What this figure is and is not. It counts deaths recorded as occurring during an encounter with this agency. It is not a finding of wrongdoing, and a death being recorded here says nothing about whether it was lawful. Many involve armed confrontations; some involve none. Police Census publishes counts only and does not name the people who died.
These records are compiled from news reports and public records by Mapping Police Violence, an independent research organisation — they are not official statistics, and no federal database records this comprehensively. Used with permission.

Jurisdictions overlap. These agencies are also recorded against the same county, so a single address may be covered by more than one of them.
