Educated Americans live longer, as others die younger
(Anne Case and Angus Deaton. “Life expectancy in adulthood is falling for
those without a BA degree, but as educational gaps have widened, racial
gaps have narrowed”. PNAS, 2021. Adaptado.)
A 25-year-old American with a university degree can
expect to live almost a decade longer than a contemporary who
dropped out of high school. Although researchers have long
known that the rich live longer than the poor, this education
gap is less well documented — and is especially marked in
rich countries. And whereas the average American’s expected
span has been flat in recent years — and, strikingly, even
fell between 2015 and 2017 — that of the one-third with a
bachelor’s degree has continued to lengthen.
This disparity in life expectancy is growing, according to
new research published in the Proceedings of the National
Academy of Sciences. Using data from nearly 50m death
certificates filed between 1990 and 2018, Anne Case and
Angus Deaton of Princeton University analysed differences
in life expectancy by sex, race, ethnicity and education. They
found that the lifespans of those with and without a bachelor’s
degree started to diverge in the 1990s and 2000s. This gap grew even wider in the 2010s as the life expectancy of
degree-holders continued to rise while that of other Americans
got shorter.
What is the link between schooling and longevity? Some
argue that better-educated people develop healthier lifestyles:
each additional year of study reduces the chances of being a
smoker and of being overweight. The better-educated earn
more, which in turn is associated with greater health. Ms
Case and Mr Deaton argue that changes in labour markets,
including the rise of automation and increased demand for
highly-educated workers, coupled with the rising costs of
employer-provided health care, have depressed the supply
of well-paid jobs for those without a degree. This may be
contributing to higher rates of alcohol and drug use, suicide
and other “deaths of despair”.
