The United States has the highest rate of gun-related deaths among industrialized countries, with more than 30 000 fatalities annually. To date, research on gun violence has been limited. A 1996 congressional appropriations bill stipulated that “none of the funds made available for injury prevention and control at the Centers for Disease Control and Prevention [CDC] may be used to advocate or promote gun control.” Similar restrictions were subsequently extended to other agencies (including the National Institutes of Health), and although the legislation does not ban gun-related research outright, it has been described as casting a pall over the research community. This study sought to determine whether funding and publication of gun violence research are disproportionately low relative to the mortality rate from this cause.
