This paper aims to identify housing disadvantages faced by migrants and ethnic minorities; the legal, policy and market forces that shape them; how they have developed over time; how they are manifest nationally and locally; and how they are being responded to locally by those concerned with mitigating them. The paper thereby intends to provide a foundation to inform future research and policy and to engage with local actors to develop ways of overcoming migrant housing disadvantage and challenging discrimination. The paper finds that the interplay of legal changes, which have increasingly differentiated migrants since the 1940s, and shifting housing markets, has driven exclusion of migrants and minorities such that considerable disadvantage is revealed by analysis of census data. However, attention to local specificity provides evidence of positive responses. Examples are presented in relation to access to affordable housing, enactment of homelessness duties and community actions. Methodologically, this paper highlights the importance of simultaneous consideration of migration and ethnicity as markers of difference and exclusion, and the potential of co-production approaches for socially meaningful research concerned with inequalities.
