Accountability
Corrections
Every error we find, or that a reader or an official’s office reports to us, is logged here — including the ones we haven’t fixed yet.
Not just the scores: a wrong date, a misspelled name, a committee someone already left. Publishing our own mistakes is cheaper than having someone else document them for us, and a site that asks people to trust what it says should show its working when it gets something wrong.
No corrections logged yet.
This log starts from the date it was published and will not be backfilled — reconstructing a correction history after the fact would be guesswork, and a corrections log that cannot be trusted is worse than none. An empty log means nothing has been reported since it opened, not that the site has never been wrong.
For how the numbers are produced in the first place, see the methodology and the bulk data page.
