Recent works have highlighted how many of the major urban agglomerations in Italy are undergoing a new phase of demographic growth. This could be called reurbanization phase according to the theory of spatial cycles and the underlying model of urban life cycle. The occurrence of this phenomenon in a decade when the foreign resident population has tripled could be not only a coincidence. The primary aim of the article is to evaluate the contribution of internal and international migration to the population dynamics of eight Italian urban agglomerations (Turin, Milan, Verona, Bologna, Florence, Rome, Naples and Palermo) during the period 2001–2010. Secondly, the article analyzes the main demographic features of the foreign resident population in those eight urban settings in order to find potential regularities or discontinuities both across and within (core and rings) the selected urban agglomerations. The demographic censuses as well as administrative data from municipal population registers have been used to compute elementary indicators then synthetized by multidimensional data analysis. The results obtained show that in all the urban agglomerations of the Centre-North the population expansion in the last decade is mostly or entirely driven by the foreign component in the centre and periphery alike. On the contrary, growth in the main urban areas located in the Southern region is stagnant despite the contribution (not as relevant anyway) from the foreign population. Regarding the characteristics of foreign population important differential aspects coming out not only across but also\ud within the same urban agglomerations

Residential segregation is a well studied subject especially after the publication of the pioneering and seminal contribution of Duncan and Duncan (Am Sociol Rev 41:210-217, 1955). Considering the theoretical and methodological advances made since then, the contribution endeavours in describing and understanding the differences in residential segregation in an international perspective using 2011 population census data. The contribution analyses the residential segregation of migrants (here foreign citizens or foreign born) usually resident in the 493 Functional Urban Areas (FUAs) of selected European Union countries. The analysis is conducted using 2011 census data on regular grid (100 mt × 100 mt) provided by the Data Challenge on 'Integration of Migrants in Cities' (D4I) and refers to all migrants and to two sub groups (EU 28 and non EU 28). In a first step the levels and spatial patterns of residential segregation across all FUAs of France,

Density-dependent population growth regulates long-term urban expansion and shapes distinctive socioeconomic trends. Despite a marked heterogeneity in the spatial distribution of the resident population, Mediterranean European countries are considered more homogeneous than countries in other European regions as far as settlement structure and processes of metropolitan growth are concerned. However, rising socioeconomic inequalities among Southern European regions reflect latent demographic and territorial transformations that require further investigation. An integrated assessment of the spatio-temporal distribution of resident populations in more than 1,000 municipalities (1961–2011) was carried out in this study to characterize density-dependent processes of metropolitan growth in Greece. Using geographically weighted regressions, the results of our study identified distinctive local relationships between population density and growth rates over time. Our results demonstrate that demographic growth rates were non-linearly correlated with other variables, such as population density, with positive and negative impacts during the first (1961–1971) and the last (2001–2011) observation decade, respectively. These findings outline a progressive shift over time from density-dependent processes of population growth, reflecting a rapid development of large metropolitan regions (Athens, Thessaloniki) in the 1960s, to density-dependent processes more evident in medium-sized cities and accessible rural regions in the 2000s. Density-independent processes of population growth have been detected in the intermediate study period (1971–2001). This work finally discusses how a long-term analysis of demographic growth, testing for density-dependent mechanisms, may clarify the intrinsic role of population concentration and dispersion in different phases of the metropolitan cycle in Mediterranean Europe.
