The data behind our work
The Basin's articles run on these datasets, which are built from public data and then joined and cleaned, so donors are resolved into real people, lobbying payments are tied to specific council files, roll calls become an attendance record and crime is counted consistently across LAPD's 2024 system change. You can license them for your own work below.
Bundles ship as CSVs with a README. Contact data@basin.la for access and licensing.
