T. Edwin Chow

Based on the crowdsourced trajectory data and videos recorded during the July 1st rally in Hong Kong, the estimated count of the mobile crowd was 27,832. The results have just been published on The StandNews. Just for reference, the organizer reported more than 60,000 people attended; the police estimated the peak attendance was 14,500; HKUPOP estimated the attendance is ~30000; and another HKU team leaded by Prof. Paul Yip estimated the count to be 16,000. Below is a chart from HKUPOP documenting the count during 2003-2017.
