We evaluated the influence of population size (POP), HDI (Human Development Index) and GDP (gross domestic product) on the COVID-19 pandemic in the Southeast region of Brazil, between February 2020 and May 2021. Methods: Cases, deaths, incidence coefficient, mortality rate and lethality rate were compared among states. The cities were divided into strata according to POP, GDP, and HDI. Data were compared by Welch&rsquo:s ANOVA, nonlinear polynomial regression, and Spearman&rsquo:s correlation test (rS). Results: The highest incidence coefficient (p <: 0.0001) and mortality rate (p <: 0.05) were observed in the states of Espí:rito Santo and Rio de Janeiro, respectively. Until the 45th week, the higher the POP, the higher the mortality rate (p <: 0.01), with no differences in the remaining period (p >: 0.05). There was a strong positive correlation between POP size and the number of cases (rS = 0.92, p <: 0.0001) and deaths (rS = 0.88, p <: 0.0001). The incidence coefficient and mortality rate were lower (p <: 0.0001) for low GDP cities. Both coefficients were higher in high- and very high HDI cities (p <: 0.0001). The lethality rate was higher in the state of Rio de Janeiro (p <: 0.0001), in large cities (p <: 0.0001), in cities with medium GDP (p <: 0.0001), and in those with high HDI (p <: 0.05). Conclusions: Both incidence and mortality were affected by time, with minimal influence of POP, GDP and HDI.
