What this new edition of State of the World’s Cities shows is that prosperity for all has been compromised by a narrow focus on economic growth. UN-Habitat suggests a fresh approach to prosperity beyond the solely economic emphasis, including other vital dimensions such as quality of life, adequate infrastructures, equity and environmental sustainability. The Report proposes a new tool – the City Prosperity Index – together with a conceptual matrix, the Wheel of Prosperity, both of which are meant to assist decision makers to design clear policy interventions.
