Gen X and Millennials Face Alarming Rise in Early Deaths

A Generational Health Crisis Emerges

A groundbreaking study has revealed a troubling reality: Americans born between 1970 and 1985 are dying at higher rates than previous generations, marking what researchers call a "turning point" in U.S. life expectancy. This generation—late Gen Xers and elder Millennials—is experiencing worse mortality rates across multiple causes of death, including cardiovascular disease, cancer (especially colon cancer), and external causes like drug overdoses and accidents .

The findings, published in the Proceedings of the National Academy of Sciences, challenge assumptions about American health progress. What stands out is that being born in the 1950s – the middle of the Baby Boomer generation – marks a turning point: from steadily decreasing mortality rates and better health outcomes compared with earlier groups, to the opposite . Before the 1950-1959 birth cohort, each successive generation seemed to have lower mortality than the one before it. This group has experienced worse outcomes than the generations before them, and the generations that followed had mortality improvements that weren't as strong as prior generations .

The increase in deaths among those born from 1970 to 1985 is particularly concerning because cancer and cardiovascular disease tend to be relatively rare in individuals in their 30s and 40s. If these cohorts are showing worse mortality trends already, what's going to happen when they're in their 60s if nothing gets turned around?

The Surprising Cancer Connection

The most surprising finding was the rise in colon cancer deaths among younger generations. There has been a lot in the news these past few years about people younger than 50 increasingly being diagnosed with colon cancer . However, this study goes beyond diagnoses to reveal actual mortality increases, which researchers describe as "genuinely alarming."

Greater cancer prevalence can indicate that we're simply catching cancer sooner through increased screening. But this study shows increased mortality, and it's never good to have more deaths at young ages. This is a genuinely alarming trend . Even though life expectancy was stagnant, cancer mortality had been improving, until researchers found sudden upticks in some types of cancer mortality, especially in those born after 1970. But even in the 1950 and 1960s cohort, they started seeing these sorts of upticks for certain cancers, colon cancer being one of them .

Beyond Drug Overdoses: A Complex Picture

For years, many assumed that drug overdoses in midlife explained stalled U.S. life expectancy. But the findings show that the problem is much broader . The 2010s was a bad decade for mortality across ages. There's a clear period pattern, but it's not just due to deaths from drug overdoses. It's also due to suicides, homicides, traffic accidents, and cardiovascular disease .

External causes include drug overdoses, traffic accidents, homicides, and suicides , but researchers believe these deaths are connected to broader societal pressures. That pattern points to deeper, systemic forces shaping health. The study discusses social and economic conditions that could result in significant stress. Stress is bad for heart disease and can result in drug use. If people feel they can't make it economically or lack social institutions or communities to support them, and their life becomes stressful, that can affect all these causes of death .

Hope Through Historical Precedent

Despite the alarming trends, researchers point to successful public health interventions from the past. The way that tobacco control measures led to a significant drop in deaths from cancer and cardiovascular disease shows these public health wins are possible and can turn around the outlook for future generations . Reductions in mortality resulted from tobacco control, with deaths from cancer overall, lung cancer specifically, and cardiovascular disease all declining from reductions in smoking across subsequent cohorts. That was a huge public health win. Deaths from cardiovascular disease also previously saw significant decreases as a result of improved diet and medical advances .

Prior evidence, combined with these findings, shows that we really need to think holistically if we are to improve U.S. life expectancy. Reducing social inequalities and improving resources for socioeconomically disadvantaged groups could help lessen stress and its harmful effects on health, improve dietary behavior, and reduce substance use . The research suggests that addressing the root causes of stress and inequality may be key to reversing these troubling mortality trends before they worsen as these generations age.
