Thanks for the quick response! I’m one of the organizers of the San Diego event, which we estimate (using published protocols for estimating crowd size [https://digital.sandiego.edu/cgi/viewcontent.cgi?article=1022&context=krocschool-faculty] ) was about 35,000–3 times the police estimate of 12,000. We need as much accuracy and transparency in publishing numbers of protesters, so any further details on how the 5.2 million number was calculated would be extremely helpful.

We are working on a “how to” document, to be shared with others, on estimating crowd size —

So important for perception of our strength and unity and also for future planning efforts where routes, locations and crowd safety all depend on how many show up.

Thanks!!! Alt National Parks shared that they collaborated with 20,000 volunteers and law enforcement to reach their count.
