This document discusses using the capability approach to assess urban quality of life. It first provides background on the capability approach and defines urban quality of life. It then presents a benchmark model for capability approach assessments with requirements like an explicit capability list, a focus on individuals and spatial distribution. Several case studies are reviewed that do and do not explicitly apply the capability approach. Key conclusions note challenges in operationalizing the approach like defining capabilities and collecting appropriate data, but that the capability approach provides a new perspective for urban quality of life research.
