms and concepts : Welfare State, Welfare Governance, Citizenship, Solidarity and Deservingness, Suspicion and Surveillance, Discipline, and Banishment. We thus aim to conceptualise and critically discuss the constant renegotiation of state power and the nation-state induced in ex/inclusionary aspects of welfare and migration policies and law. The contribution reveals how notions of belonging shape access to rights and services, particularly along racialized and classist lines. Moreover, it explores how migration policies exacerbate scrutiny and exclusion faced by non-citizen populations within contemporary welfare systems.
