“…Methodologically, proposals have emerged from different disciplinary and institutional areas. Research works typically use statistical repertoires and the territorialization of data [39,40], which are based on three types of indicators: 1. indirect indicators, such as the existence of certain economic activities, the dynamics of population and housing growth, the typology of housing, etc., usually referring to the municipality due to the absence of sources on a lower scale in Spain [41,42]; 2. morphological characteristics, based on the density of the built space, the continuity of the urbanized area or the type of predominant land use, using remote observation techniques, such as Corine Land Cover or Siose, with certain problems in identifying the processes of urban dispersion [6,26,[43][44][45][46][47]; 3. indicators of functional relationships between municipalities, based on commuter mobility between work or study and home [40,[48][49][50][51][52][53]. In almost all cases, municipalities are used as administrative units of reference.…”
