", "\nAbstract\n\nResearch Summary\nIn response to highly publicized, controversial police killings of Black Americans, policymakers and advocates have proposed several police reforms, including a recurrent, decades‐long demand for police departments to diversify their forces to better match the racial composition of the communities they serve. We draw on a unique police agency‐level dataset comprising 1,988 local police agencies and regress measures of police killings of Black, Hispanic, and White Americans from 2013 to 2018 onto racial congruence ratios and other theoretically relevant predictors. The results provide support for the hypothesis, revealing a negative association between racial congruence and police killings among Black and Hispanic victims.\n\n\nPolicy Implications\nOur results suggest that for at least some local police departments, increasing the racial/ethnic representation of officers might lower police killings of people of color. This implication offers some optimism amid impassioned demands to decrease police killings of Black Americans, specifically, and reform policing.\n\n"]
