Research published this week in the Journal of the
American Medical Association estimated that poverty was linked to at least
183,000 deaths in the United States in 2019 among people aged 15 or older,
making inadequate income the nation's fourth-leading mortality driver that year
behind heart disease, cancer, and smoking.
“Poverty
kills as much as dementia, accidents, stroke, Alzheimer's, and diabetes,"
said David Brady, a professor of public policy at the University of California,
Riverside and the lead author of the new analysis.
"Poverty silently killed 10 times as many people as all
the homicides in 2019," Brady continued. "And yet, homicide,
firearms, and suicide get vastly more attention."
Rev. Dr. William J. Barber II, co-chair of the Poor People's
Campaign, wrote Wednesday that the research underlines the importance
of connecting extremists' inaction on gun violence to other forms of policy
murder.
The new
analysis, co-authored by Ulrich Kohler of the University of Potsdam in Germany
and Hui Zheng of Ohio State University, stressed that the US perennially has a
far higher poverty rate than peer-rich democracies, which presents an enormous
challenge to population health given that considerable research demonstrates
that being in poverty is bad for one's health.
Poverty, which the study defined as less than half the median
US income, was associated with greater mortality than many far more visible
causes in 2019—10 times as many deaths as homicide, 4.7 times as many deaths as
firearms, 3.9 times as many deaths as suicide, and 2.6 times as many deaths as
drug overdose."
The researchers argued their results indicate that poverty
should be considered a major risk factor for death in the US, which has seen
life expectancy decline since 2015—and fall sharply amid the
coronavirus pandemic.
"Because the US consistently has high poverty rates,
these estimates can contribute to understanding why the US has comparatively
lower life expectancy," the researchers wrote. "Because certain
ethnic and racial minority groups are far more likely to be in poverty, our
estimates can improve understanding of ethnic and racial inequalities in life
expectancy."
The mortality associated with poverty is also associated
with enormous economic costs, they continued. Therefore, benefit-cost
calculations of poverty-reducing social policies should incorporate the
benefits of lower mortality. Moreover, poverty likely aggravated the mortality
impact of Covid-19, which occurred after our analyses ended in 2019. Therefore,
one limitation of this study is that our estimates may be conservative about
the number of deaths associated with poverty.
The onset of the coronavirus pandemic in 2020 brought about
a sharp increase in US poverty as millions of people got sick, were
thrown out of work, and lost health insurance.
Federal
aid initiatives enacted in response to the public health and economic
crisis—from stimulus checks to boosted unemployment benefits to enhanced
nutrition assistance—ultimately led to a significant drop in poverty,
further bolstering the case that poverty is a policy choice.
However, many of those poverty-reducing aid programs,
including the enhanced Child Tax Credit that sharply slashed poverty among kids
in the US, have since lapsed or been terminated, threatening to reverse any
recent progress.
Brady said in a statement that if the US had less poverty, there'd
be a lot better health and well-being, people could work more, and they could
be more productive.
"All of those," he added, "are benefits of
investing in people through social policies."
