CDC Report Shows Steep Drop in US Life Expectancy in 2020

posted by Jason Kottke   Dec 22, 2021

The CDC recently released their report on Mortality in the United States, 2020 and this graph of US life expectancy at birth since 1950 by Christopher Ingraham dramatically summarizes the report’s main finding:

That’s a decrease in life expectancy of 1.8 years from 2019. Here are some more of the report’s significant findings:

In 2020, life expectancy at birth was 77.0 years for the total U.S. population — a decrease of 1.8 years from 78.8 years in 2019. For males, life expectancy decreased 2.1 years from 76.3 in 2019 to 74.2 in 2020. For females, life expectancy decreased 1.5 years from 81.4 in 2019 to 79.9 in 2020.

In 2020, the difference in life expectancy between females and males was 5.7 years, an increase of 0.6 year from 2019.

The age-adjusted death rate for the total population increased 16.8% from 715.2 per 100,000 standard population in 2019 to 835.4 in 2020. Age-adjusted death rates increased in 2020 from 2019 for all race-ethnicity-sex groups, increasing 42.7% for Hispanic males, 32.4% for Hispanic females, 28.0% for non-Hispanic Black males, 24.9% for non-Hispanic Black females, 13.4% for non-Hispanic White males, and 12.1% for non-Hispanic White females.

In 2020, 9 of the 10 leading causes of death remained the same as in 2019. The top leading cause was heart disease, followed by cancer. COVID-19, newly added as a cause of death in 2020, became the 3rd leading cause of death. Of the remaining leading causes in 2020 (unintentional injuries, stroke, chronic lower respiratory diseases, Alzheimer disease, diabetes, influenza and pneumonia, and kidney disease), 5 causes changed ranks from 2019. Unintentional injuries, the 3rd leading cause in 2019, became the 4th leading cause in 2020. Chronic lower respiratory diseases, the 4th leading cause in 2019, became the 6th. Alzheimer disease, the 6th leading cause in 2019, became the 7th. Diabetes, the 7th leading cause in 2019, became the 8th. Kidney disease, the 8th leading cause in 2019, became the 10th leading cause in 2020. Stroke, and influenza and pneumonia, remained the 5th and 9th leading causes, respectively. Suicide dropped from the list of 10 leading causes in 2020.

And from the report’s summary:

From 2019 to 2020, the age-adjusted death rate for the total population increased 16.8%. This single-year increase is the largest since the first year that annual mortality data for the entire United States became available. The decrease in life expectancy for the total population of 1.8 years from 2019 to 2020 is the largest single-year decrease in more than 75 years.

Since more people in the US died of Covid in 2021 than in 2020, I’d expect the decline life expectancy and the rise in death rate to continue.
