While some countries have a higher excess mortality rate than the US, it is nowhere close to being the lowest in the world.
During the presidential debate on Oct 22, President Trump claimed that the US excess mortality was lower than most countries in the world. The Centers for Disease Control and Prevention defines excess death as the difference between the observed numbers of deaths in specific periods and expected numbers of deaths in the same time periods. Experts say one of the most telling measures is how many extra deaths a country experiences above the number who would have been expected to die. The excess death rate captures some potentially unrecorded coronavirus deaths and other deaths that might be the indirect result of the pandemic and hence provides a more comprehensive picture.
According to the, overall, an estimated 299,028 excess deaths occurred from late January through October 3, 2020, with 198,081 (66%) excess deaths attributed to COVID-19.
A study conducted by the Journal of the American Medical Association analyzed COVID-19 deaths and excess all-cause mortality in the United States and 18 other developed countries in 2020. found out that the US had a significantly higher excess mortality than many countries. "Compared with other countries, the US experienced high COVID-19–associated mortality and excess all-cause mortality into September 2020. After the first peak in early spring, US death rates from COVID-19 and all causes remained higher than even countries with high COVID-19 mortality," the study said.
