Abstract
The immigration of foreign retirees to Spain's southeast coast is a tradition that stretches back decades. This phenomenon has modified the demographic structure of many towns and also transformed their social and economic features, as well as the number and diversity of services available to the population. This study examines the effect of post-employment immigration on economic revitalisation, the increase in services and the arrival of new inhabitants. It demonstrates the transformative potential of the phenomenon for pre-coastal areas in the Spanish southeast and its influence on the configuration of friendly residential environments. The study analyses the evolution of basic demographic data and its spatial behaviour, establishing relationships between the quality of life of the local aging population and retired immigrants. The analysis focuses on the impact of residentialist areas on the configuration of friendly living environments. The results show how these communities, which were once somewhat stagnant and had a significantly aging population, either participated in the development or have improved their access to certain services and facilities, configuring new environments. The results reflect the improvement of the quality of life for the elderly in these settings, considering that they are often the majority age group.
