A survey found that over 70% of local health officials and 60% of mayors reported abandoning or delaying local policymaking efforts because of the threat of state preemption. Local policies chilled by the threat of preemption included efforts to regulate commercial tobacco, environmental hazards, firearms, minimum wage, safe housing, and transportation, among others.

Research shows that the misuse of state preemption often blocks policies that promote health and equity, with severe – and preventable – consequences such as lower life expectancy, increased infant mortality, and worse overall health outcomes.

State preemption has kept local governments from enacting laws to improve public health, such as regulating the sale of commercial tobacco and alcohol, promoting healthy eating, and enacting gun safety regulations, as well as local laws that address social determinants of health such as economic security, access to safe, stable, and affordable housing, anti-discrimination protections, and access to quality education.

A paper examined the critical role grassroots organizations play in fostering equitable political processes and supporting housing policies that may reduce health inequities. The study found that state preemption often forces such organizations to narrow their policy goals and adapt their political strategies, which then stretches their capacity and limits their ability to be successful. The study concluded that state preemption may therefore cement inequitable housing policies by weakening the political capacity of grassroots organizations that are critical to building power in racially and economically marginalized communities.

A study showed that the more politically conservative a state legislature is, the more likely it is that the state will preempt local affordable housing policies. The same study found that it is less likely for states with more professional legislatures and those with a higher proportion of renters to preempt affordable housing policies. Accordingly, it may be helpful to consider these factors when organizing campaigns to address preemption of affordable housing policies. Read more from Christopher B. Goodman & Megan E. Hatch, State Preemption and Affordable Housing Policy, 49 Publius: J. Fed. (2023).

Austin, Texas, sought to address racial and socioeconomic discrimination in rental housing by prohibiting landlords from rejecting otherwise qualified tenants based solely on their source of income (e.g., federal housing assistance). Across the country, only one in three voucher households is protected by nondiscrimination laws like those Austin adopted. The Texas state legislature responded by invalidating Austin’s ordinance and preempting localities from adopting similar antidiscrimination laws, despite the absence of any statewide protections for recipients of housing assistance and despite clear evidence that source-of-income discrimination disproportionately harms people of color.

A study suggests a relationship between state preemption of local mandatory inclusionary zoning (IZ) policies and both increased rates of self-reported poor or fair health status and a greater likelihood that Black adults report delaying medical care because of cost.

Various studies have concluded that universal basic income (UBI) programs contribute to improved financial well-being, increased savings, and the ability to control daily finances. These studies have also shown that UBI programs can lead to improved housing conditions, increased food security, and even additional employment opportunities. State preemption of UBI programs, therefore, deprives local governments of an important policy shown to improve people’s economic and overall well-being.

When a worker without paid leave must miss work because of their own illness or caregiving responsibilities, two days of lost wages equate to a month’s worth of gas, three days equal a monthly utility payment, and roughly a week of lost wages equals an entire month’s rent or mortgage payment. State preemption of local paid leave laws prevents local governments from addressing these economic injustices. Read more from  Gould E, Schieder, J. Work sick or lose pay?

A large portion of those without paid sick leave are low-wage, part-time workers who are disproportionately Hispanic, Black Americans, and women, meaning state preemption that prevents cities and counties from adopting paid leave laws adds to racial and socioeconomic inequities.

Research finds that laws mandating universal paid leave reduce racial disparities, increase economic security, and improve health outcomes, including reduced emergency department use, increased use of preventive care, and fewer occupational injuries. The same research did not find evidence that paid leave laws reduce employment, wages, or labor force participation. Read more from Marotta, J, Greene, S.

One study found statistically significant associations between paid-sick leave requirements and reductions in homicides (in men and women), suicides (in men), and alcohol poisoning (in women). If state laws preempting paid-sick leave protections were repealed, mortality by these causes may decline by more than 5% in some places. Read more from Wolf DA, Montez JK, Monnat SM.

A report examining minimum wage laws found that state preemption of previously enacted minimum wage laws in 12 cities and counties affected nearly 346,000 workers and resulted in nearly $1.5 billion of lost income per year. These preemption laws disproportionately harmed women, people of color, and communities with high rates of poverty.  Read more from Laura Huizar and Yannet Lathrop.

A study assessing how preemption affects birth outcomes – a key indicator of population health – found that state preemption of local minimum wage laws accounted for as much as 3.5% of infant deaths, resulting in more than 600 infant deaths in 2018 alone. The same study also found that the largest metro counties could reduce the infant mortality rate by 1.5 to 1.8% by increasing the minimum wage by one dollar.
