• 600,000 Americans have died of COVID-19 since the coronavirus outbreak began.
  • Researchers have estimated the number of “life years” lost due to COVID-19, a statistic that takes life expectancy into account.
  • On average, COVID-19 deaths caused a loss of 14 life years.
  • The total loss was nearly 5.5 million life years in the U.S in 2020 alone.

About 600,000 Americans have died of COVID-19 since the coronavirus outbreak began. But behind that huge figure is a more nuanced one that brings the human toll of the virus into even sharper relief.

In addition to the overall number of deaths from a given cause, researchers can estimate the number of “life years” lost due to it – a statistic that takes life expectancy into account. For example, if a person with a life expectancy of 80 dies at age 50, they are estimated to have lost 30 years of life. Examining this statistic underscores the extent to which the virus has cut Americans’ lives short.

In 2020 alone, the coronavirus was responsible for about 380,000 deaths and roughly 5.5 million years of lost life in the United States, according to a Pew Research Center analysis of provisional data from the Centers for Disease Control and Prevention. That number of life years lost is more than the number lost in a typical calendar year to all accidents combined – including traffic accidents, drownings, firearm accidents, drug overdoses and other poisonings – and more than triple the number of life years lost in a normal calendar year due to liver disease or diabetes.

(This analysis compares provisional 2020 data for coronavirus deaths with final 2019 data for all other causes of death. We took this approach for several reasons: Only provisional data is currently available for COVID-19 deaths in 2020; detailed provisional data is not currently available for all other causes of death in 2020; and the pandemic affected mortality patterns for non-coronavirus causes in 2020, too. That makes 2019 a suitable comparison point for the typical number of deaths from various causes in a given year. For more about the methodology of this analysis, read “How we did this.”)

The same figures reveal that the average number of life years lost per U.S. coronavirus death in 2020 was 14 years. This is comparable to the average number of years lost per heart disease death in the U.S. in 2019 (13 years) and somewhat lower than the average number of years lost per cancer or diabetes death that year (17 years). But it is far below the average number of years lost per liver disease (24 years) or accidental death (31 years).

Life expectancy increases with age

The large number of life years lost due to COVID-19 in 2020 may not be widely appreciated because people ages 65 and older account for a large majority (approximately 80%) of U.S. coronavirus deaths to date. Some observers have raised the point that the public may believe that these older Americans were nearing the end of their lives anyway.

What is the World Economic Forum doing about the coronavirus outbreak?

Responding to the COVID-19 pandemic requires global cooperation among governments, international organizations and the business community, which is at the centre of the World Economic Forum’s mission as the International Organization for Public-Private Cooperation.

Since its launch on 11 March, the Forum’s COVID Action Platform has brought together 1,667 stakeholders from 1,106 businesses and organizations to mitigate the risk and impact of the unprecedented global health emergency that is COVID-19.

The platform is created with the support of the World Health Organization and is open to all businesses and industry groups, as well as other stakeholders, aiming to integrate and inform joint action.

As an organization, the Forum has a track record of supporting efforts to contain epidemics. In 2017, at our Annual Meeting, the Coalition for Epidemic Preparedness Innovations (CEPI) was launched – bringing together experts from government, business, health, academia and civil society to accelerate the development of vaccines. CEPI is currently supporting the race to develop a vaccine against this strand of the coronavirus.

But life expectancy statistics tell a different story. In fact, life expectancy increases with age. While babies born in the U.S. today can expect to live to be 79, Americans who are 65 today can expect to live to 85, according to the United Nations World Population Prospects. Current 80-year-olds, in turn, can expect to live to an average age of 90.

The pandemic, in other words, has killed many Americans who otherwise might have expected to live for years or even decades longer. A 65-year-old who dies from COVID-19 might ordinarily have expected to live until 85 – a difference of two decades, or roughly a quarter of the average American’s total expected life span at birth.

Average life spans change with age as common causes of death shift over time. By the time a U.S. adult lives to 65, they are unlikely to die from some common causes of death among younger people, such as homicide, pregnancy complications or congenital diseases. At the same time, older Americans are more likely than their younger counterparts to die from causes including heart disease, Alzheimer’s – and now COVID-19.
