# FEC data dictionary

Snapshot: 2026-11-09.

Null percentages are exact full-source-table counts rounded to one decimal place. Examples are omitted. Statistics for v_candidate_totals, v_daily_donations, and v_top_donors are unavailable; their SQL definitions are unchanged.

Join entity IDs with `cycle`. Aggregate child transactions before joining to avoid fan-out. Values are source fields, not validated identities; donor strings are not a reliable unique-person key.

Contributor names/addresses are subject to [FEC use restrictions](https://www.fec.gov/updates/sale-or-use-contributor-information/).
