Use of Population Weighted Density Index for Coronavirus Spread in the United States.

Understanding how population density affected the transmission of COVID-19 is vitally important, since crowded cities were the epicenters for the disease. Since human contact was the main cause of the spread, population-weighted densities have been shown to be a better measure than conventional densities, since the variation in density across subareas matters more than the density in the total area. This study investigates the impact of population-weighted density and other demographics on the rate of COVID-19 spread in the United States.
