A progressively ageing population was the landscape that the Covid-19 epidemic encountered when it struck the world in 2020. Given the relationship between Covid-19 and age, it would be logical to deduce that demographic ageing is a sufficient predictor of the impact of this virus on populations. Focusing on European Countries-territory with an exceptionally high population ageing level and where the fatal incidence of the virus has been particularly significant-we conclude that demographic ageing is not a predictor of the impact of this virus on populations. The correlation coefficients, for 2020, between the percentages of people aged 65 or more and the Covid-19 mortality rates per 1 million inhabitants or between the “variation life expectancy at age 65, 2020-2019” and the “percentage of people aged 65 or more” were very weak. Individual age matters for the mortality rate of Covid-19, but population age (inside EU 2020) does not.
