Decision-making as it relates to tornado warnings is heavily researched. However, many of these studies do not incorporate a spatial analysis of tornado warning decisions comparing them to different geographical locations and populations. This study uses data from a simulated tornado warning decision experiment to examine how decision-making varies across the United States. First, multilevel regression analysis and poststratification (MRP) is used to determine if there are certain “types” of people that are more prone to making incorrect decisions and estimating geographically where these populations might be located. Second, these results are compared to the Social Vulnerability Index to see if these locations coincide with pre-determined locations of social vulnerability to environmental hazards. The preliminary results will be presented.
