Ok, how do they know?Covid-19: death rate is 0.66% and increases with age, study estimates
The overall death rate from covid-19 has been estimated at 0.66%, rising sharply to 7.8% in people aged over 80 and declining to 0.0016% in children aged 9 and under.
Never mind, likely garbage-in, garbage-out.The estimates, calculated by researchers in the UK, used aggregate data on cases and deaths in mainland China. Unlike other estimates, however, they adjusted for undiagnosed cases and the number of people in each age group of a population.
