US Death Rates Keep Climbing Above Peer Nations, Study Finds

The United States has spent decades falling behind its economic peers on the most fundamental measure of national well-being: staying alive. A new analysis published in The Milbank Quarterly confirms that mortality rates in the United States have exceeded those of comparable high-income countries for decades, and that the gap is not merely persisting but widening across a broad range of causes of death. The study, led by corresponding author Steven Woolf, MD, MPH, of Virginia Commonwealth University, examines the trajectory of US life expectancy and mortality and finds a crisis that is deeper, older, and more diffuse than the headline epidemics that usually dominate public attention.

The most striking finding is the sheer breadth of the deterioration. Public discussion of American mortality has often centered on the so-called diseases of despair—drug overdoses, suicides, and alcohol-related deaths—that surged in the early twenty-first century. The new analysis shows that external causes remain a major driver of excess deaths, but they are no longer the whole story, and arguably no longer even the largest part of it. Mortality from hypertensive diseases, liver disease, endocrine disorders, and neurologic conditions has also been rising, alongside increases in numerous other categories of illness that were once considered manageable in a wealthy health system.

This shift matters because it changes the kind of explanation that can plausibly account for the trend. An epidemic of overdoses can be traced to the pharmaceutical supply, prescribing practices, and the illicit drug market. A wave of suicides invites attention to mental health services and economic dislocation. But rising death rates from hypertension, diabetes-related endocrine disease, and chronic liver disease point to something more systemic: the slow accumulation of untreated or poorly managed chronic illness across an entire population. These are conditions that develop over years and decades, shaped by diet, access to primary care, insurance coverage, medication adherence, and the environments in which people live and work.

The demographic and geographic patterns identified in the study are equally consequential. Young adults emerge as a particularly affected group, a finding with sobering implications because deaths at younger ages subtract more years of life expectancy than deaths among the elderly. A country whose young and middle-aged adults are dying at rates higher than those of their parents’ generation in peer nations is experiencing a failure that compounds over time, affecting workforce participation, family formation, and the long-term fiscal health of social programs.

Geography adds a second layer of inequality. The analysis highlights that certain regions of the country—most notably the Deep South and Appalachia, as well as rural communities more broadly—carry substantially higher mortality rates than other areas. This regional clustering suggests that state-level policies may be part of the explanation. States differ widely in Medicaid expansion decisions, public health funding, tobacco and alcohol regulation, gun policy, education investment, and the social safety net. Where those policies diverge, so do survival rates. The result is a patchwork nation in which an American’s life expectancy can depend heavily on the state line they happen to live on, a pattern that has no real parallel among peer countries with uniform national health systems.

The COVID-19 pandemic, the study notes, added substantially to the excess death toll, and the United States fared worse than most peer nations during the crisis. But the pandemic is best understood as an accelerant rather than the origin of the problem. Non-COVID causes of death continued to claim lives even as the pandemic waned, and the underlying mortality disadvantage that existed before 2020 has not disappeared. In several peer countries, life expectancy has rebounded toward or beyond pre-pandemic levels; the United States has struggled to recover ground it had already lost decades earlier.

The authors frame the potential contributors as a set of interlocking systems rather than a single culprit. Health care factors include access, affordability, quality, and the well-documented fragmentation of American medical care. Individual behaviors—smoking, diet, physical activity, substance use—are themselves shaped by the environments and economic conditions people face. Income inequality, the physical and social environment, and broader public policies and social values all appear in the analysis as plausible systemic drivers. This framing resists the temptation to blame the crisis on any one cause, and instead points to the cumulative effect of a society that invests less in the upstream conditions that keep people healthy.

The international comparison is what gives the findings their force. Other wealthy democracies that started from similar positions in the mid-twentieth century have achieved steady declines in cardiovascular mortality, better control of chronic disease, and lower rates of death from external causes. The techniques are not mysterious: universal or near-universal insurance coverage, strong primary care, aggressive management of blood pressure and blood sugar, regulation of hazardous products, and social policies that reduce poverty and its health consequences. The study’s central message is that the United States is not failing for lack of knowledge about what works.

That message is captured in the corresponding author’s blunt assessment. “We know how to solve this. Other countries that have outperformed the United States for decades have demonstrated that better health outcomes are possible,” said Woolf. “What we lack in the United States is not solutions but political will.” The statement reframes the mortality crisis from a technical problem awaiting discovery into a political problem awaiting action, a distinction with significant implications for how the findings are likely to be received in policy debates.

Published continuously since 1923, The Milbank Quarterly is a multidisciplinary journal of population health and health policy, and the analysis fits squarely within its tradition of examining the social origins of health. For readers, the takeaway is stark: the divergence between American and peer-country mortality is not a temporary anomaly or the product of a single epidemic, but a long-building, multi-causal crisis that now touches nearly every major category of death and every region of the country. Reversing it, the evidence suggests, will require the same comprehensive approach that peer nations have taken—treating mortality as the ultimate output of health care, policy, and social conditions alike, and measuring national success not only by economic growth but by how long, and how well, citizens live.
