ESA and NASA maintain asteroid hazard lists that contain all known asteroidswith a non zero chance of colliding with the Earth in the future. Some softwaretools exist that are, either, capable of calculating the impact points of thoseasteroids, or that can estimate the impact effects of a given impact incident.However, no single tool is available that combines both aspects and enables acomprehensive risk analysis. The question is, thus, whether tools that cancalculate impact location may be used to obtain a qualitative understanding ofthe asteroid impact risk distribution. To answer this question, two impact riskdistributions that control for impact effect modelling were generated andcompared. The Asteroid Risk Mitigation Optimization and Research (ARMOR) tool,in conjunction with the freely available software OrbFit, was used to projectthe impact probabilities of listed asteroids with a minimum diameter of 30 monto the surface of the Earth representing a random sample (15% of all objects)of the hazard list. The resulting 261 impact corridors were visualized on aglobal map. Furthermore, the impact corridors were combined with Earthpopulation data to estimate the simplified risk (without impact effects) andadvanced risk (with impact effects) associated with the direct asteroid impactsthat each nation faces from present to 2100 based on this sample. Therelationship between risk and population size was examined for the 40 mostpopulous countries and it was apparent that population size is a good proxy forrelative risk. The advanced and simplified risk distributions were compared andthe alteration of the results based on the introduction of physical impacteffects was discussed. Population remained a valid proxy for relative impactrisk, but the inclusion of impact effects resulted in significantly differentrisks, especially when considered at the national level.
