Investments with returns: a systematic literature review of health-focused housing interventions

Housing access and the built environment are both recognized as significant social determinants of health. Numerous studies and articles detail housing-based interventions that result in improved health outcomes. However, less is known about potential financial impacts and which programs and initiatives not only improve health but also generate return on investment (ROI). Through a systematic literature review, the authors identified evidence regarding the economic benefits of housing interventions aimed at improving health, using ROI as a measure of program success. Specifically, housing interventions that are aimed at childhood asthma, HIV, chronic illness among the homeless, and urban blight have demonstrated a positive ROI ranging from 30 to 480%, with most cost savings attributed to meaningful reductions in hospitalizations and emergency department visits.
