Splintering Urban Populations: Emergent Landscapes of Reurbanisation in Four European Cities

During the last three decades, the countries of the developed world have been engulfed by the 'second demographic transition', which involves new family relations, less and later marriage, declining fertility rates, population ageing, postponement of child-bearing and smaller households, among other trends. It is being increasingly argued that such population dynamics are having a powerful transformative effect on the inner city, by diversifying and redensifying its social landscapes, and creating a 'splintered' urban form. Based on the findings of a recent EU Framework 5 research project, this paper investigates the demographic contingencies of this process-also known as reurbanisation-in four European cities: Leipzig (Germany), Ljubljana (Slovenia), Bologna (Italy) and Leon (Spain). Analyses of census and municipal registry data, as well as on-site questionnaire surveys and interviews, have revealed that the reviewed cities are being populated with, and fragmented by, multiple migration trends and new household structures connected to the second demographic transition.
