Abstract

Although previous studies have examined the spatial distribution of the aging population in various regions of the world, a significant knowledge gap remains regarding South America. This research aims to address the accelerated demographic change towards an older urban population in cities that have not been planned for this shift and have not developed adaptive urban planning strategies. Socioeconomic and spatial typologies that influence urban aging trajectories in Santiago, Chile, were identified using three methods: geospatial analysis, a data panel, and k-means clustering analysis. It was found that there is a shift in the areas of concentration of older adults, from central to peripheral communes, and that variables such as single-parent families, population density, and high educational levels are factors that increase the concentration of older adults at a communal level. In contrast, homeownership has a negative influence. © (2025) (Universidad del Bío Bío) All rights reserved.
