The document discusses the need for new approaches to mapping, forecasting, and modeling social impact in the housing sector. It notes that traditional social return on investment reporting is no longer sufficient and that a new model is needed to better capture the social value of housing. Specifically, the document proposes using well-being valuation and generating metrics to measure the well-being impact of housing through areas like homeownership, maintenance, and community investment. It aims to further refine these metrics and build tools to apply them to better understand and prove the social value generated by the housing sector.
