ABSTRACT
El subarriendo de habitaciones es una realidad ampliamente extendida en las grandes áreas urbanas;sin embargo, la ausencia de estadísticas al respecto dificulta su análisis. Gran parte de la población inmigrante accede a una vivienda mediante esta modalidad. Por ello, en este estudio se analizan 27 entrevistas semiestructuradas para evaluar el papel del subarriendo en la trayectoria residencial de dicho colectivo en el Área Metropolitana de Barcelona. Los resultados confirman la creciente dificultad que tienen los inmigrantes que han llegado recientemente para avanzar en la escala habitacional y, más concretamente, el protagonismo del subarriendo como recurso residencial precario de dicha población, en particular en las etapas tempranas de inserción residencial, aunque no exclusivamente, pues también se ha detectado la existencia de trayectorias residenciales inversas. Se comprueba también la presencia de submercados de habitaciones a los que se accede de manera exclusiva a través de cadenas migratorias.Alternate :The subleasing of rooms is a widespread reality in large urban areas, however, the absence of statistics in this regard makes its analysis difficult. A large part of the immigrant population has access to a dwelling through this modality. Therefore, in this study, 27 semi-structured interviews are analyzed to evaluate the role of subleasing in the housing patterns of this group in the Metropolitan Area of Barcelona. The results confirm the increasing difficulty that recent immigrants have to advance in the housing scale and, more specifically, the prominence of subleasing as a precarious residential resource for the population, particularly in the early stages of residential insertion, although not exclusively, since the existence of reverse residential trajectories has also been detected. We also verify that the presence of submarkets rooms that are accessed exclusively through migratory chains.
ABSTRACT
This article aims to address the apparent contradiction between the urban demographic and migratory trends and the transition towards a more sustainable mobility that local and metropolitan governments seek. To that end, it uses the case of Barcelona, and its metropolitan area during the first decades of the 21st century, characterized by suburbanisation and gentrification. Employing demographic, mobility and transport, and air quality statistics, we intend to analyse: (a) the spatial demographic trends in the metropolitan area of Barcelona (AMB), particularly regarding the core and periphery population growth or decline;(b) trends in daily mobility and how the public and private transport mix has changed;and (c) pollution data changes confirming the success or failure of the private vehicle reduction policy. Findings confirm our initial hypothesis: the slow but steady transition towards sustainable forms of mobility in the core city and the dense contiguous municipalities is counterbalanced by what occurs in the peripheral suburbs. There, the use of private vehicles is still preeminent and growing. Nevertheless, the air quality has improved in the most central municipalities of the AMB (for which data are available), even if not all parameters have seen a similar pollution reduction.
