According to an analysis conducted by researchers from the University of Southern California (USC) and Princeton University, deaths caused by COVID-19 have reduced the overall life expectancy in the United States by 1.13 years. In epidemiologic terms, this is an enormous decline. Life expectancy is one of the most accurate barometers of the health of a society. Since 1860, when life expectancy stood at a stark 39.4 years, predominately due to high infant and maternal mortality, medical advancements and improvements in living standards have seen it climb steadily over the intervening decades to 78.9 years by 2020. Deaths from the COVID pandemic have now further reduced life expectancy to 77.48 years.
