U.S. deaths from COVID-19 are leading to a more than a year-over decline in life expectancy

According to a study conducted by researchers from the University of Southern California (USC) and Princeton University, COVID-19-induced deaths have reduced overall life expectancy in the United States by 1.13 years. Epidemiologically, this is a major recession. Life expectancy is one of the most accurate bars in society’s health.

Adding to the pandemic of the pandemic, a new variant of the coronavirus has been discovered across more than 12 states, threatening to exacerbate the crisis.

On New Year’s Day, the U.S. had recorded 20.7 million cases of COVID-19 and nearly 357,000 deaths, making it the third leading cause of death behind cancer and heart disease. However, this retention figure represents only confirmed cases.

In total, the U.S. Centers for Disease Control and Prevention (CDC) detected more than 475,000 premature deaths in early December. It is estimated that nearly two-thirds of overweight deaths are directly attributed to COVID-19. Compared to 2019, deaths in the U.S. have climbed more than 10 percent.

The term “life expectancy” is often used in epidemiology to assess the health of a nation but allows comparisons to be made between countries and groups of people. In the simplest sentence, it is an estimate of the average age of people in a particular population when they die.

The most common metric used by international organizations such as the United Nations and the World Bank, also known as the “life expectancy,” is the average life expectancy estimated for a given population from birth to death. It does not take into account how mortality rates change over time. Instead, it focuses on one-time mortality patterns.
