In recent years life expectancy has stagnated in the United States, followed by three consecutive years of decline. The decline is small in absolute terms, but is unprecedented and has generated considerable research interest and theorizing about potential causes. Recent trends show the decline has affected nearly all race-ethnic and gender groups, and the proximate causes of the decline are increases in opioid overdose deaths, suicide, homicide, and Alzheimer’s disease. A slowdown in the long-term decline in mortality from cardiovascular diseases has also prevented life expectancy from further improvements. Although a popular explanation for the decline is the cumulative decline in living standards across generations, recent trends suggest that distinct mechanisms for specific causes of death are more plausible explanations. Interventions to stem the increase in overdose deaths, reduce access to mechanisms that contribute to violent deaths, and decrease cardiovascular risk over the life course are urgently needed to improve mortality in the United States.
