The safe, secure, affordable housing provides a foundation that allows individuals, families, and communities to thrive. While there are multiple mechanisms to encourage the production and preservation of affordable housing, a robust body of evidence supports the positive impact that affordable housing can have on economic security, educational attainment, the overall quality of neighborhoods, and job development. A newer area of research has focused on the linkages between affordable housing and health behaviors and outcomes. The evidence is building that housing affordability, neighborhood conditions, and conditions within the home are all important determinants of health. The Low-Income Housing Tax Credit has helped finance millions of affordable homes for low-income individuals across the country, and it has also benefited local economies. While limited data directly connects the LIHTC to positive health outcomes for residents, the robust evidence base linking affordable housing to better health outcomes, and possibly lower costs, makes it reasonable to believe that the LIHTC contributes positively to the nation’s public health.
