The State of Firearm Policy Research in the United States.

Firearm-related deaths lead to the most person-years of life lost in the US. There were 48,830 deaths from homicides and suicides in 2021 alone. Firearm access remains at an all-time high in most states - indicated by record manufacturing, sales, employment in firearm industry, taxes collected from sales, and the number of federal background check applications in 2020 and 2021. Yet, firearm injury is a politically contentious topic to the point of stalling progress on an important public health topic. This politicization led to nearly three decades of federal disinvestment in firearm research; reduced surveillance of firearm-related crime, injury, and death; and degraded data quality. This left generations of researchers with limited epidemiologic tools to conduct firearm policy research, jeopardizing the amount and quality of research conducted. Despite these limitations, research has persisted and promising approaches to reduce firearm morbidity and mortality have been identified. Yet the field has struggled to keep pace with methodological advancements and conceptualizations of racial and ethnic disparities as products of systemic racism. In this commentary, we highlight some existing evidence-informed policies, explicate some limitations in the field, and identify opportunities to address the limitations of prior work to strengthen future capacity for evidence-informed prevention.
