The role of data

Data at the community, state, and national levels can illuminate race-based disparities in the sentencing, incarceration, and all aspects of the criminal justice system. To inform efforts for a more equitable justice system, advocacy organizations, policymakers, and district attorneys offices are using data to understand where racial bias exists in the system, and push for solutions and policies to eliminate it.

Why it matters

While racial disparities inequities exist within every level of the justice system, it’s necessary to look to the root cause of disparities in justice involvement—arrests and sentencing—to understand how to make progress. From local police departments disproportionately arresting people of color to race-based disparities in sentencing, building a more equitable justice system starts from the ground up. Local data can expose harmful trends at the local level so advocates and decision-makers can be empowered to make change.

Police Data Initiative: Data on law enforcement indicators

The Police Data Initiative works with law enforcement departments who have released datasets on a number of indicators, from complaints against officers to community engagement. So far, the initiative includes 130 departments and over 200 datasets.

The Stanford Open Policing Project: Robust traffic stop data

On average, police officers in the U.S. make over 50,000 traffic stops per day. The team at Stanford Open Policing Project is collecting, analyzing, and sharing data on stops and outcomes: The dataset currently contains over 200 million records.
 

Prison Policy Initiative: Data on incarcerated populations by race

Disaggregated data on the incarcerated population by race/ethnicity is critical for understanding disparities. Prison Policy Initiative has made this data (current as of the 2010 Census) available for download and analysis.

Fatal Encounters: Data on police-related deaths

This publicly maintained dataset collects and categorizes every interaction between a member of the public and a police officer that results in a fatality, including officer involved shootings, but also suicides, fatal motor vehicle accidents, and accidental deaths. The data is extensively researched and includes information about the race, age, and location of each person in the data.

Federal Bureau of Investigation: National database on crime incidents

The FBI collects this data on arrests and incidents that is reported on a voluntary basis by law enforcement agencies in the U.S. Data on arrests includes the race of the person arrested, and data on some crimes include the race of the victim to allow for racial disparities in police arrest activity and crime victimization to be analyzed and linked by geographic region as well.
