To date little attention has been focused on how the differing features of ‘superdiverse’ neighbourhoods shape residents’ access to healthcare services. Through utilising a cross-national mixed-methods approach, the paper highlights how defining features of superdiverse neighbourhoods - ‘newness’, ‘novelty’ and ‘diversity’ - influence a number of neighbourhood ‘domains’ and ‘rules of access’ that regulate access to healthcare. Issues of uncertainty, affordability, compliance, transna- tionalism and the diversity of community and local sociability are identified as being particularly significant, but which may vary in importance according to the nationality, ethnicity and / or religion of particular individuals.
