An Analysis into Relationships that may Exist between Population and the Reported Number of Tornadoes in the Continental United States

Many studies have suggested that the tornado database is biased by the concentration of human observers. Some studies have shown a possible 66% decrease in tornado reporting can be directly attributed to population density. This study examines whether or not such biases exist throughout the United States. Population data are compared to the historical tornado database in order to better understand the relationship(s) between each variable. Various statistical and spatial techniques are implemented in order to better identify relationships. As expected, weak (F0-F1) tornadoes show a correlation to both population patterns and travel routes. However, not all regions of the United States share the same relationships during the study period. Therefore, any meaningful adjustment to the tornado climatology cannot be made because of the variation in both spatial and temporal changes.
