It’s clear that 2020 was a terrible year for health in the U.S., but just how terrible is now coming into focus. New mortality data from the National Center for Health Statistics finds that life expectancy dropped by 1.8 years in 2020 compared to 2019, and more than 528,800 more U.S. residents died in 2020 than in 2019. It is the largest single-year increase in annual mortality since 1933, when data for the entire country first became available.

COVID-19 is the primary reason for this shift.
