Oxford research, based at the ESRC-funded Centre on Migration, Policy and Society (COMPAS), on ‘superdiversity’ and transnationalism has directly influenced the formulation and framing of UK and European policy on migration and integration. Through constant interaction with policymakers and practitioners, engaged research at COMPAS has enabled the concept of ‘superdiversity’, firsttheorised by Vertovec, to be widely utilised in the consequent formulation of new policies for migrant integration and local governance at both central and local levels. In particular, this research has influenced central government policy on integration and cohesion, and on antidiscrimination law, and local government practice. These policies now reflect new diversities of faith, gender, disability, age and sexual orientation, alongside difference in terms of ethnicity.
