Occurrence research focuses on the investigation and analysis of events, incidents, or phenomena that happen in a specific context or environment. This research area aims to understand the frequency, causes, consequences, and patterns of these occurrences, with the goal of improving prevention, mitigation, and response strategies. Researchers in this field may use a variety of methods, including data collection, statistical analysis, case studies, and simulations, to study the occurrence of various events such as natural disasters, accidents, epidemics, crimes, or social phenomena. The findings from occurrence research can help inform policymakers, practitioners, and the public about potential risks and ways to address them effectively.
