Demographic perspectives on the mortality of Covid-19 and other epidemics

‘With a hypothetical 1 million COVID-19 deaths [in the US], it is possible to portray the epidemic as unimaginably large—the biggest killer in American history—or small, reducing our remaining life [expectancy] by less than 1 part in 1,000. However, when the loss of life is put into comparative perspective, we see that the scale of an epidemic with 1 million deaths would be as large as that of the recent opioid and HIV crises but much smaller than that of the Spanish flu. The 1918 epidemic killed more people relative to population size, and it also caused a much greater loss of remaining life expectancy because those who died were so young.

‘As a society, we are and we should be making major and costly efforts to reduce mortality. The anticipated economic costs appear appropriate, or perhaps low, when compared to the statistical value of lives that may be saved.

‘The death toll of COVID-19 is a terrible thing, both for those who lose their lives and for their family, friends, colleagues, and all whom their lives touched. Those are real individuals, not the abstract statistics presented here. But the population perspective helps us to place this tragedy in a broader context. As we put our efforts into reducing the impact of the epidemic, it is important to know that we as a society have been through such mortality crises before.’
