<b>A 1-km resolution dataset of affordability-constrained accessibility to elderly care facilities in China (v1)</b>

This dataset provides a 1-km resolution assessment of accessibility to elderly care services across China, integrating both spatial accessibility and economic affordability dimensions. Accessibility was measured using improved spatial interaction models that account for facility capacity, service competition, and transportation networks, while affordability was incorporated through the ratio of per capita disposable income to care service costs. The dataset captures multi-dimensional disparities in elderly care resource allocation, offering a valuable foundation for aging policy research, spatial equity analysis, and urban–rural planning.
