The aging population has a tremendous impact on our community and resources. Planning age-friendly cities is a sustainable solution towards healthy aging and health resources allocation. Our research team developed a framework to systematically evaluate the age-friendliness of cities. The framework encompassed multiple criteria and included assessment using web-based Geographical Information System (GIS) tools. We applied our analytical framework to Palo Alto, Stanford as an illustrative case study. The study site was chosen due to its unique characteristics (% seniors is 30% higher than US average, 80% of whom expressed the desire to continue living in this community) and its proximity to us allowing easy site visits and data access. In this paper, we discuss the results of our analyses, as well as our development of an Age-Friendly Cities Scorecard to translate guidelines into tangible and measurable action items.
