From South Asia to Southern Europe: a comparative analysis of Sri Lankans’ residential segregation in the main Italian cities using high-resolution data on regular lattice geographies

The present work proposes a spatial analysis of the residential segregation and settlement models of Sri Lankans in the eight main Italian municipalities. Hosting more than half of the total Sri Lankan population residing in Italy, the selected urban areas allow Sri Lankans’ residential model to be globally framed across the country. The purpose of this work is threefold. First, it provides a general assessment of the allocation pattern of a foreign community that has seldom been studied and yet is characterized by peculiar settlement choices. Second, it attempts to compare the settlement patterns of Sri Lankans across different urban contexts. Third, it aims to detect the possible spatial polarization of Sri Lankans in specific neighbourhoods and to verify its spatial correlation with other key variables that constitute proxies of urban neighbourhoods’ socioeconomic inequalities. The study runs multiple aspatial linear models to assess the global variation in concentrations of Sri Lankans related to several socioeconomic predictors. Furthermore, it implements geographically weighted regressions to explicitly model the spatial dependence between Sri Lankans’ location quotients and several predictors. It refers all the considered variables to a single geographic reference grid, enabling the homogenization of different areal unit arrangements and comparisons across space. Except for Milan and Rome, the findings suggest that Sri Lankans tend to reside in central neighbourhoods characterized by a high foreign presence and a decreased trend of Italian population. Conversely, the impact of the cost of living and the state of the built environment is heterogeneous across space, with a sort of centre-periphery duality in Southern cities and more fragmented situations in the other urban contexts. This evidence proves the relevance of local scale analysis and the need to build up urban observatories on spatial inequalities and segregation processes.
