County Demographics and COVID-19 Death Rates: Comparison of relationship in the first and current stage of the pandemic in the United States of America

Previous studies have discovered disparity in death rates associated with SARS-CoV-2 infection in the United States during the initial stages of the pandemic. Specifically, the death rates were higher in the population in poverty and communities of color across the United States. In the current study, we perform the secondary analysis of death rates due to COVID-19 data, obtained from the Center for Disease Control and Prevention (CDC). Results indicate that in the first phase of the pandemic (February 1 to August 1, 2020), counties with higher percentage of White, Native Hawaiian and other Pacific Islanders, and two or more races populations were found to have lower per-capita COVID-19 death rate. Whereas counties with population having higher percentage of females, Black or African American people, and persons in poverty had higher death rates. Analysis of the death rates from August 1 to September 10, 2020, indicate that disparity continues with counties having higher population of Black or African American people and female having higher death rates. Poverty is not a significant variable in determining the death rates due to COVID-19. Based on the current data and lack of detailed molecular mechanism of the disease, we suggest that more resources must be diverted to counties with higher percentages of Black or African American and female populations.
