Data Sources

A map scattered with icons representing different kinds of data.

We locate, describe, and share sources of data about police agencies across the United States, which are generally public record.

Criminal legal systems in the United States are decentralized, and managed locally. In response, we facilitate local research and organizing to keep the data in context. The goal is a relevant database, and impactful open-source tools.

Other things we're building with data

We create automatic archives of data sources, so they are not lost to time and poor data retention policies. Fragile URLs are turned into lasting resources for future use.
We're mapping what is available in each jurisdiction, and advocating for transparency. What kinds of research are possible? What does model transparency look like?
