Himpunan Kebangkitan Rakyat #KL112 Crowd Estimate
Himpunan Kebangkitan Rakyat (People’s Uprising Rally / #KL112) was a protest rally held at Stadium Merdeka, Kuala Lumpur on January 12th, 2012. It was organised by Pakatan Rakyat and various NGOs.
At its peak the crowd is estimated to have been between 63,976 – 78,193 people. This number is not expected to be revised, unless some new evidence surfaces to suggest a different crowd size.
Methodology
Photos and videos that showed the size of the crowd were evaluated. These were used to determine the extents of the area covered by the crowd and the crowd density. The area was then refined by removing obstacles and estimating the percentage of space used. A crowd density of 4 – 12 sq.ft. per person was used.
Building the polygons
After initial evaluation of the photos, one was chosen as a reference to build the polygons from. The polygons were then adjusted after evaluating photos and videos. The steps are shown in the diagram below:
- The original photo
- Satellite photo, perspective-adjusted
- The original photo, perspective-adjusted to match the satellite photo
- The completed polygons on the map
Result
The polygons in the map below shows the extents of the crowd, divided into different zones. The total space covered by the polygons is 456,627.05 sq. ft. The space taken up by the crowd is 275,532.03 sq. ft. These measurements do not include the stadium seating.

B = 1,188 people
C = 8,652 people
D = 2,474 people
E = 7,428 people
F = 1,221 people
Stadium seating = 30,000 people
Total = 71,085 people
Margin of error is +/- 10%.
The estimated size of the crowd is 63,976 – 78,193 people.
