Movilidad residencial intraurbana de los españoles y extranjeros en Zaragoza (España): diferentes espacios, distintos procesos

Residential mobility is a material and symbolic practice that is part of social production in urban space. Physical and social conditions and the representation of the geographic space in which the current and future residents are located are fundamental factors in the decisions that individuals and families make when changing residence. Each social group, differentiated by their nationality, ethnicity, age, or socioeconomic status, appraises the advantages and disadvantages of each location in a different way, and this generates different spatial patterns of residential mobility. We study at various scales the functional and spatial configurations of the changes of residence of a group of Spaniards and foreigners that occurred in the city of Zaragoza (Spain) between 2003 and 2017. This is understood as a relational network of places connected by origin-destination flows of changes of residence. Individual data aggregated in census sections have been used with a methodology that combines spatial analysis procedures and geosocial networks. Results show that the residential mobility networks of both groups have different functional organisations in different spaces. The effects of residential mobility are manifested by variations in the volume of the population and the sociodemographic composition of each area. Finally, the distribution of the distances involved in changes of residence of Spaniards and foreigners was well adjusted to a lognormal model, which enables accurately predicting the location of a residence.
