The concept of “urban living” encompasses a number of interrelated dimensions, among which: population size and density; spatial, economic and social organisation; the variety of functions and institutional interactions; the social values of the population or degree of “civility” (often also referred to as “urbanism”), etc. In addition, the spread of inter-urban connectivity, that is to say, the growing conurbation effect over the past few decades, has made it necessary to redefine the concept in order to emphasize interactions and functional relations instead of geo-morphological criteria. As reported by Hall (1969, pp. 408-435) and Hart (2003, pp. 102-123), much of the movement that a few decades ago was considered at the regional level is now viewed in terms of growth in urban agglomerations which, in some cases, can even cross national boundaries, as in the case of urban areas between Belgium and The Netherlands or between France, Germany and Switzerland.
