In January of 2021, the FBI changed the way crime data are collected and reported, which has impacted the reliability of subsequent data. That year, the FBI retired the SHR system and replaced it with the National Incident-Based Reporting System (NIBRS). While NIBRS will eventually provide much more comprehensive and robust crime data compared to the SHR, transitioning law enforcement agencies to the new data collection and reporting system has been slow and burdensome. Indeed, many law enforcement agencies did not transition to NIBRS by January of 2021, which has had a significant impact on the reliability of 2021 crime data. After a careful analysis of that year's crime data, the VPC has determined that current NIBRS data are not reliable for state-by-state gun violence research as required by When Men Murder Women.Lacking reliable crime data from 2021, this report will instead focus on trends revealed in previous editions of When Men Murder Women over the past 25 years. Previous years' reports described the age and race of victims, weapons used, the relationship between victim and offender, and circumstance. Prior reports also ranked the states by their rates of females killed by males. This study summarizes the findings of these reports and the patterns and characteristics of these homicides between 1996 and 2020.
