El principal colectivo de origen inmigrante en el Área Metropolitana de Barcelona es el latinoa- mericano. Geográficamente, su inserción territorial se caracteriza por la existencia de bajos nive- les de segregación residencial, aunque se observan algunos espacios de concentración localizados preferentemente en los municipios de la primera corona metropolitana. Este trabajo tiene por ob- jetivo caracterizar sociodemográficamente a los latinoamericanos que residen en concentración; y analizar el efecto de las migraciones internas en la conformación de estos espacios. Se trabaja a escala inframunicipal utilizando como fuente principal el Censo de Población y Viviendas de 2011. Los resultados alcanzados revelan una asociación entre las características sociodemográ- ficas de los individuos y su lugar de residencia. Estos mismos espacios se construyen sobre la base de la movilidad interna, dominandolos desplazamientos del centro de la ciudad a la primera corona metropolitana. En cambio, se identifican espacios de concentración media en el casco histórico de Barcelona donde domina el peso de la inmigración del extranjero.

El artículo analiza las pautas residenciales y migratorias de la población de origen latinoamericano durante el período 2000-2017 en las áreas urbanas funcionales de Barcelona y Madrid, divididas en coronas de municipios en función de la distancia a la ciudad central. Utilizando datos del Padrón continuo y de la Estadística de variaciones residenciales (INE), la investigación estudia cómo responden estos fenómenos a las variaciones del ciclo económico, por eso se divide el período en tres fases desiguales: expansión económica (2000-2008), crisis (2009-2014) y poscrisis (2015-2017). Los resultados muestran que la tendencia hacia la suburbanización de esta población en ambas áreas urbanas durante la fase de crecimiento económico se frenó con la crisis, pero que se ha reactivado durante la poscrisis; y que, sin embargo, hay un aumento de su concentración en ambas ciudades centrales en los últimos años, debido a la reactivación de la inmigración latinoamericana.

Spanish functional urban areas have grown rapidly demographically over the last decades. However, age differences within them, between inner cities, with an older population, and their suburban peripheries, with a younger one, have increased. Nevertheless, this urban segregation pattern by age shows variations in different large Spanish urban areas. Our initial hypothesis is that age segregation is greater in large urban agglomerations, and less relevant in smaller urban areas, where age groups are spatially more mixed. The objective of this paper –using official population data on January 1, 2016, at the census tract level– is to analyze this ‘Geography of urban aging and rejuvenation’ and verify if the spatial patterns found are common to the five largest Spanish metropolitan areas : Madrid, Barcelona, Valencia, Seville, and Bilbao. The results show that urban segregation by age does not depend as much on the size of the urban area as on its monocentric nature –percentage of the FUA’s population living in its main city– and above all, on the intensity of suburbanisation.

The paper aims to analyse how the different economic phases that Spain has experienced in the first two decades of the 21st century (expansion, recession, and recovery) have influenced population stocks and migratory flows in the five largest metropolitan areas defined as Functional Urban Areas (FUAs) in Spain: Barcelona, Bilbao, Madrid, Seville and Valencia. Using Padrón Continuo (municipal registers) and Estadística de Variaciones Residenciales (residential change statistics) as data sources, both native and immigrant – i.e. born abroad – stocks, and internal and international migration flows are analysed. We study differences between (a) diverse groups of foreigners (by continental origin), also comparing them to natives; and (b) different types of residential mobility by migrants’ previous place of residence: “intrametropolitan” movements (between urban cores and peripheries), migration flows between the five urban areas and the rest of Spain, and international migration. Results show that intrametropolitan migration flows between the five urban cores and their peripheries were characterised by suburbanisation during the expansion phase. These flows were particularly relevant for Spanish-born persons and, among foreign-born migrants, for people born in the Americas (mainly Latin Americans). These flows to the suburban periphery decreased during the economic crisis, and in 2013 and 2014 net intrametropolitan migration of most foreign groups was characterised by recentralisation. Spaniards’ intrametropolitan movements almost reached equilibrium during the recession years: Natives decreased their moves from cores to rings, while they were increasingly attracted to urban centres. Owing to the incipient economic recovery, suburbanisation is progressively recovering its previous strength. As for other types of residential moves, foreign-born migrants moving from abroad and the rest of Spain to the five FUAs during the economic expansion phase reversed the direction of their flows in the economic crisis years, migrating abroad or dispersing throughout Spain in search of jobs. Consequently, their stocks declined in some years. Currently, due to the incipient economic recovery, the five FUAs are attracting internal and international foreign-born immigrants once again, so their foreign-born population stocks are increasing in both cores and peripheries. Spaniards show the opposite behaviour regarding flows to and from the five areas analysed – they tended to disperse throughout the rest of Spain during the economic expansion phase. This trend continued during the crisis years, but at a slower pace, as natives became increasingly attracted to urban cores. Furthermore, this latter trend has strengthened during the post-crisis years. Finally, considering foreign-born and Spanish populations together, large urban areas are increasingly attractive. This global tendency is to the detriment of rural areas and of non-metropolitan small and medium size towns, which lose population due to negative net migration. * This article belongs to a special issue on “Internal Migration as a Driver of Regional Population Change in Europe: Updating Ravenstein”.
