Spatial Justice and Hyper-Accessibility for Older Adults: A Comparative Study of Madrid and Munich

Global urbanization and population aging urgently require cities to adapt to support older adults’ independence and well-being. While active mobility drives health and social equity, micro-scale proximity remains under-studied. This study evaluates ‘hyper-accessibility’ to essential daily services for older adults in Madrid and Munich, examining distributive spatial justice and its implications for healthy aging. Using quantitative spatial analysis, walking accessibility to seven key services was modeled at a strict 300 m threshold. These metrics were intersected with a sociodemographic disadvantage score to reveal urban disparities. Key findings expose structural contrasts. In Madrid, 50.82% of older adults achieve hyper-accessibility to daily services, though green areas (8.86%) and health facilities (15.82%) represent critical gaps. Conversely, Munich’s decentralized fabric yields hyper-accessibility for just 31.6% of seniors, with community centers (7.19%) and sports facilities (8.6%) being severely restricted. These spatial inequities highlight how restrictive walking thresholds function as invisible barriers to active mobility, isolating older populations. Ultimately, integrating hyper-accessibility metrics into local planning is vital for mitigating these baseline deficits and fostering age-inclusive, socially just urban environments.
