How large is the mortality gap between college and noncollege Americans?
Core argument: The adult life expectancy gap between Americans with and without a four-year college degree reached 8.5 years by the end of 2021, after widening in each of three periods: 1992–2010, 2010–2019, and the COVID pandemic.
From 1992 to 2010, American adults with and without a four-year college degree saw falling mortality, but with greater improvements for the more educated; from 2010 to 2019, mortality continued to fall for those with a BA while rising for those without; during the COVID pandemic, mortality rose for both groups, but markedly more rapidly for the less educated. In consequence, the mortality gap between the two groups expanded in all three periods, leading to an 8.5-year difference in adult life expectancy by the end of 2021. One remarkable finding here is that Americans with a college degree, if they were a separate country, would be one of the best performers, just below Japan, though there was some decline in 2020 and 2021 during the pandemic.
