About the Initiative:

The Police Data Initiative is a law enforcement community of practice that includes leading law enforcement agencies, technologists, and researchers committed to engaging their communities in a partnership to improve public safety that is built on a foundation of trust, accountability and innovation. The PDI represents the great work and leadership of more than 120 law enforcement agencies who have released more than 200 datasets to date, and originated as a result of several recommendations in the Task Force on 21st Century Policing that focused on technology and transparency.

Yes, the site is designed to serve as a virtual resource for law enforcement agencies that are part of the Police Data Initiative but can be used by anyone or any agency producing, releasing or consuming open data.

At the national level, the U.S. Department of Justice’s Office of Community Oriented Policing Services (COPS Office) serves as the primary federal agency providing support to the PDI, however the COPS Office nor any federal agency collects any data released by the agencies participating. See the FAQs under “Data” for more information. This website is operated by The National Policing Institute, a national non-profit organization, in partnership with many other organizations, including the International Association of Chiefs of Police (IACP).

About the Data:

More than 200 datasets are currently being made available by participating agencies. The list of datasets is constantly growing and evolving. This website maintains a listing of datasets that can be viewed, sorted, and searched under the Data and Agencies tab of this site.

The agencies participating in this community of practice have chosen to release their data to the public, therefore anyone can collect the data. However, it is important to note that this initiative, the DOJ COPS Office, nor The Police Foundation are collecting this data at the national level. This website only provides an index to these agency’s webpages where the data can be downloaded by the public.

No specific data is required and participating agencies are able to determine what data about crime and/or policing they prefer to release. We encourage those determinations to be made in light of local restrictions, privacy implications, data availability and cost, and community demand for such data.

Open data is data that can be downloaded and analyzed by another person or organization. For this to be possible, the data must exist in a format that allows analysis, meaning that it is not summary but incident level and in a file format that allows the data to be accessed. Formats such as PDF and HTML don’t typically allow the data to be downloaded and analyzed and therefore data stored in these file formats generally don’t meet the definition of open.
