To get the estimates of Fatal Police Shootings at the county-level, both overall and for Black, Latinx, and white shootings, you can download a CSV of the data here. Note that shootings for all other races can be calculated by subtracting the Black, Latinx, and White shootings from the overall counts.
A second database provides information on the estimates of Fatal Police Shootings of youth (defined as 10-24), also at the county-level. These are also broken up by shootings overall, and for Black, Latinx, and white shootings. A CSV of the data is here.
The data for this project is released on a rolling basis. All data not protected by copyright is or will be made freely available for downloading.
