Risk Limiting Audit Summary and Artifacts

On December 14-15, 138 Georgia counties counted a random sample of ballots by hand as part of our post-election audit. We wanted this audit to be as transparent as possible. We could have published the machine-counted batch totals so that everyone could have followed along and verified on their own that the numbers matched as the hand counting occurred. However, if we did that before the audit, some might question whether that gave auditors a “number to hit.”

Therefore, in order to achieve transparency and audit integrity at the same time, we published a hash of county ballot manifests and machine counted batch totals:

CLICK HERE for a zip file with all ballot manifests and machine-counted batch totals from the election. A text file labeled “Jurisdictions” is available in the file folder to help identify the county for each file. You can confirm that these were the same batch tallies that we started the audit with by performing a SHA256 hash of the file and matching it to the hash above, which was published before counties began auditing.
