Unraveling the (Uneven) Linkage? A Reflection on Population Aging and Suburbanization in a Mediterranean Perspective

Abstract

A complex interplay between socioeconomic transformations and demographic dynamics has characterized the long-term development of European countries. As a characteristic example of such linkage, the present study focuses on the spatial relationship between metropolitan growth and population age structure. Preferences for urban and suburban locations reflect complex socioeconomic phenomena such as sprawl, class segregation, gentrification and filtering. However, the spatial linkage between sprawl and demographic transitions was relatively poorly analyzed, and should be more extensively investigated in relation with population dynamics and socioeconomic structures at local scale. By reviewing pertinent literature, this study outlines how space exerts a non-neutral impact on population age structures in Europe, shaping housing needs and influencing settlement patterns and processes of urban transformation. While suburban locations have concentrated younger families and larger households in Northern and Western Europe, the socio-demographic composition of new settlements is increasingly dominated by older inhabitants in the Mediterranean region. Results of this work suggest how discontinuous urban expansion was specifically associated with an elder, wealthy population with high standard of living and a preference for specific housing locations such as detached villas with gardens and swimming pools.
