The data behind our work
Every record here starts as a public filing that anyone can download free. What we do is make these sets usable through joining and analysis: donors resolved into real people, lobbying payments tied to specific council files, roll calls turned into an attendance record, and crime counted consistently across LAPD's 2024 system change. Our articles run on these datasets, and you can license them for your own work below.
Bundles ship as CSVs with a README. Contact data@basin.la for access and licensing.
Free downloads
8 of our datasets are free to download right now, no request and no account. Each zip holds the CSVs and a single plain-text document carrying the method, the column meanings, the sources and the license. The rest of the catalog is licensed below.
