The incidence of people dying due to use of force by the police is a high profile issue at the moment. Figures about the distribution of these deaths, such as found in this paper, can be compared to population statistics to demonstrate how different demographics are affected at different rates to those of the general population.
We can also compare the demographics of the officers involved in these deaths (table 6) to the demographics of the police force as a whole, and see the features that are overrepresented. For example 67% of police are white but 84.3% of officers involved with the deaths are, indicating a hazard ratio of 2. However the largest effect I have found is that of sex, in that males make up 84.9% of police but account for 97.4% of deaths, indicating a hazard ratio of 5.8.
Does this represent the true risk, in that your chance of dying in an encounter with the police is nearly 6 times greater if that police officer is male compared to female, or is there another explanation? For example, a policy of assigning female officers to lower risk areas or roles would explain this observation.
