Beyond DEGURBA: A multi-functional typology of EU non-urban regions

Rural classification in the European Union has long relied on the Degree of Urbanisation (DEGURBA), a density-based framework that delimits urban from non-urban territories but does not differentiate among the functional types of rurality within that boundary. This paper operationalises the Rural Diversity Compass – a multi-functional framework developed within the GRANULAR Horizon Europe project – into an empirical typology of 925 non-urban NUTS3 regions across 26 EU Member States and systematically compares it with DEGURBA. Using principal component analysis and k-means clustering on 15 publicly available indicators spanning residential, productive, environmental, and recreational functionalities, we identify four types of non-urban regions: tourism-depopulation, agricultural-peripheral, forest-environmental, and productive-suburban. The two classifications prove largely non-overlapping: DEGURBA differentiates regions along a density-agriculture gradient, whereas the Compass typology captures environmental structure, landscape composition, demographic trajectory, and tourism specialisation – dimensions on which DEGURBA has negligible discriminatory power. Within DEGURBA's own categories, Compass types reveal substantial heterogeneity, including threefold differences in economic development and 2.5-fold differences in environmental capital among regions sharing the same density-based label. These findings indicate that the two systems address different but complementary questions, arising at successive stages of territorial analysis: DEGURBA defines where rural areas are; the Compass characterises what kind of rural areas they are. Post-2027 EU rural policy – spanning Cohesion Policy, the Common Agricultural Policy, and the European Green Deal – would benefit from adopting a dual-classification approach to territorial targeting and instrument design.
