"For a person who is middle-aged, the risk of dying from COVID-19 is about 100 times greater than dying from an automobile accident," explains lead author Andrew Levin, a professor of economics at Dartmouth College. "Generally speaking, very few children and young adults die of COVID-19. However, the risk is progressively greater for middle-aged and older adults. The odds that an infection becomes fatal is only 1:10,000 at age 25, whereas those odds are roughly 1:100 at age 60, 1:40 at age 70, and 1:10 at age 80."

These findings represent the culmination of a systematic review of all available studies of COVID-19 prevalence in countries with advanced economies; this review encompassed more than 1,000 research papers and government documents disseminated prior to September 18, 2020. The research team identified 27 studies where the survey design was representative of the general population, covering 34 geographical locations in the U.S., Canada, Asia, and Europe. Using those prevalence data, the researchers investigated the age-specific ratio of COVID-19 fatalities to infections and found a very clear exponential relationship.
