Welcome to PDAP!
We're making a unified archive of police data.
Read more about our mission at

We're a small but growing multidisciplinary community of transparency-minded people. We meet in Discord. The core PDAP staff keeps the lights on, the non-profit board empowers our work, and the broader community moves the mission forward step by step.

We need help from anyone who can use a computer to contribute to our database of Data Sources. Start here.

You can share the results of your hard work with our community, and add yourself as a Data Source. Start here.

Participate in the information ecosystem! People with relevant experience can give feedback and serve as a sounding board in Discord, or by booking time to talk.
Anyone with a network of trusted friends and collaborators can text, email, or DM our website to a friend who might be able to contribute.

You can use your scripting and automation skills to help us bring our Agencies and Data Sources up to date.
Coders of any experience level can write data scrapers...and more importantly, share the results! This works best if you're trying to answer a question or do something you think is useful. Python is our preferred language; ultimately, use what makes you happy.

If you have a question you'd like to answer about the police, reach out to [email protected] or in Discord. Our community of experts of volunteers may be able to help you. We're in the early days—your project could be one of our first case studies.
