Using the findings of ethnographic fieldwork conducted at an inner-city football club, the article examines the relationship between superdiversity and understandings of human variation. It is argued that club personnel relied on what I have termed ‘granular essentialisms’ to make sense of their superdiverse surroundings. These were assertions about ethnicity and ‘race’ that resulted from sustained engagement across various categories of difference and saw these categories intersected in various ways, with notions of space and place being invoked in the process. This granular approach is compared with the attitudes to migration-related diversity encountered outside the inner city. I conclude that proponents of superdiversity should take greater account of the inequalities, tensions and prejudices evident in and around superdiverse areas if they are to construct a more comprehensive picture of the lived realities of contemporary cities and the understandings of ethno-racial difference which take hold there.
