One decade after its introduction, the superdiversity concept introduced by Steven Vertovec has widely found echoes in migration research, but also in business studies, particularly those focusing on ethnic minority entrepreneurship (EME). In spite of conceptually embracing superdiversity in EME research, the multi-dimensionality of superdiversity in its original understanding appears to require further consideration. Dimensions currently overlooked in research at the nexus of superdiversity and ethnic minority entrepreneurship are: (1) ethnic but also religious and linguistic diversity of entrepreneurship, (2) entrepreneurial diversity regarding business-types and (3) incorporation of the characteristics of the city within its analytical unit. Based on an extensive site survey of ethnic businesses in Glasgow combining ethnographic assessment and available statistical data on the city districts, this paper reconceptualizes the entrepreneurial superdiversity to do justice to the on-going debates on superdiversity within migration research. In doing so, it proposes the Entrepreneurial Superdiversity Index (ESI), which is a viable method for approximating entrepreneurial superdiversity in cities. The ESI allows comparative analyses of entrepreneurial superdiversity within a specific city and potentially also between different cities internationally, which could be highly useful for policy-makers and planners alike. It also delivers grounds for developing a general index for superdiversity in further migration research.
