A new analysis of decades of U.S. Mortality data reveals a concerning trend: some generations, particularly those born in the late 1960s and early 1970s, are experiencing higher mortality rates than previous cohorts, and are dying from conditions typically associated with older age.
The study, published in the journal Proceedings of the National Academy of Sciences, examined death certificate data from individuals born between the 1890s and the 1980s, spanning the years 1979 through 2023. Researchers, led by Leah Abrams, an assistant professor of community health at Tufts University, analyzed mortality rates across age groups and over time, categorizing deaths by all causes, cardiovascular disease, cancer, and “external causes” – including drug overdoses, suicides, homicides, and accidents.
While U.S. Life expectancy saw significant gains in the 20th century, progress stalled in the 2010s, and remains lower than that of other wealthy nations. The research indicates this stagnation isn’t uniform across generations. The analysis shows that certain birth cohorts are facing worse health outcomes than their predecessors, including an increase in deaths from diseases once considered rare in younger populations.
The study’s findings point to a complex interplay of factors contributing to these trends. Researchers identified rising “deaths of despair” – encompassing drug overdoses, suicides, and alcohol-related deaths – as a significant component. However, the analysis also highlights stalled progress in combating heart disease as a contributing factor, suggesting that no single explanation fully accounts for the observed decline in life expectancy for these specific generations.
The research team’s examination of mortality trends across different causes of death allowed them to determine whether the shortened life expectancy was driven by a single factor or a combination of overlapping crises. The data suggests the latter, with multiple challenges impacting different generations in distinct ways.
According to a report from the World Economic Forum, Generation X, those born between 1965 and 1980, and their families are currently a major driver of consumer spending. This demographic is now entering middle age, a period traditionally associated with increased health concerns and financial responsibilities, potentially exacerbating existing mortality trends.
The study’s findings raise questions about the future of public health in the United States, and the potential for continued declines in life expectancy if current trends persist. Abrams and her colleagues note the importance of understanding these generational differences in mortality to develop targeted interventions and policies to improve health outcomes.
