This paper studies the relationship between Youthfulness and COVID-19 using a wide sample of countries around the world. It utilizes the new Generalized Extreme Value (GEV) estimation technique to analyze the effect of being young on the probability of high COVID-19 modeled as a rare event. The results illustrate that an increase in young people in a country reduces the probability of high COVID-19. The empirical findings also show how numerous other Bio-SocioEconomic variables affect the probability of high COVID-19. The negative impact of Youthfulness on the probability of high COVID-19 is maintained when we control for subsamples of Least Developed Countries (LDCs) and Non-Least Developed Countries, and perform several other robustness checks.
