That’s not the case, according to this latest study. Using a regression model, researchers found that on average a doubling of the population under the path of a tornado leads to a 21 percent increase in the casualty rate, while a doubling of the energy dispersed by the tornado leads to a 33 percent increase in the casualty rate.
