San Francisco Campaign Finance Committees and Filer Registry

Active and terminated campaign committees and non-committee filers registered with the San Francisco Ethics Commission. The dataset is created from an export of the Commission's filer database and is updated nightly via a script that runs at midnight Pacific time. The City of San Francisco maintains this data, with the last update recorded on March 22, 2026.

Use Cases

Strengths

• Updated nightly via an automated script, suggesting regular maintenance.
• Contains join keys (properties suffixed with '-nid') for linking with related datasets.
