Guidelines for Submission
We only post records that we can confirm and verify through fact-checking.
When you submit a record, be sure to provide a source that is publicly verifiable (e.g. a news report, a Facebook group, links to online photos with headcounts, etc) or describe the crowd-counting techniques used by onsite onlookers (e.g. sign-ins, counting through distributing flyers/handouts, counting from photos/videos, and/or other crowd density estimation techniques).
We will never post, release, or share identifying information that has not already been reported in the public domain.
Nevertheless, we urge you to avoid including personal identifying information in your submission.
