Housing interventions at the neighborhood level and health: a review of the evidence

Abstract

A panel of subject matter experts systematically reviewed evidence linking neighborhood-level housing interventions, such as housing programs or policies, to health outcomes. One of the 10 interventions reviewed--the Housing Choice Voucher Program--had sufficient evidence for implementation or expansion. The evidence showed that voucher holders are less likely to suffer from overcrowding, malnutrition due to food insecurity, and concentrated neighborhood poverty than non-voucher holders. Of the other reviewed interventions, 2 needed more field evaluation and 7 needed more formative research. None were determined to be ineffective. Although many of the reviewed interventions lacked sufficient evidence for widespread implementation solely based on their health benefits, this evidence review shows that many interventions positively affect other areas of social, economic, and environmental well-being. Efforts to improve neighborhood environments and to maintain and increase the number of affordable housing units are critical to ensuring safe, healthy, and affordable housing for all people in the United States. Given that people of color disproportionately reside in high-poverty neighborhoods, neighborhood-level interventions may be particularly important in efforts to eliminate health disparities.
