Since more than 1.8 million lives are estimated to have been lost due to COVID-19 around the world in 2020, research on Life expectancies of nations is being done widely. A recent study published at the International Journal of Epidemiology investigated life expectancy reductions in 2020 against trends in 2015–2019. This was done using demographic data from 29 countries, representing most of Europe, Chile and the USA. Results showed that out of the 29 countries analyzed, the COVID-19 pandemic led to reductions in life expectancy in 27 countries, with large reductions in life expectancy of >1 year in 11 countries for males and 8 among females. Upon comparing against recent trends, females in 15 countries and males in 10 ended up with lower life expectancy at birth in 2020 than in 2015. Interestingly, reductions in life expectancy observed in Central and Eastern European countries in 2020 exceeded those observed around the dissolution of the Eastern Bloc, whereas similar magnitudes of losses in Western Europe were last seen around World War II era.
