Abstract

This article aims to challenge normative representations of European integration that foreground EU membership as a structuring principle. In scholarly literature, differentiation is increasingly recognized as a structural feature of the EU rooted in heterogeneous preferences and capacities between countries. Despite that, conventional maps continue to represent European integration as monolithic blocs defined by de jure ratification of treaties rather than variegated geographies driven by de facto heterogeneity of preferences and capacities. To map these variegated geographies, this article conceptualizes heterogeneity in terms of dynamic proximity and proposes an original mapping methodology based on cluster analysis. The results of the analysis show that different geographies of proximity between countries appear on the map depending on the dimension (institutional or organizational proximity) and the year (2000, 2010 or 2019) considered and that these geometries can only partially be traced back to bordering processes associated with EU membership.
