JHSB Policy Brief: Low-Density Zoning and Health Disparities in Metro Areas.

The article examines how the prevalence of low-density zoning—zoning laws that restrict housing density, such as prohibiting apartment buildings—relates to health disparities in 44 large U.S. cities. It finds that cities with more low-density zoning tend to have wider disparities in self-reported poor health among Black, Hispanic, and low-income populations compared to White and higher-income groups. However, disparities in obesity show mixed results, with income and ethnicity differences unaffected by zoning, while racial disparities in obesity narrow in cities with more low-density zoning. The study suggests that zoning policies influence health equity and that increasing housing density ("up-zoning") in health-promoting, mixed-use communities may help reduce disparities, though local conditions and community engagement are crucial for effective policy.
