Mapping Police Violence is an organization and independent research collaborative collecting data to quantify the impact of police violence on communities. The Mapping Police Violence database is updated with new cases every weekend. Since it takes roughly a week to find and code cases, the data and analysis on this site usually includes all killings by police that occurred up to the end of the prior week. Additionally, they conduct quarterly reviews of cases from prior years to ensure our database remains complete and up-to-date.
