Demographic transition, immigration, gentrification: Unravelling early signs of re-urbanisation in a European city

Population growth and decline have been investigated in the last century adopting multiple qualitative and quantitative approaches, indicators and statistical techniques analysing data on vastly different spatial levels (Frenkel and Kaplan 2014; Haase et al. 2010; Salvati et al. 2016; Van Criekingen 2010). Recent studies have demonstrated a transition towards complex dynamics of urban development, featuring polycentric expansion and spatially heterogeneous population dynamics (Andersen et al. 2011; Arapoglou and Sayas 2009; Catalan` et al. 2008; Cohen 2006). In this framework, advanced and wealthy regions are now undergoing a process of demographic transition which is attracting the attention of many scholars worldwide (Angel et al. 2011).
